Frequently Asked Questions

Black opals are known to be the rarest opal variety because there are less of them. They are also said to be the most valuable because the color is the most vivid. The black opal shines with color similar to any other opal, which is why it is said to be the rarest variety.

Some black opals are prized as highly as diamonds because of their rarity. Black opal is the most valuable of the opals.

According to jewellery sources, the most valuable black opals come from opal fields in and near Coober Pedy and Kurrawa Queensland, and the most popular black opal gemstone is the 'black opal doublet' which consists of an opal backing and an opal top.

It is either a man-made doublet made of colorless opal (commonly White Opal) with an opal top such as Trachyte, or a natural stone where the backing is a Black Opal and the top is a White Opal.

Black opals are characterized by flashes of bright, deep reds and oranges caused by the different types and layers of silica that reflect and absorb

Black Opal is the rarest and most valuable opal on earth.

Black opal is rare because of its full spectrum of color. The ability to produce its deep, uniform black body with all hues, is what makes it the rarest type of opal.Black opal is rare because of its full spectrum of color.

Black opal is the rarest opal on earth. It is extremely rare because it is not found in the traditional mining areas of Australia, but rather in remote and very hard to access locations in the country's north.

The opal is a beautiful gemstone, but only a handful of places on the planet have been known to produce it. Lightning Ridge, Australia, is one of those rare places. In fact, this small town on the continent's east coast produces more opals than anywhere else in the world. In fact, only about 1,000 people live there, which is about double the population of Vatican City.

Black opals are so hard to find. The gems are formed when a solution of silicone dioxide and water evaporates from the cracks of sandstone. The darker the body tone, or the more opaque it is, the more desirable it is. This composition means that black opals are more delicate than diamonds.

It can cost over $10,000 per carat, making it one of the most expensive gemstones in the world. What makes black opal so expensive? Black opal is one of the most enchanting gems in the world, sought after for its seemingly infinite color spectrum. However, mining black opal is incredibly difficult. 

In Australia, Lightning Ridge is famous for black opal, the darkest and most valuable form of opal. The White Cliffs are known for white opal. The mining fields are synonymous with the world's most famous gem quality black opals from Lightning Ridge

Opal is one of the most fascinating gemstones in the world. It dates back centuries, and it's origins are lost in time. It was named "opalos" in Rome, and eventually became known as "black opal." The name "black opal" describes its dark body tone, and it's easy to see why! Opal is a unique gemstone that can't be matched. It symbolizes creative stimulation and ingenuity, and no two opals are the same.

AUD$1 million. 180 carats. Measures 3 by 1.8 inches. The rarest of all opals, a black opal from 1938 is the most valuable in the world. It was found six meters below the seabed, and it features an unmistakable impression of a starfish on the back.

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.

I had a great experience working with Mike and Opal Diamond Factory in creating my fiancé’s opal and diamond engagement ring. The whole process was enjoyable and seamless. First of all, together we found the exact opal I was after and then designed the ring around it. I couldn’t be more happier with the final outcome and cannot recommend Mike and his staff more highly. Thank you for creating something so special for both of us. We will be back to create our wedding bands.

My experience here was nothing short of perfection. When I first came in looking for an engagement ring, I wasn't sure what I wanted other than a few minor details like the colour of the metal and type of opal. This is where Mike's knowledge and skill really helped me. While he was showing me the different styles and shapes of the rings, he was very polite and respectful with what I was trying to achieve. But I was still completely lost on the shape of the ring, as nothing really stood out. That was, until Mike pulled out his phone and showed me a concept he had designed, and I was completely convinced that it was the one. It took a few weeks for the ring to be completed, and I would be lying if I said I wasn't worried that I had made a horrible mistake by building an engagement ring without seeing an example or anything even similar before. But all my doubts went away when I laid eyes on the finished product. Thank you Mike and the ODF team, everyone who has seen it has fallen in love with it, especially my now fiance.

Great communication, listened and was exceptionally helpful. Not pushy in the slightest. Made the process a breeze and was always happy to communicate. Didn't feel silly when asking questions. Would thoroughly recommend and use again.

I recently purchased the beautiful 'initial' necklace in gold, it is gorgeous, so dainty and sparkly. I couldn't recommend Mike and the wonderful team at ODF enough. The necklace arrived wrapped with care and it is perfect! A lovely family business that cares for their customers which is important to me. Thank you Mike.

Couldn't recommend Opal Diamond Factory enough. Mike was extremely helpful in assisting with the design for the perfect custom engagement ring for my fiance. This was all made so easy even though we are in completely different states - all without needing a single phone call. It didn't even matter that I had a million questions, Mike was very accommodating and went above and beyond to answer all my queries and requests. It was honestly an enjoyable experience. The selection of opals they have is absolutely beautiful. Thanks again for the amazing service and outstanding ring!!

Mike helped my husband pick out my beautiful engagement ring diamond and design my ring style, whilst delivering on fantastic service and helpful advice. We also went back to Mike for my matching wedding band and my husbands wedding band too. Super friendly service and great after sales support on our rings. Would 100% recommend Mike and the ODF team!
