Blue Gem Turquoise

Lander County, Nevada

A historic Nevada mine known for hard stones, deep colors, and tight matrix.

Where it comes from

Blue Gem turquoise was first mined commercially in the early 1930s in Lander County, Nevada. The mine produced steadily for several decades and remains historically significant in American turquoise. Active production has been intermittent for years, which makes genuine Blue Gem cabs increasingly hard to source.

What makes it distinctive

Blue Gem is notoriously hard, which makes it durable in everyday jewelry but also more challenging for cutters. Colors range across electric blue, deep teal, and rich green, often with distinct gold or brown matrix. The hardness gives the finished cabs a brilliant polish that holds up across decades.

How to identify it

Look for the unusually high luster and depth of color. Blue Gem doesn't have a single signature look because it produced across a wide color range, so trust comes from provenance and seller reputation. The stone should feel dense and substantial for its size.
