Do the photos accurately portray the opals?

We do our best to photograph and capture the realistic colour and details of the opal stone accurately, however, opal can appear different depending on the lighting and its surrounds, and the device used to encapsulate its beauty.

Most of our items are photographed in a light box and some in natural light with or without a macro lens, via a mobile phone or digital camera. As all computer monitors, device screens are different, there may be slight differences in the colour of the item upon receiving it, as to viewing it from photos.

What is opal?

One of the most exquisite and valuable gemstones, opal is mostly found in Australia. It is one of only six varieties of valuable gemstones discovered in the world, standing in illustrious company with pearls, diamonds, rubies, sapphires, and emeralds.

What are solid opals?

Opals that have only undergone the cutting and polishing necessary to transform them into gemstones.

What are doublets?

Is a composite made of two layers, with a thin coating of crystal opal on top and a dark stone on the bottom.

What are triplets?

A clear crystal dome is placed on top of a paper-thin slice of opal that is adhered to a black stone backdrop.

What are black opals?

Black opal possesses a body tone or background that is either black or extremely dark grey. The opal colours and pattern will shine out more, enhancing the stone's beauty, the darker the body tone.

What are dark opals?

Dark opals consist of a darker or greyish body tone which isn't considered black, white nor crystal. 

What are white opals?

White opals have a whitish tint to the body. A white opal base showcases the colours and patterns of the opal.

What are crystal opals?

If opal is completely transparent or translucent, it may appear as though you are staring through glass. Black, dark, or white are the three body tones that crystal opal can have.

What are boulder opals?

Boulder opal is made from either sandstone or ironstone with a seam of opal that formed inside the boulder.

What are matrix opals?

Opal that is found as a network of veins, filling of spaces, or in between host rock grains is known as matrix opal.

What are fossilised opals?

The remains of former life that are preserved in rock, soil, or amber are called fossils. These might be the remains of different extinct animals, dinosaurs and plants. Opalised fossils form similarly to other fossils, with the exception that silica is used to preserve them. Like other fossils, fossilised opal takes millions of years to develop and are considered rare and precious. Unlike normal fossils, fossilised opals may have a polished finish on one side to expose their colour quality.

Why are some doublets or triplets more expensive than some solids?

Generally, solids are more expensive than doublets or triplets, however, in some cases, a doublet or triplet might be more expensive than a solid due to their levels of quality. The quality depends on the strength of colour and the size and cut of the stone.

What is inlay?

Inlay is when a custom cut stone is painted black on the underside and is set with glue in an unfilled piece of jewellery. The result is a finished product where the stone is level with the jewellery piece it is set in. This technique reveals a vibrant, contemporary look which is appealing to the viewer's eye. Inlay is an intricate and delicate jewellery design technique that needs to be performed by an experienced cutter and expert jeweller.
