Rings

DESCRIPTION: The side stones on this ring are emerald, princess and round cut diamonds set together, three different outlines along one band. They total 1.75 carats and are G in color and VS in clarity. The emerald cuts are step cut and give broad flat flashes, while the princess and round stones are brilliant cut and scatter light into fine points, so the shoulders produce two kinds of light instead of one. The center stone is a 2.01 carat princess cut diamond, GIA certified at I color and SI2 clarity, measuring 7.12 by 6.76 by 4.81 mm. Its polish and symmetry are both graded very good, and it shows faint fluorescence. Total diamond weight across the ring is 3.76 carats. Faint fluorescence means the stone glows slightly under ultraviolet light; at the faint level it is not something you see in ordinary daylight or indoor lighting. I color is near colorless with a trace of warmth, and SI2 means inclusions are not visible to the naked eye. The mounting weighs approximately 5.4 grams in 18K white gold and the ring measures 7 mm, a quarter of an inch, in width.

DESCRIPTION: This ring is listed without carat weights, so what you can judge it on is the quality of the stones and the way it is built. The diamonds are G to H in color and SI2 to SI3 in clarity, and the design sets a round cut diamond at the center of a field of round and baguette cut diamonds in 14K white gold. The mix of cuts is what makes it work. Baguettes are step cut, with long flat facets that produce wide sheets of white light, while the round brilliants break the same light into small moving points. Set together across a frame 0.32 inches wide, the two behave differently as the hand turns, so the ring never settles into one static shine. G to H is the near colorless range and shows no warmth against white gold. SI2 to SI3 is the band where inclusions are generally invisible at arm's length but can be found at close range by a careful eye, and it is the reason a ring with this much diamond coverage is priced the way it is. Different ring sizes may be available; please inquire for details. DETAILS: Item Code CR748D Diamond Clarity SI2, SI3 Diamond Color G, H Metal Color White Metal Type 14K Gold Width 0.32 inches

DESCRIPTION: Clarity on this ring is VVS2, which is two full grades above the point where inclusions stop being visible to the naked eye and into territory where they are difficult to locate even under magnification. Most engagement rings are not built to that standard, and almost none are at this price. The center is a fancy yellow princess cut diamond weighing 2.05 carats, GIA report number 5151513207. Small round cut white diamonds surround it and add 1.33 carats, for a total diamond weight of 3.39 carats. The white stones are G in color, in the near colorless range. The head measures 14 mm, or 9/16 of an inch, across. The mounting weighs 5.7 grams in 18K white gold. A 14 mm head on a mounting that light is a deliberate ratio: it is why this ring covers as much of the finger as rings carrying twice the diamond weight. The yellow center and its white surround do all the work, and the metal stays out of the way.

DESCRIPTION: Nothing about the shape of this ring is unusual, and that is the point of it: a 2.00 carat round brilliant, GIA certified at H color and SI1 clarity, set in platinum with brilliant round cut side stones adding 0.88 carats. Total diamond weight is 2.88 carats. The money here went into the specification rather than into the styling. The frame measures 7 mm, a quarter of an inch, in width and the mounting weighs 11 grams. That is a great deal of metal for a ring of those dimensions, and it is what platinum does: at identical measurements it comes out heavier than gold, and the extra density means prongs that flex less and wear down more slowly. The accent stones are F to H in color and VS1 to VS2 in clarity. H color is near colorless and SI1 means inclusions are not visible to the naked eye. Together those two grades describe a stone that looks white and clean in the hand without paying for distinctions only a loupe can find. Platinum also keeps its white color permanently, where white gold needs its rhodium plating redone every few years. Made at Avianne and Co in New York City's Diamond District.

