Chrysoprase, a variety of the chalcedony family with the most alluring green colour in nature as a result of the presence of nickel, whereas it is the presence of chromium in emeralds and chrome diopside which gives them their green colour.
Chrome chalcedony was a valued gemstone in the ancient world. Indeed in ancient Roman, this material was used to make intaglios and cameos. On 16 June 2020 this parrot signet ring which was listed as "A Roman gold and green chalcedony finger ring with a parrot, circa 1st century BC-1st century AD" was sold for $87,500 at Christie's Auction.
Chrome chalcedony has been known to come from present day Turkey in Roman times.
Chrome chrysoprase comes from Mutorashanga, Zimbabwe and it is locally known as "mtorolite". What makes mtorolite rare and special is that it gets its lush green colour from nickel and small amounts of chromite.
You may well be confused as to why its called "chrome" as oppose to "nickel" chrysoprase. Quite simple, its all down to marketing, "chrome" is just more widely known then nickel!
Chalcedony continues to be used for carvings and for healing. Its metaphysical properties include calmness and quietness, these positive attributes are especially welcome when the mind is too busy, active and anxious.
Mtorolite is not devastatingly beautiful in the way an emerald or chrome diopside is, its green has a particular tone of tranquility, it has a cooling, soothing freshness. If you pick up a piece of mtorolite and gazed at its green colour, the effect would be the same as when you apply aloe vera or cucumber to the eyes. In turn, this would have the same effect on your mind, quietness, calmness and tranquility.
