Smoky Quartz 925 Silver Necklace

About Smoky Quartz :-
Smoky quartz is a brownish grey, translucent variety of quartz that ranges in clarity from almost complete transparency to an almost-opaque brownish-gray or black crystal.[6] Like other quartz gems, it is a silicon dioxide crystal. The smoky colour results from free silicon formed from the silicon dioxide by natural irradiation. Smoky quartz is common and was not historically important, but in recent times it has become a popular gemstone, especially for jewellery. Cairngorm is a variety of smoky quartz found in the Cairngorm Mountains of Scotland. It usually has a smoky yellow-brown colour, though some specimens are greyish-brown.