DESCRIPTION: The center stone here is a 3.11 carat clarity enhanced diamond, graded H in color and VS2 in clarity, set in 14K white gold. H is near colorless and shows no visible warmth against white metal, and VS2 means no inclusions are visible to the naked eye. The clarity enhancement is stated plainly, because it is the reason a three carat stone with these grades is priced where it is rather than several times higher. Total diamond weight across the ring is 4.61 carats, which puts 1.50 carats into the surrounding diamonds; those run G to H in color and VS1 to VS2 in clarity, so the accent work matches the center rather than sitting below it. The mounting weighs approximately 8 grams. Three carats is roughly where a center stone stops being noticed only at conversation distance and starts being noticed across a room, and the step up from two carats shows mainly as width across the finger rather than extra depth.

DESCRIPTION: Two things happen on this ring at once: the shank splits into two bands as it approaches the head, and the center stone is ringed by a double halo. The split opens a window of skin on either side of the halo, which keeps a 14.8 mm head from reading as a solid slab of metal across the finger. The center stone is a cushion cut diamond weighing 4.13 carats, described as fancy white and clarity enhanced. Side stones are detailed all the way around the band and add 1.50 carats, for a total diamond weight of 5.63 carats. Those stones are F to H in color and VS1 to VS2 in clarity, so no inclusions are visible to the naked eye anywhere on the ring. The mounting is 18K yellow gold and weighs 8.5 grams. A double halo is the most efficient way to add apparent size: the inner row reads as part of the center stone and the outer row as its frame, so a 4.13 carat cushion presents with the footprint of a considerably larger solitaire. The clarity enhancement on the center stone is stated here rather than left out, because it is part of what the stone is and part of why it is priced where it is.

DESCRIPTION: A natural canary diamond cut as a princess is an unusual pairing. Fancy yellows are most often cut as cushions or radiants; a princess keeps sharp square corners and a flatter, more open table, so the yellow reads as an even wash of color across the whole stone rather than pooling in the middle. This one weighs 4.90 carats and is EGL certified at SI1 clarity. Small round cut white diamonds are pave set half way across the band, adding 1.50 carats for a total diamond weight of 6.40 carats. Those accent stones are G to H in color, which is the near colorless range, putting them a clear step away from the canary center instead of blending toward it. The center frame measures half an inch in width. The mounting is 18K white gold and weighs approximately 9 grams. White metal is the standard choice behind a yellow diamond for the same reason a white mount is used behind a colored print: it gives the eye a neutral reference, and the stone reads more saturated than it would against yellow gold. SI1 means no inclusions are visible to the naked eye.

DESCRIPTION: Sixteen round cut diamonds are prong set across the band of this ring rather than pave set, which is why the sides read as a row of distinct stones with metal between them instead of one continuous glittering surface. Those sixteen stones weigh 3.20 carats together and are G in color and VS1 in clarity. The center diamond is a 4.11 carat round brilliant, EGL certified at I color and SI3 clarity. Total diamond weight across the ring is 7.31 carats. The center measures 3/8 of an inch, or 10 mm, across and the 14K white gold mounting weighs approximately 9.7 grams. SI3 sits below SI2, and it is the grade where an inclusion can become visible to a careful eye at close range, usually as a small dark point rather than anything cloudy. It is also the main reason a stone of this size is available at this price: at VS clarity the same 4.11 carats would cost a multiple of it. The side stones are a cleaner and whiter grade than the center at VS1 and G, which keeps the frame bright around it.

DESCRIPTION: This ring weighs 20.7 grams in platinum, roughly double the mounting weight of most engagement rings this size. You notice it the moment you pick it up, and you keep noticing it on the hand: a ring built with this much metal sits firmly and does not rotate on the finger the way a light shank does. The center stone weighs 3.00 carats and is graded H to I in color and SI1 in clarity. The side stones add 2.00 carats, so total diamond weight is 5.00 carats, split roughly 60/40 between the center and the surrounding work. The frame measures 10 mm, or 3/8 of an inch, in width. SI1 means inclusions are not visible to the naked eye, and H to I is the near colorless range. Platinum needs no rhodium plating to stay white, where white gold has to be replated every few years to hold the same color, so a ring made this heavily in platinum will look the way it does now in twenty years' time.

