Prase opal is a nickel-bearing variety of common opal, with nickel being the chromophore that illuminates the neon bluish-green hue. Chrysoprase and prase opal can be similar in appearance but can easily by separated by varying RI and SG. Both varieties range from low-quality opaque material to high-quality translucent jewels; however, the prase opal tends to be more translucent and gemmy.

Chrysoprase and prase opal have been mined on Iyobo Mountain in central Tanzania for more than 20 years, with the first accounts being described by Gübelin in 1975. The most recent discovery revealed some of the most intense and beautiful bluish green material to be seen by the gem trade. The majority of the production is in the chrysoprase form, while the prase opal is the more rare find from this deposit. Chrysoprase and prase opal both form in discontinuous veins within metamorphosed ultramafic rocks with the most dominant host rock being altered serpentine.

VOLCANIC OPALS is run by Paul sedawie of Seda Opals.The Seda Opal company was incorporated in 1994.The owner Paul sedawie is the current president of the OPAL ASSOCIATION INC .Seda Opals is an abbreviation from our surname Sedawie. The business is mainly wholesale and it is through this site that we can bring the opal fields and the bargins direct to you. Paul Sedawie started mining at the Four mile field in Lightning Ridge in 1986 with his first partner Bob Young. It took them 6 months to find a decent stone and this experience gave me a healthy respect for the stone and how hard it is to find. Previous to mining opal, Paul ran a successful mail order business in plants for 7 years which gave him a lot of experience servicing customers through parcel post. We use mainly Australia post as it has a excellent reputation for delivery to most parts of the world. I don't do any active mining now but my eldest son Peter Sedawie has taken over. This leaves me free to travel to any opal field in the world and to enjoy the beauty of this magnificent stone. We hope you enjoy our stock and good luck with your biding We have a retail shop/museum at the Gold Coast Opal and Gem Centre 25 surfers av mermaid waters Qld Australia .4218 open mon to sat 10 to 5
