About Marianovich Gems

Marianovich Gems is a premium gemstone house specializing in rare natural stones with exceptional origin, individuality, and presence. Our flagship selection highlights remarkable Russian gemstones—alexandrite, demantoid garnet, emerald, and sapphire—chosen for their character and true collectible appeal. We also present select Ukrainian aquamarines and heliodors, valued for their refined color and luminous elegance.

Beyond our core specialties, we offer rare sapphires, rubies, and emeralds from some of the world's most celebrated deposits, alongside museum-worthy collector specimens—pieces acquired for those who value rarity, story, and authenticity as much as beauty.

Our approach is intentionally selective: we do not chase volume—we curate. Each gemstone is evaluated individually for color, cut, clarity, and "life," with transparent disclosure of origin and any treatments. When available, stones are supported by documentation and leading lab certification (e.g., GIA/GRS/IGI).

Above all, we believe our work is not simply to sell gemstones, but to make clients genuinely happy—through trust, guidance, and finding the one stone that feels unmistakably right.
