Incredibly 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!

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.

OPAL 101 - BLACK OPAL

Black opal is considered to be the most exclusive stone. Black opals naturally have a darker body tone, ranging from a dark grey semi-black appearing underbelly to a jet black tone. The naturally dark appearing under side of a stone effects the colour vibrancy present within an opal, making the stone appear brighter in colour and therefore higher in value. Along with the colour in the opal, other factors come into play when determining the overall value of a stone. The brightness and pattern in a black opal impact the stone value.

Black Opals are known for being mined in the town of Lightning Ridge, in northern New South Wales. Their distinct naturally dark body tone and often bright, vibrant colours have thought to be exclusive to Lightning Ridge but have also been discovered in Minitibie, South Australia.
