Gem Information

Matrix opal is a gem material in which precious opal (or play-of-color opal) is intimately distributed through its host rock. The precious opal can occur as a "cement" between sediment grains, as replacements of host material, or as infillings of tiny vesicles. Many people call matrix opal "Type 3 Opal".

Limestone is a soluble rock that can be replaced or silicified by the actions of underground waters. Precious opal can form in tiny voids within the limestone. It can also form as groundwater dissolves some of the limestone, and immediately precious opal precipitates in its place. This chemical process is known as "replacement" or "silicification".

One of the best-known examples of matrix opal in limestone is the Andamooka area of South Australia. Much of the matrix opal there occurs as small patches of host rock replacement within a light-colored limestone.

Care & Guidelines to keep your jewelry intact & glistening


Jewelry is designed to last for many years to come but all precious jewelry will naturally tarnish and look dull if proper care have not been taken. Always protect your jewellery from knocks, scratches, chemicals, sunlight and heat/cold to minimize these effects.


• Remove jewelry when showering or bathing. This is particularly important when on the beach, in the sea and in chlorinated water.

• Avoid wearing jewelry when doing physical work such as housekeeping, gardening or exercise.

• Never expose jewelry to household cleaning products, especially bleach and highly reactive solutions.

• Avoid spraying perfume, hairspray on the gemstones or pearls as it jeopardises the integrity of the material.

• Remove jewellery when applying make-up, creams to avoid the residue getting into the texture or gemstone setting.Any residue dulls the shine of your ring.

• Keep away from extreme temperatures and humidity.