DESCRIPTION: Total diamond weight on this ring is 10.65 carats, and the band is set with diamonds the whole way around rather than stopping at the shoulders. The center is a prong set round brilliant weighing 6.42 carats; the small round cut diamonds covering the full circumference account for the remaining 4.23 carats. A fully set band means there is no plain metal anywhere on the finger, so the ring stays lively from every angle, including the palm side where most rings go dark. It also means the shank cannot be cut and rejoined for sizing the way a plain band can, so the finger size is worth confirming before ordering. Diamonds across the ring are G to H in color and SI1 to VS2 in clarity. The frame measures 4.2 mm in width and the mounting weighs 8.7 grams in 14K white gold, which is restrained for a ring carrying close to eleven carats. G to H sits in the near colorless range and shows no warmth against white metal, and SI1 to VS2 means inclusions are not visible to the naked eye.

DESCRIPTION: The head on this ring is a floating prong. The center diamond, a round cut stone of 2.00 carats total weight, is held on prongs that lift it clear of the diamond work beneath it, so the stone sits above the ring rather than down inside it and light reaches its pavilion from the sides as well as the top. The center stone is VS2 in clarity and carries report number 2135161682. The frame is fully outlined in brilliant round cut diamonds graded F to G in color and VS1 to VS2 in clarity. F to G straddles the line between colorless and near colorless, which is why the surrounding stones read bright white against the 14K white gold rather than slightly gray, as lower color melee often does. VS1 to VS2 means no inclusions are visible to the naked eye anywhere on the ring. The band measures approximately 4.5 mm in width and the mounting weighs approximately 5 grams. That is a narrow shank beneath a two carat head, and the contrast is the whole design: with so little metal competing with it, the center stone registers as larger than the same stone would in a heavier mounting.

DESCRIPTION: Nearly 90 percent of the diamond weight on this ring is in a single stone. The center diamond weighs 4.9 carats and is graded H to I in color and VS2 to SI1 in clarity. The round cut side stones add only 0.63 carats, for a total diamond weight of 5.53 carats across the ring. That balance is a choice. Rings at this total weight more often spread it across a halo and a fully set band, which buys coverage across the finger; this one keeps it in the middle, which buys presence in one place. The frame measures 9.3 mm, a third of an inch, in width. The mounting is platinum and weighs 14.5 grams, heavy even for the metal. Platinum is denser than gold, so the same design comes out with more material in the shank and in the prongs, and prongs with that much metal behind them hold a large stone more securely over years of daily wear. H to I is the near colorless range, showing at most a hint of warmth against white metal, and VS2 to SI1 means no inclusions are visible to the naked eye.

DESCRIPTION: A fancy yellow pear shape diamond of 4.70 carats sits at the center of this platinum ring, EGL certified at VS clarity. Natural yellow diamonds of this weight are uncommon, and the pear is the outline that shows the color best, because the long tapered pavilion returns the body tint along the whole length of the stone instead of concentrating it under the table. The side stones repeat the center's shape. Two pear cut diamonds of 0.50 carats each are set on either side of the head, and small round cut diamonds are pave set half way across the band for a further 1.00 carat. The white diamonds on this ring are E to F in color and VS1 to VVS1 in clarity, so they read as colorless alongside the yellow rather than muddying it. Total diamond weight is 6.73 carats. The platinum band weighs approximately 11.4 grams. Platinum stays white permanently without rhodium plating, which matters more than usual on this ring: a white gold mounting whose plating wears toward yellow would sit directly against a yellow center stone and cost it contrast. E to F is the colorless range, the top of the color scale.

