Taaffeite Is A Rare Gemstone

Taaffeite is one of the rarest gemstones in the world. It was first discovered as an already cut, polished, and misidentified "spinel" in a Dublin, Ireland jewelry shop by gemologist, Richard Taaffe who bought a cluster of gems in October 1945.

Taaffe noticed some inconsistencies in his "spinel" and sent a sample of the stone off to a London lab which in 1951 verified that its main components were beryllium, magnesium, and aluminum, making the hexagon crystal a newly found mineral later named taaffeite (BeMg3Al18O16).

Unlike spinel, which is only singly refractive (like diamonds and garnets)Taaffeite is doubly refractive (it blends and reflects light in all directions). Taaffeite is a transparent gemstone with a vitreous shine (like glass in appearance or physical properties).

This beryl forms in carbonate rocks in Sri Lanka and Southern Tanzania (alongside the gemstones fluorite, mica, spinel, and tourmaline). Some poor-quality taaffeite has also been discovered in China. 

Because of its rarity, taaffeite is only used as a gemstone. Registering an 8 - 8.5 on Moh's Scale of Hardness, the jewel comes in colorless, violet red, pink violet, red, light green, and mauve. Taaffeite costs an average of $1,500 - $2,500 per carat, although top-grade taaffeite can fetch $35,000 per carat. The best quality taaffeite gets bought quickly. Pink is the rarest and most expensive color.


This beryllium-magnesium-aluminum-oxide mineral is clean of inclusions, and the red is gorgeous. Imagine ... a jewelry lover wearing it would bling all over the place!

Have you ever heard of taaffeites?
