Four colors live in this stone. Teal, cyan, amber gold, and pale celery green ribbon through near-black chert in a diagonal cascade that looks less like geology and more like a desert skyline captured in mineral. Blackjack turquoise is already rare — a stone with this much color variation and movement is the kind collectors recognize immediately.

The oval cab is set in a fine silver bezel with an inner raised gallery, mounted on an oxidized sterling backplate with small granule details flanking the lower right of the setting. A clean, elegant frame that knows when to step back. The piece hangs from an oxidized wheat chain, the warm dark silver picking up the near-black of the matrix and tying everything together. The back is finished with a polished sterling backplate stamped with the maker's mark and .925 hallmark.

One of a kind. Made in my Fort Collins, Colorado studio. Ready to ship.

This pendant has a matching ring — shop the Blackjack turquoise ring and use code BLACKJACKSET at checkout to save 10% when you purchase both.

Note: This stone has a minor surface fracture visible under direct light. It is tight, stable, and fully secured in the bezel. Several listing photos show it clearly.

✦ Packaging & Shipping

Arrives in a Silverthaw Jewelry gift box, ready for gifting or keeping. Ships in 1–2 business days.

✦ Care

Turquoise is a natural, porous gemstone. Avoid lotions, perfumes, and prolonged water exposure. Polish silver gently with a soft cloth as needed. Polishing cloths will remove intentional patina, so take care not to over-polish.

✦ About Blackjack Turquoise

Blackjack turquoise comes from a small Nevada deposit known for dramatic contrast and vivid, naturally formed matrix. Unlike uniform blue turquoise varieties, Blackjack ribbons brilliant blue-green through deep brown to near-black chert, often with iron-gold tones alongside — creating a polychromatic pattern that makes every stone a completely singular painting.

Much of the finest Blackjack on the market today is mined and cut by the Otteson family, who have worked Nevada turquoise claims for generations. Their careful lapidary work preserves the natural drama of each stone: the wild matrix, the vivid color, the bold character that makes Blackjack a collector's variety.
