Gemology: Gemstones Beginning With U...

Can you think of any gemstones beginning with U? It's not easy! There are very few gemstone quality minerals beginning with U, and most of the names you would come across are regionally alternative pseudonyms of other minerals, such as Ugrandite and Umbalite being forms of garnet, and Utahlite a form of Variscite found in Utah, but we have managed to find you a few gemstone quality minerals to continue our gemology guide with gemstones beginning with U.


Unakite is a form of granite found in the Unakas Mountains in North Carolina. It's a naturally occurring blend of feldspar, epidote and quartz. Unakite occurs in shades of mottled green and pink and when polished into beads or cabochons for jewellery use it's considered a semi-precious stone. It's not a particulary durable stone and so it's generally used in jewellery pieces that won't suffer much impact, such as pendants and earrings.

Uvarovite is a rare variation of garnet occurring as a sparkly bright green crystal. It was first identified in 1832 and named for Russian statesman Count Sergie Semenovitch Uvarov. It's not highly durable but it is most definitely pretty and makes for a stunning jewellery piece
