SEEOUR RANGE OF CUT AND POLISHED OPALS

We started to cut opals as a hobby in 1965 but, within two years, we had opened a gem cutting school teaching the art of opal cutting to hobbyists.

From 1967 onwards, we also supplied all the opal and opal matrix to John webster Industries for their product 'Dig Your Own Opal'.

As a result of the Gem Cutting School, we built up a good clientele for all types of opal and dealt in opal rough, cut opals and also opal specimens. We exported opals to the USA and opalised shells to Japan from 1969.

The growth of our business was mainly due to our skills in opal cutting and over the next few years we traveled to the opal fields of South Australia buying rough opal and selling cut opals, mainly triplets, to the shops on the opal fields.

However, in the beginning, our main business was in solid opals and doublets but we were one of the first business to sell 'triplets' and these proved popular on the opal fields and this area of the business expanded.

If you are not in the opal industry, you may not be aware of the many varieties of opal and it's occurrence. Opal occurs in many different types of rock and has been know to 'replace' other minerals and fossils.In the case of opalised shells, the calcium remains of mollusks are etched away and the cavities, left by them are filled with opal.

See Formation of Opalised Shells and Opalised Fossils

The varieties of opal which may be commonly encountered are opal potch, potch and colour, common opal, precious opal, which includes the variety of opals such as black opal, grey opal and crystal opal. These names apply mainly to opals found in South Australia and New South Wales.

Queensland opal may be called boulder opal or boulder matrix opal but sometimes a place name may be used to describe a particular type of boulder opal such as 'Yowah Nuts'.

When cut, the Queensland opal can be quite beautiful with it's dark ironstone matrix enhancing the opal colour.

However beautiful it may be, boulder opal is typically a 'natural doublet' which refers to a thin slice of precious opal being naturally attached to either potch or some other material backing such as can occur in South Australia on sandstone or quartzite.

Other terms used on the opal fields include, white base, grey base, jelly opal, opal matrix and opal nobbies.
