Frequently Asked Questions

Everything you need to know about tanzanites.

What makes tanzanites a good choice for jewelry? +

Found in only one place on Earth — the foothills of Mount Kilimanjaro — tanzanite is a thousand times rarer than diamond. Its mesmerizing violet-blue shifts with the light, displaying flashes of burgundy and purple. A once-in-a-generation gemstone, independently certified. Every tanzanite in our inventory is independently certified and can be set in any of our rings, pendants, earrings, or bracelets.

Are your tanzanites certified? +

Yes. Every gemstone in our inventory is certified by an independent gemological laboratory — including GIA, GRS (Gem Research Swisslab), and Gübelin. Certificates document color, clarity, carat weight, treatments (if any), and origin. Learn more in our gemstone grading guide.

How do I choose the right color and clarity? +

Color is the most important factor for colored gemstones — look for vivid, saturated hues without being too dark. Clarity matters less than in diamonds; most colored stones have natural inclusions that do not affect beauty. Use the filters above to narrow by color intensity and clarity grade. Our gemstone color guide covers this in detail.

Can I set this gemstone in a custom ring or jewelry piece? +

Absolutely. Every loose gemstone can be set in any of our jewelry settings — choose from 14K gold, 18K gold, or platinum in yellow, white, or rose. Contact our team for a custom design consultation. We specialize in one-of-a-kind pieces built around exceptional stones.

What is the difference between natural and treated gemstones? +

Most gemstones undergo some form of treatment to enhance color or clarity — this is standard practice and disclosed on every certificate. Common treatments include heat treatment (sapphires, rubies), oiling (emeralds), and irradiation (topaz). Untreated stones of fine quality command a significant premium. Every stone in our inventory includes full treatment disclosure.

Do you offer free shipping and returns? +

Yes. Every gemstone order ships free with full insurance via a secure, trackable carrier. We also offer a 30-day money-back guarantee — if you are not completely satisfied, return your purchase for a full refund. Learn more about our return policy.
