Known to First Nations people as ‘the fire of the desert’, opals represent Australia's arid interior where the precious stones develop slowly, over millions of years.
At the Opal and Diamond Factory, our collection of South Australian crystal and white opals, Queensland boulder opals and famous Lightning Ridge black opals is the largest in Australia.
Opal Diamond Factory’s John Ryneš and Mike Saj-Ryneš have been collecting and cutting opals for more than 45 years, and understand how to bring each stone’s hidden beauty to light.
Our ties to mining communities - established over these years - give us access to a stunning variety of exquisite stones.
As an engagement ring, opals are a perfect representation of love and fire within your relationship. No two opals are the same, so when choosing an opal for your engagement ring you truly are getting a one-of-a-kind, original piece.
Throughout much of history, opals were believed to be good luck. The Romans thought that opals were one of the luckiest gemstones and a symbol of hope. Queen Victoria was also a lover of opal, wearing opals throughout her 19th Century reign and owned a fine personal collection. Our family has been dealing with opals for over 45 years and it has brought nothing but good luck to us.
While opals are not as hard as other kinds of gemstones, they are still durable. Opals are about the same hardness as glass. On the Mohs hardness scale, they are 6.5 out of 10.
Look closely at the pattern. An opal created in a laboratory (Gilson opal) displays bright colours in large patches of colour. The pattern is often 'too perfect' and ordered. It can also often display a 'snakeskin' like pattern.
The value of an opal is determined by the colour and brightness of the stone. Following that, we look at the size and weight of the opal. Opal price can very from about $10 per carat to approximately $25,000 per carat.
Black opal with red is the most rare and highly valued form of opal. Black opal naturally has a black (or dark) body tone. Black opals come in every colour of the rainbow, but red is the most elusive and hardest to find.
It takes about 5 to 6 million years to make a 1 cm opal mature. It is believed that 30 million years ago the chemical compound silica was released into a solution which filled cracks in the rocks, layers in clay, and even some fossils. Some of them became precious opals.
Thanks to our history, and the relationships John Ryneš and son Mike have formed with miners over the years, miners come to us directly to sell their rough opal/stones. Our exclusive stone collection has been assembled over decades, and we have stones you just can’t find anywhere else.
Overall RatingIncredibly helpful and friendly staff. Worked with me to create the perfect ring for my partner and it's absolutely stunning.
I have done the research for you, so you can just go ahead and use ODF and not bother looking any further. Exceptional customer service, brilliantly talented and the kind of honesty in sales that is not regularly encountered. We could not be happier with our experience with Mike and will continue to use him in the future! Thank you, Mike!
We finally found the perfect one 💍 an opal engagement ring that we both love! Mike was great to work with and we would highly recommend him to anyone looking for an engagement ring or other jewellery. He was very professional and patient as we looked at a variety of styles and opals.
Wonderful customer service! LGBT friendly - the whole family made me feel very welcome and accepted. The engagement ring was literally perfect, and my Fiancée loves it! I designed the ring and Mike was amazing helping me through the various stages of the ring's creation. We will be back for the wedding rings :) Thank you ODF!
Could not be happier with the service and product. The staff were amazing, gave me a variety of options and talked me through all the steps up front. Our engagement ring turned out absolutely stunning - Thanks again to Mark and the team!
Extremely helpful service with designing a custom ring! Understood exactly what I was after and delivered within my budget and time frame. Would highly recommend!
My engagement ring that i designed for my partner was perfect, great communication from mike, and the way he listened and put in his own thoughts and recommendations as well made the ring just absolutely stunning and jaw dropping for me and my new fiancé, if you are looking for a custom made engagement ring, this is the place. You WONT regret it
From my very first experience at ODF as a child, going into the shop just to browse the beautiful gems with my Mum, they have been nothing short of amazing. I have since bought multiple pieces for my family, all custom designed by Mike. I have been over the moon with every single piece. Mike's eye for detail is spectacular and his craftsmanship is exquisite. My fiancé designed my engagement ring with Mike, going over every fine detail, I love my ring so much. I recommend ODF for all jewellery, whether it be a piece bought in store or a custom piece designed by yourself and mike, I assure you won't be disappointed.
If you are reading these reviews in the hopes of finding a dream piece of jewellery (especially an engagement ring) then your search is complete. Out of all the locations I went to searching for an engagement ring, this was head and shoulders above the rest. A daunting process was made not only easy but enjoyable by the lovely people at The Opal Diamond Factory. They are caring, helpful and above all know what they are talking about. The whole process was made easy by Mike; from the sizing to the style, the stone itself and overall design features, anything seemed possible. I cannot praise this man and his skill enough; the care he puts into understanding what you want the design to say and the jewellery itself is amazing. As for the jewellery itself, it is nothing short of breathtaking. His ability to frame the centerpiece stone while also making the band stand out is phenomenal. For me this involved engraving the engagement band to make it appear as though it was a branch supporting an opal. The detail he was able to achieve with this was amazing. Not only this, but the quality of the opal and the range of choices and styles available will mean that there will definitely be something that catches your eye as ‘the one’. If you are like I was and are searching the internet in the hopes of finding something special, then you have found the location you are looking for. Stop reading this and ring, email or go to the store, you will not be disappointed by the service, care or heart stopping potential that their jewellery has.
It’s rare that you come across a true professional like Mike. Choosing a jeweller was an easy decision for my husband, when the time came to design my engagement ring in November 2019. My husband worked closely with Mike to design my bespoke emerald cut engagement ring, and then 18 months later, I had the pleasure, when it came to our wedding bands. The showroom is warm and welcoming – just like the family that works there, and we instantly felt comfortable, which made it easy for us to discuss our ideas openly and honestly. Mike’s knowledge and experience coupled with his understanding of current trends, is how we were able to create elegant and truly timeless pieces. The process was such a memorable and positive experience and I would highly recommend Opal Diamond Factory to all. True professionals that are driven by passion and pride.
