3.25 ct. 'Pink Fire' Quartz with Covellite
Color: Very Light Brown

Origin: Brazil

Measurements: 9 mm
A very fine example of one of the most interesting Quartz inclusion gems in the market. From Brazil comes this Quartz with platelet-type inclusions of the mineral Covellite. What is truly phenomenal about this particular combination is that while Covellite is metallic in transmitted light, it has a bright pink flash in reflected light - so, as you move the gem a strong pink flash moves across the surface. A very unusual and attractive natural effect. Not surprisingly, gems from this locality have been given the name of 'Pink Fire' Quartz - an apt trade name.
The orientation of the flash and cutting are both particularly good in this stone - the pink flash is not at all hard to elucidate and generally moves across the entire surface. Moreover, we have found that examples with a very light smoky bodycolor show the flash to great contrast. Much of the find was nowhere near as nice with many stones moderately included with wispy veils.
