If you’re in the market for classic faceted gemstones or artisan-cut specialty gemstones, we have high-grade natural gemstones like rubies, emeralds, sapphires and specialty gemstones like Glenn Leher’s TorusRing™ and the Vortex™ cut by Sherris Cottier Shank. We also have a vast selection of manmade faceted gemstones like moissanite, cubic zirconia (CZ) and simulated birthstones.
Rio Grande is also a great resource for cabochons, cameos and pearls. We have over 300 types of cabochons, including natural stone, crushed and simulated block stone for inlay work and a variety of other manmade and natural options. We also carry a wide variety of agate cameos—several of which are replicas of the famous works of Art Nouveau artist Alphonse Mucha.

And for a real treat, shop our handcarved Galatea pearls in a variety of captivating designs.
