Zircon Crown recutting. Weight after: 2.07 ct Wei $Zircon Crown recutting. Weight after: 2.07 ct Weight before: 2.17 ct Measurements: 7.32 x 4.70 mm Giving this gemstone a crown with better symmetry, proportions and polishing. It looks much better for years to come. Although colorless when chemically pure, zircon is typically yellow-brown to brown. One of the most typical features of zircon is the high double refraction. It will show clear doubling of pavillion facets in faceted stones when viewed through the crown. Colorless Zircon is known for its brilliance and flashes of multicolored light, called fire. These Zircon properties are close enough to the properties of diamond to account for centuries of confusion between the two gems. Zircon is a mineral species that can be broadly defined as a zirconium silicate containing trace amounts of the radioactive minerals hafnium, uranium and thorium. Over time, these radioactive components break down the lattice of the crystal, eventually (over tens of thousands of years) destroying the internal crystal lattice and leaving it with an amorphous structure and a dark, pithy appearance. #södermannagatan #södermalm #sofo #zircon #smycken #ädelstenar #faceting #gemstone #gemstones #jewellery #gemcutter #recut #repair #lapidary #faceter #stenslipare #guldsmed$
