Here is one that you certainly don't see everyday.  Extremely rare as a gem material, Prosopite typically forms only very small, colorless crystals.  However, at a deposit in Zacatecas, Mexico the mineral occurs as this unusual blue material that bears a startling resemblance to the finest Turquoise.  A superb robin's-egg blue, the color is bright and remarkably consistent with just some matrix inclusions as you might expect.  The make of the cab is excellent, a pleasant oval with a fine polish.  This material is extremely limited; unusual, attractive and rare - just the type of piece we enjoy offering.
