However, the production has been and still is very low, and the rough is only found and offered very seldom and in very little quantities. The brilliant shades of green of the transparent Tanzanian Green Opal range from the delicate green of spring to a bright apple green through to a deep dark green. Fine traces of nickel from weathered serpentine are the cause of the color of the Tanzanian Green Opal.
It is said that the intensely bright, invigorating Tanzanian Green Opal has the power to raise the mood and to bring serenity and joy to our lifes.
