Lab Chains

DESCRIPTION: This high-end tennis chain features a unique combination of emerald-cut and pear-shaped diamonds, creating a bold and distinctive look that stands apart from traditional designs. Each stone is individually set to maximize brilliance while maintaining a clean, structured layout throughout the chain. With an impressive 55 carats of Lab diamonds, this piece delivers exceptional shine and presence. The alternating fancy cuts add dimension and movement, making the chain stand out from every angle. Crafted in solid gold and finished with a secure clasp, this piece is built for both luxury and durability. Designed for those looking for something beyond a standard tennis chain, this is a true statement piece with elevated detailing and premium craftsmanship.

DESCRIPTION: Round brilliant lab diamonds set in a 4-prong graduated design — stones increase in size as they approach the center of the chain, creating a natural taper that sits with more elegance on the neck than a uniform-width tennis chain. The 24-inch length gives it more presence and drape than a standard 20 or 22-inch, and at 57.3 grams of 10K white gold the chain has genuine weight to it. 47.96 carats of lab grown diamonds across a 24-inch chain in this stone size is a combination that's hard to find at this price. Lab diamonds carry the same physical and optical properties as natural — identical hardness, identical brilliance, graded by the same standards — and at this carat weight the visual difference between lab and natural is zero. The graduation is what sells it in person: the taper keeps the chain from reading as a uniform band of stones and lets it follow the neckline naturally.

DESCRIPTION: A 4-prong tennis chain in 10K yellow gold — the round brilliant diamonds increase in size toward the center of the necklace, giving it a natural taper that sits differently than a uniform tennis chain. At 22 inches and 61 grams, there's real weight to this piece, and 83.15 carats of lab grown diamonds across the full length means the coverage is exceptional at this price point. Lab grown diamonds deliver the same brilliance and physical properties as mined stones at a fraction of the cost. For buyers looking for a heavy graduated diamond tennis chain in yellow gold with serious carat weight, this hits a value point that natural diamonds at this CTW simply can't touch.

The infinity link is one of the heaviest, most aggressive diamond chain silhouettes Avianne & Co. produces — a 9mm-wide Cuban-style link where every surface is paved with lab grown diamonds. At 126.5 grams and 15.7 carats in the 22-inch length, this chain carries the kind of weight and presence that announces itself before you walk into the room. VS2 clarity, G-H color lab diamonds are set across the top and sides of each link for continuous sparkle from every angle. The infinity link design locks each link into the next with no gaps or exposed gold between connections, creating a smooth, fluid surface of diamonds that moves naturally with the body. Lab grown diamonds are chemically and optically identical to mined stones — same fire, same brilliance, same durability — at a fraction of the traditional price point. A hidden box clasp with double safety latch secures the chain without interrupting the link pattern. Available in 14K yellow, white, and rose gold across multiple lengths ranging from 16 to 44 inches — diamond carat weight and gram weight scale proportionally with each size. Every piece is custom built at the Avianne & Co. workshop in New York's Diamond District.

DESCRIPTION: A single lab diamond cut into the shape of the letter itself — not a gold letter set with small stones. The whole initial is one 1 carat stone, held in a thin bezel of gold that traces its outline and nothing more, so from the front you see diamond across the entire letter with only a hairline of metal around the edge. The bail is built into the top of the letter rather than hung off it, which keeps the pendant sitting square to the chain instead of twisting. Supplied on a 16.5 inch cable chain. Choose your letter and your gold colour. Every letter is one stone, 1 carat, E-F color, VS-SI clarity, 3 grams of 14K gold, chain included.
