Jeremejevite Gemstone Description Jeremejevite (pronounced ye-REM-eh-yev-ite) is one of the world’s rarest gemstones, admired for its exceptional clarity, hardness, and range of subtle colors — most commonly pale blue, colorless, or light yellow. This rare aluminum borate mineral was first discovered in 1883 in Siberia and named after Russian mineralogist Pavel Vladimirovich Eremeev (Jeremejev in German transliteration). Though originally known to mineral collectors, facetable jeremejevite only began appearing in the gem market in recent decades, primarily from deposits in Namibia and Myanmar. Fine-quality transparent crystals are extremely rare and often highly priced, making jeremejevite a coveted gem for elite collectors and connoisseurs.
