White Opals

Introduction to Australian Opal Cutters

Natural White Australian Opals that have been hand cut from rough Opal in the Australian Opal Cutters Sydney workshop. This is the perfect gift as it an Opal an investment and the only gemstone where you can "hold a rainbow in your hand" literally! 

"Loose" Opals or "un-set" Opals are Opals that have not yet been set into a piece of Jewellery. These Opals are hand-cut from the "rough" material by industry experts who know how to find the colour and carefully remove the Opal "potch" (Opal without colour). This is an age-old tradition and is a cutting process that has not changed in 100 years.

Each Opal you will see on this site is completely natural and had not been treated or enhanced in any way, shape or form (unless specifically noted in the description).

Opal is Australia's National Gemstone and is the only gem in the world where you can hold a rainbow in your hand (literally)

Rainbow colour appear in may places and materials. Through faceting a diamond we are able to split light into the colours of the spectrum. Through different checmicals, or treatments we can make certain gems show rainbow colours...but did you know that there is only one place on earth where rainbows actually form and can be held? This is in Opal.

Opal is absolutely unique as tiny microscopic water molecules actually bond and merge with silica to form a gemstone (Opal) this process is so mysterious that scientists still ccannot tell us why it happens. The result is that microscopic rainbows actually form inside the gem. They are "trapped" or held there in suspension, and will not evaporate (like a rainbow in the sky does).

This is a "miracle from the ground" so now you can "Hold a Rainbow"!

Technical Specifications

Genuine Natural Australian White Opal from Coober Pedy in South Australia. A hydrated amorphous form of silica SiO2·nH2O consisting of spheres of silicon dioxide molecules arranged in regular, closely packed planes. Magnesium Oxide gives the Opal a white base and opacity. Precious opal shows a variable interplay of internal colors, and though it is a mineraloid, it has an internal structure. At microscopic scales, precious opal is composed of silica spheres some 150 to 300 nm in diameter in a hexagonal or cubic close-packed lattice. It was shown by J. V. Sanders in the mid-1960s that these ordered silica spheres produce the internal colors by causing the interference and diffraction of light passing through the microstructure of the opal. The regularity of the sizes and the packing of these spheres determines the quality of precious opal. Where the distance between the regularly packed planes of spheres is around half the wavelength of a component of visible light, the light of that wavelength may be subject to diffraction from the grating created by the stacked planes

Guaranteed free of dyes and artificial colour.

After doing research on the best place to buy opals in Sydney I decided upon Australian Opal Cutters. It is off the tourist trap, no fancy marketing, a strange shop on the 3rd floor of a building with top security to get in and out and therefore not paying premium rates to cover the cost of the premises! Expert knowledge, a huge selection of beautiful opals and felt happy with the quality and authenticity of the opal pendant that I purchased. Added bonus was a pair of pearl earrings as a gift and a nice bottle of red wine. Would recommend

I had bought an Opal ladies watch last year, the glass had come off, (it was rarely used) visited them this year for a possiblity of getting it repaired, they had my records in their customer database - had to leave it there for rectification.
They called me next day and told it was done and I can collect it.
Went there and found it was not working (when I had given them it was in working condition)
They were surprised like me and offered a new one, a bit more expensive as the same type was unavailable at no extra cost
The staff were very courteous, they have good variety of jewellery
Will definitely buy from them whenever I'm in Sydney

I was on a quest to find an opal to take home to my wife in US. Having visited another recommended opal store and getting a rehearsed sales pitch, it was refreshing to visit Australian Opal Cutters and Pearl Divers. If you are looking for a high end boutique appearance, this is not the place. If you are looking for honest answers and advise, you have found the right store. After being shown the difference types of opals in both appearance and quality, I was able to choose a beautiful black opal pendant with brillant streaks of color. I was pleased with the cost and my wife was very pleased with my choice.

Vern and I stopped in at their 3rd floor shop on Pitt St. I had a pair of rough opal earrings that were mounted improperly years ago and one stone wore through the hole. I've been wanting another pair. We worked with Jason Blaiklock, managing director and he set us up for a lot of fun and searching. One jar at a time he brought out his rough opals. We found the right size stones, different jars. We'd work through, I found the first stone. Re-bottle all the others and another bottle came out. I have to say he's never had a customer looking for rough stones and when he saw my choices he had to fight the urge to polish them to bring out that luster of color. We chose the settings and he told us how they mount the stone so no holes are drilled through which is much safer for the stones. I love them!!!

Saw on the Free Tour Map (didn't do it, just took the map at the meeting point, Town Hall if I recall correctly) that if you bring that map to Australian Opal Cutters, you'll get a free workshop on Opal cutting and a free pair of pearl earrings. Unfortunately the cutter wasn't there when I went but the lady was still very knowledgeable and explained to me the cutting process while showing me the equipment. She also explained to me the differences between the various shapes and colors of opals/pearls. I also got to get home with my own free pair of pearl earrings that completed very well my outfit for the Sydney Opera House the next day! Of course they will try to make you buy something but they won't insist. And if you are genuinely interested in knowing more about opals and pearls, I definitely recommend it! Plus, free pearl earrings! Great souvenir or if you are a guy, it makes a great gift for that special lady in your life ;)
