Worn at the base of the neck, this green amethyst collar necklace fans out across the collarbone instead of hanging in a straight line. Square-cut green amethyst, also called prasiolite, sits in a graduated row, each stone in its own hand-fabricated frame of recycled 14k gold-filled, and concave-cut olive prasiolite beads add contrast and shimmer between them.

If a collar has ever drooped on you or stood stiffly away from your neck, here is how this one was made to sit. The framed stones hang from triple strands of fine chain accented with labradorite, and the length of chain between each framed stone was adjusted by hand so the collar gently fans out when worn rather than drooping. Small cat's eye moonstone rondelles anchor each frame at its sides, holding the stones steady without making them rigid.

The gold-filled frames carry a bonded layer of real gold far thicker than plating. It was made to be worn alone with a scoop neck or a crisp white shirt open at the collar, or with the matching green amethyst stud earrings.

There was only ever one, made by hand by Andrea Li in her Denver studio: for the one statement piece in a pared-back wardrobe.

This piece has found its home. If it speaks to you, I can make something in its spirit.

Put it on with an open-neck shirt and this pastel multi-strand statement necklace becomes the whole outfit: layers of 14k gold-filled chain across the collarbone, broken at intervals by one-of-a-kind clusters of Australian opal, kunzite, morganite and pearls.

The palette runs through green amethyst, aqua hydro quartz, mystic prehnite, moonstone, yellow and blue aquamarine, spinel, topaz, Japanese Akoya keshi pearls, and green and gray sapphires, every stone set on recycled 14/20k gold-filled components along 14k gold-filled sequin and circle link chains. No single stone is the hero; the color is.

If a multi-strand necklace has ever bunched or gapped on you, here is what Andrea did about it. Each layer of chain was measured for its own drape across the collarbone and chest, and the clusters sit at intervals chosen so the strands flow instead of piling up. At the back, a gemstone cluster rests at the nape of the neck, a detail mostly you will know is there. The opal and the pearls are the delicate elements, so the whole necklace is cold-connected, assembled with wire and never with heat.

One necklace, made once by Andrea Li in Denver and never repeated: for the collector who wants a piece no one else owns.

Akoya keshi pearls against mystic quartz, sculptural amethysts beside baroque pearls: this multi-chain gemstone drop necklace is built on contrast, with a one-of-a-kind abstract cluster at its heart, 18k gold vermeil leaves, and strands of recycled gold-filled chain that fall into an asymmetric drop.

Color leads the composition, not any single stone. The palette runs through pale amethyst, hydro quartz, Australian opal, moss aquamarine, aquamarine, ametrine, spinel, morganite, moonstone, topaz, kunzite, purple sapphire and mystic labradorite.

If an asymmetric necklace sounds like one that hangs lopsided, the asymmetry here was planned, not left to chance. Andrea assembled each section by balancing its weight, color and shape against the others, on recycled 14/20k gold-filled components with the vermeil leaves and chain, so the drop and the cluster sit where she placed them.

It was made to be worn on its own over a plain neckline, or with a gemstone cuff bracelet or companion earrings.

Made once by Andrea Li in Denver and never repeated: for anyone who would rather own one remarkable piece than a drawer of safe ones.

The first piece made for the Tamar collection, this pastel gemstone statement necklace is a one-of-a-kind asymmetric design on sequin and diamond-cut 14k gold-filled chains, with a Biwa pearl chain running through them.

Kunzite, mystic quartz, amethyst and gray sapphires gather at the center in an asymmetric flourish, and shimmering Australian opals sit along the chains. Pale amethyst, aquamarine, zircon, mystic labradorite and purple sapphire fill out the palette.

If "gold chains" makes you ask whether this is real gold, here is what it is made of. The sequin and diamond-cut chains and the Biwa pearl chain are 14k gold-filled, a bonded layer of real gold far thicker than plating, and the components are recycled 14/20k gold-filled. The 18k gold vermeil elements are gold over sterling silver, never over base metal.

It was made to be the only necklace you wear, over a plain neckline.