DESCRIPTION: The center of this ring is a 3.12 carat round brilliant diamond, GIA certified at J color and SI1 clarity, set in 18K white gold. Small round cut diamonds along the sides add 1.00 carat, for a total diamond weight of 4.12 carats across the ring. J color is the last grade in the near colorless range. Against white gold a J shows a trace of warmth in the body of the stone, and that is the honest trade being made here: color grade moves price steeply once a round passes three carats, so a J center buys noticeably more size than a G or an H would at the same spend. Clarity across the ring runs SI1 to VS1, which means nothing in these stones is visible without magnification. The mounting is deliberately light at 5.2 grams, with the band tapering away from a head that measures 3/8 of an inch, or 10 mm, across. Less metal around the girdle leaves more of the round brilliant open to light from the sides, and a slim shank under a three carat stone keeps the proportion firmly in favor of the diamond.

DESCRIPTION: Two trapezoid cut diamonds flank the center stone on this ring, a cut you will rarely see on an engagement ring and the reason this one looks nothing like a halo design. The center diamond weighs 5.00 carats, is princess cut, and carries an EGL certificate at I color and SI1 clarity. The two trapezoids add 0.63 carats, bringing total diamond weight across the ring to 5.63 carats. A trapezoid is cut with a flat top and angled sides, so the side stones sit flush against the square edges of the princess center with no gap and no metal showing between them. The effect is one continuous block of diamond rather than three separate stones. The mounting is 18K white gold and weighs approximately 9.6 grams, and the ring measures 3/8 of an inch, or 10 mm, in width. I color sits at the warm end of the near colorless range, and SI1 means inclusions are not visible to the naked eye. The princess cut holds its weight in a compact square outline, so 5.00 carats reads as depth and substance rather than spread. The head is also built as a neutral platform, which makes this a practical mounting if you later want to set a different center stone of similar dimensions.

DESCRIPTION: A 7.17 carat cushion cut diamond set in platinum, EGL certified at L color and SI2 clarity. Total diamond weight across the ring is 8.92 carats. The halo on this ring floats. The pave ring sits slightly away from the center stone instead of hugging its girdle, which lets light reach the sides of the cushion that a tight halo would block, and keeps the center reading as its own object rather than merging into the surrounding stones. The pave totals 1.75 carats and the head measures 16 mm across. Platinum mounting, 9.2 grams. Platinum is denser than gold, so the same design comes out heavier and the prongs hold their grip longer under daily wear. It also stays white permanently, where white gold needs its rhodium plating redone every few years. SI2 inclusions on a stone this size are visible under magnification but not to the naked eye at arm's length. Made at Avianne and Co in New York City's Diamond District.

DESCRIPTION: A 6.61 carat round brilliant sits at the center of this 18K white gold engagement ring, EGL certified at L color and SI1 clarity. Total diamond weight across the ring is 9.61 carats. The remaining 3.00 carats are split between baguette and round cut diamonds set along the shoulders. Mixing the two cuts changes how the band behaves in light: the baguettes throw broad flat flashes while the rounds scatter, so the sides stay active instead of reading as one continuous line of sparkle. The head measures 3/4 of an inch across and the mounting weighs 12.3 grams. L color sits in the faint range, which at 6.61 carats reads as a warm tint rather than a colorless stone. Color grade moves price sharply at this size, so an L center buys considerably more carat weight than a colorless one for the same money. SI1 means inclusions are not visible to the naked eye.

DESCRIPTION: An 11.44 carat princess cut diamond is the entire point of this ring. The center stone is prong set in 18K white gold and carries a Gemological Appraisal Industry certificate, report number 7494208. Total diamond weight across the ring is 13.19 carats at VS1 to VS2 clarity and G color. The remaining 1.75 carats are round cut diamonds running along the shoulders, scaled to frame the center without competing with it. The head measures 15 mm across, which covers most of the finger between the knuckles. The mounting weighs 11 grams in 18K white gold. VS1 to VS2 means no inclusions are visible to the naked eye. G color sits in the near colorless range and shows no warmth against white metal. At 13.19 carats total this is the largest engagement ring in the Avianne collection.
