Variscite Rings: Your Ultimate Accessory for Making a Fashion Impact There are variscite specimens that exist with a white mineral called Crandallite – in these specimens, the Crandallite mineral is formed within the variscite crystal or on top of it – and this combo is highly desired by jewelers who cut these specimens into cabochons. On the Moh’s Scale, this stone ranks between three to four, which is why it’s a fairly soft stone – this is why when you go out to purchase a Variscite Ring, ensure that it is set in a protected setting like the bezel setting or the prong setting in which the stone is tightly secured. A fun fact: the variscite variety that is mined in Utah is fluorescent, and this is why it is highly prized by collectors.
