One of a Kind Necklaces, Led by an Award Winner

One necklace here holds the AGTA Spectrum Award for Excellence in Evening Wear, the American gem trade's design prize. The rest of the collection keeps that company honestly. Blue labradorite butterflies with articulated wings, in four sizes. A tennis necklace of fifty-three opals, each cut to its own free shape. Zambian emerald on a bezel line and on a diamond rolo chain. A sugarloaf strand of citrine, amethyst and topaz cut into smooth pyramids. Rainbow sapphire, and forty-six yellow and orange sapphires on one strand. South Sea rose pearls. Hand-carved orange shell and pink coral on a link chain. Each is a single find and a single build, set once in 14K or 18K gold, and when one sells the collection changes shape. That is the deal, and the reason to keep coming back.

One of a Kind Necklaces: Frequently Asked Questions

Where can you find one of a kind necklaces?

Here, for a start. Every necklace on this page exists once, designed in Newport Beach around a stone or a matched suite we will never see again, and retired the day it sells. The page changes as pieces find their owners.

What is the AGTA Spectrum Award?

The American Gem Trade Association's annual design competition, among the most respected prizes in colored gemstone jewelry. Our Chroma Forme Necklace won the Spectrum Award for Excellence in Evening Wear, and it lives in this collection.

What gemstones are in these necklaces?

Zambian emerald, Ethiopian opal, blue labradorite, sapphire in rainbow, yellow and orange, tsavorite, kyanite, rubellite, turquoise, citrine, amethyst, topaz, yellow beryl, white jade, South Sea pearl, black onyx and hand-carved coral, set in 14K and 18K gold, most with diamonds. The list shifts as stones arrive and pieces sell.

Which pieces are hand-carved?

The listing says so wherever a stone was carved by hand: the orange shell and pink coral link necklace, the largest of the labradorite butterflies, the coral pieces that pass through. Carving is named only where it happened.

How do I care for a one of a kind necklace?

Know the softest stone in it, and we will name it before you buy. Sapphire at 9 on the Mohs hardness scale and emerald at 7.5 to 8 are easy company. Opal at 5 to 6.5, labradorite at 6 to 6.5, pearl and hand-carved coral at 3 to 4 ask for ceremony: on after perfume and hairspray, off with a soft cloth, never an ultrasonic cleaner. A necklace lives a gentler life than a ring, and these stones live happily on one.