A concave-cut green amethyst at the end of a long drop is the point of this pastel gemstone drop necklace, a one-of-a-kind pendant on recycled 14k gold-filled paperclip and circle link chains. Its curved, scalloped facets catch the light as you move.

Above it, blue topaz carries the line down from a cluster of Japanese Akoya keshi pearls, Australian opal, yellow aquamarine, aquamarine, kunzite, pale amethyst, mystic quartz, and purple and gray sapphires, with gold U-shapes on either side.

If a cluster this full makes you wonder whether it will look busy, the palette is the answer: watery blues, soft greens and pale violet, every stone chosen for how it sits beside its neighbors rather than on its own. After living with the finished piece, Andrea added one slice of Australian opal with soft blue flashes to close the last gap in the cluster. Two more topaz sit where the chain turns around the neck, so the design carries all the way to where the necklace disappears from view.

Wear it with a crisp white shirt or a scoop neck, where the drop has room to fall.

Made once by Andrea Li at her Denver bench and never repeated: for the woman who leads all day and still wants to feel feminine.

Turn your head and the chains of this green amethyst tassel necklace move with you: a long fall of 14k gold-filled sequin chains, anchored by a vertical stack of faceted green amethyst. The flat, disc-shaped sequin links catch light in small flashes, and black and gold link chains add a darker sparkle through the drop.

The worry with any chain tassel is that it twists, drifts or knots instead of hanging cleanly. Here the green amethyst does that job. The stones give the sequin chains their downward pull, so the chains hang in a straight vertical line, the tassel falls with intention, and the drop keeps a clean line down the decolletage. The jump rings and clasp are recycled 14/20k gold-filled, a bonded layer of real gold far thicker than plating.

It works with an open neckline or over a high collar, minimal in shape and dramatic in motion. The Green Long Gemstone Tassel Earrings are its companion pair, the same sequin chain and green amethyst at a smaller scale.

This necklace is part of Andrea Li's pastel gemstone jewelry, and it exists once.

Three chains that hang as one, without a twist, are the whole trick of this green amethyst Y-drop necklace. Framed green amethyst, also called prasiolite, falls in a single line down the center of the chest, and above it three 14k gold-filled sequin chains rise toward the neck, splitting as they climb while still reading as one strand.

If you have worn a multi-chain necklace that tangled or sagged out of line by lunch, here is what keeps this one together. On each side, all three chains are anchored to a small concealed metal bar, curved to follow the contour of the neck, so no chain droops lower than the others. Each stone sits in its own custom gold-filled frame, precision-drilled and joined to the next with soldered jump rings, so the cascade hangs straight and moves as one piece.

The chains and components are recycled 14/20k gold-filled, a bonded layer of real gold far thicker than plating. The drop starts below the collarbone, made for a V-neck, an open collar or a plain black top, and the Green Long Square Gemstone Drop Earrings echo it with the same square-cut green amethyst in gold-filled frames.

It belongs to Andrea Li's pastel gemstone jewelry, and like every piece there it is built once and never repeated.

Engineered by hand in Andrea Li's Denver studio and made only this once: for someone who wears jewelry as art, not as an accessory.

There is only one of this gold paperclip chain necklace with a baroque pearl: a single lustrous baroque pearl anchors a pastel gemstone cluster that serves as the connector in a chain of elongated 14k gold-filled paperclip links.

The cluster is a palette of its own: aquamarine, rose quartz, kunzite, morganite, amethyst and green amethyst, with Japanese Akoya keshi pearls, Peruvian opal, and green, purple and gray sapphires. The hook is forged by hand, and every component is 14k gold-filled or recycled 14/20k gold-filled.

If paperclip chain makes you think of a trend piece that tarnishes in a season, here is the difference. These chains are 14k gold-filled, a bonded layer of real gold far thicker than plating, made to wear for years rather than months. The baroque pearl and the cluster do the rest: a modern link chain with a collector's center.

It wears as a statement collar, easy with a white shirt or a bare neckline.
