Madagascar Sphene & Cambodian Zircon Mens Signet Ring in Platinum over 925 sz 12

The fire in this gemstone is exceptional. The dispersion (fire) is one of the greatest of all gem materials and is higher than diamond. Because of its high dispersion and refractive index a well cut Madagascar sphene can display stunning brilliance. When Madagascar sphene is cut accurately it shows its fire and luster to its full glory.  In addition to its extraordinary fire sphene displays strong pleochroism meaning it appears different colors when viewed from different angles. Sphene typically displays three colors: colorless yellow-green and red. This trichroic property makes it difficult to pin down the exact color of this stone. Most sphene contains some inclusions; clean pieces are very rare. Stones weighing more than one carat are in especially high demand.  This men's ring is heavy in silver at almost 8 grams of Platinum coated silver to retard tarnishing.
