Some information about the Opals Of Indonesia

Most people don’t know it but Indonesia produces some of the most beautiful opals in the world – although still in very small quantities. The opals are all of volcanic origin and just about every type of opal exists here, the main types being:

1. Milky white and crystal white opals, similar to Australian opals.

2. Boulder opal, similar in appearance to Australian opals but the base rock (the “boulder”) is a different type of stone.

3. Glassy white and tea-colored opals similar in appearance to Mexican opals.

4. Black [often referred to as “Java Black”(this term is actually our creation)] opals, a sepia to jet black opal often with a deep red play of color, somewhat similar to Nevada opal (Australia very occasionally produces stones like this as well).

5. Hydrophane opal, a remarkable opal that has little or no play of color when wet, but is perhaps the brightest of all opals in the world after cutting, polishing and being thoroughly dried. Hydrophane opals also exist in Australia but they are just the opposite – dull when dry but with a beautiful play of color when wet (unfortunately for the Australians you cannot keep your ring wet all the time!). Hydrophane opals can be white, a golden yellow, gray or brown, dark olive green or even jet black – of course the jet black stones with the amazingly bright play of color found in hydrophane stones are the most sought-after opals from Java, and are one of the most beautiful opal types in the world.

The opals of Java have been written up by Irwan Holmes in the American magazine, Lapidary Journal (copies of the article are available from Dharma Mulia Galleries), June 1986.

One of the great investment opportunities in Indonesia is the mining of opals. We have 11 hectares of opal-bearing land for investment. For further information contact us at dmulia@cbn.net.id.
