Danburite is not widely known, but its an excellent gem. With a hardness of 7 and an RI that ranges from 1.627 to 1.639, it cuts beautiful stones have excellent brilliance and flash. This gem hails from Mexico, a source of some beautiful colorless and pale pink Danburite. This gem is a very pale pink, although it’s almost impossible to see the color, except on a stark white background and at an angle. Instead it appears to be colorless and very brilliant in the hand.
I faceted this Danburite in my custom “Hyperbola” brilliant oval design, optimized for the RI of Danburite. The gem weighs 10.45 carats and measures 15 x 12.7 x 9.5 mm.
