Our Story

A Commitment To “Eternity” 

When you involve yourself in the world market for precious gems, and for diamonds in particular, you only have one choice.  That choice is a commitment to excellence, with no compromises.” Brett Bolton, Managing Director of Australian Chocolate Diamonds (ACD), embraces this as more than just a slogan: it is a watchword, a credo if you will. Given the success of this company and the standards ACD have set, it is also evidentiary, and very much a part of the reason they have chosen to hallmark their diamonds with the indelible name, “Eternity.”

 For over 50 years Eternity Diamonds has garnered a reputation for mining, cutting, cultivating and perfecting quality diamonds, gems and pearls inside the Australasian Quadrant of world markets. The core focus of ACD Managing Director, Brett Bolton, is to provide these markets with the most professional, efficient and ethical supply of its wide range of products. During this time the company has seen many changes in the Australian and international diamond market. Today people expect more from their jewellery than just great design, they are looking for presentations that are both unique and intrinsically exceptional—ones that engender a kind of emotional alchemy that only the finest of stones can inspire.

These are a few of the many reasons why Australian Chocolate Diamonds by Eternity was created. Australian Chocolate Diamonds have been both sourced and selected from Argyle Mines Western Australia. As the world’s largest supplier of natural coloured diamonds, the Argyle Mines are renowned for producing elegant champagne and signature pink diamonds. 

 It is usually understood only by industry experts that the transformation from a rough diamond to a finished product differs greatly. This difference is particularly true when one compares the process to perfect a chocolate diamond compared to that of a white diamond. 

There are two basic reasons for this. The first reason is that a chocolate diamond is much harder than a white diamond and therefore the cutting process is much slower. For instance, generally a white diamond takes around six hours of processing to go from a rough diamond to finished gem.  However, in the chocolate series, one laborious stone has taken us over 150 hours of cutting to finish. This stone was a 2ct C6. The second reason is that when cutting a white diamond we are cutting to reduce the colour of the light returned out of the diamond.  When people are looking for a white diamond they want it as white as possible of course.

However when cutting coloured diamonds we work to enhance the natural beauty from within the stone. In the past, this was done in a way that directly affected the brilliance and sparkle of the gemstone. Eternity Diamonds have found a way not only to capture the colour, but also to ensure that the brilliance and sparkle of the stone is maximised and even embellished. So much so, that now, even when you compare them to white diamonds of the same quality the scintillation will often be the same or greater.

 At this stage of its dynamic growth and development, ACD retains a team of 70 dedicated cutters applying all of their skills and craftsmanship to ensure that every stone is precision cut, capturing and bringing to life the true brilliance of your Australian diamond. Australian Chocolate Diamonds are sure to be a stunning statement amongst an array of pieces. With the confidence of independent grading and absolute integrity that goes into every piece, you will be assured in the knowledge that your diamond has been certified and laser inscribed for added security. My Diamond Story allows your Australian Chocolate Diamond to provide its own genealogy and chain of origin by recording each step of its journey to you.

This even includes the lot number given to the parcel from which it was originally sorted by the Argyle office. These lot numbers give us a guide to the colour, size and also quality of the parcel. This certificate includes the rough weight, the stone’s original weight from the mine before any cutting took place.  It also gives you the colour (graded from C1 to C7, where C1 is the lightest through to a deep chocolate colour of C7) as well as the clarity, which follows the GIA grading system of flawless through to I-3 for heavily included diamonds. The Australian Chocolate Diamonds generally range from VVS1 through to I-1.

About The Owners

A Family Tradition

[Very often, what connoisseurs know that the general public does not is that the difference in a diamond often has to do with the House that creates it. Australian Chocolate Diamonds Managing Director Brett Bolton recounts the Bolton family history and the sense of purpose that helped them evolve into what ACD has become today.] 

At ACD, we take our commitment to our Diamonds seriously. And the reason is as simple as it is precise: It is more than just a business. It is a family tradition, one that began over half a century ago. Bolton Pty Ltd was founded in 1962 by my grandparents Patricia and Dennis Bolton. Starting life as a coloured gemstone business, the Boltons (along with Patricia’s son Kym) quickly discovered that, with a few small enhancements to the cutting process, an average looking Gemstone could—in the hands of a master cutter—become one of ‘gem quality’. This was accomplished by means of a process whereby, looking at the colour variations within the stone and maximising the angles, the cutter could not only reveal the best possible colour, but also allow light into the stone that would reveal brilliant flashes of hue and value so characteristic of quality gemstones. 

This ancient yet modern technique was so successful that the company quickly became known as the leader in the fine coloured gem industry inside the Australasian sector of global markets. During the period of the late 1990s, most gemstones were being re-cut and shipped from Asia due to an opportunity that arose to setup a Ceylon Sapphire cutting facility in Sri Lanka. Originally, this gave our family an understanding of the rough Gouder and, more importantly, the means by which the rough stones were cut. Specifically, when cutting coloured stones from the rough, one cannot simplistically cut each stone via the same method. If, in fact, you were trying to showcase the individual gem’s ultimate colour and brilliance, you would finally have to individuate the stone…so that, in its way, each stone becomes its own work of art with its own identity. 

At this stage we were also purchasing the Champagne and Cognac series diamonds from Argyle and other sources around the world. Even then, however, most of the diamonds still needed to be recut in order to maximise their colour. The cutting quality of these diamonds was, by today’s standards, quite poor. This was due to the hardness of the diamond rough, as well as the lack of time given to cutting and polishing these goods. From 2000 to 2011, we purchased many diamonds but soon found that virtually every stone needed recutting in order to improve the make of the diamond. We also tried many cutting techniques to enhance the colour and brilliance of the coloured diamonds, but it was very much hit and miss. One diamond would look dazzling, and the next cloudy and dull, even when cutting to GIA triple EX (high international standards).

After travelling the globe following different supply chains, we discovered what we were looking for was actually at our back door—the Argyle rough, sourced from the then little known Kimberly Mines in Western Australia. After we had purchased a few small 40-carat parcels on the open market we realised that, in order to gain access to the parcels (at least in the quantities we required), we absolutely needed to get closer to the source.

In early 2013 Kim Truter, Managing Director of Argyle Australia, introduced ACD to the world of rough-diamond trading. Through his contacts we were invited to the offices of Rio Tinto in Antwerp to meet the team and work together to advance my personal vision of what we were trying to achieve. Once we had secured the rough, it was time to move our attention onto the cutting process. 

Starting with only 20 cutters, we at ACD quickly came to realise it was just not enough. Not only could we not cleave or laser cut the rough, we soon discovered that the cutting and polishing process was much slower than we had first anticipated. The first 20 diamonds took 3 months and the results were underwhelming. The diamonds were very well cut—all Hearts and Arrows and graded triple EX by GIA standards—but there was still so much more within the stone that needed to be brought out.

 After much refinement and soul-searching, we realised we had been looking at the rough from the wrong angle. It was not about cutting to triple EX standards, nor was it about achieving hearts and arrows. It is about cutting for colour and capturing the fire within the stone- going back to our roots of looking at Gouder, and cutting a gem quality stone was the answer. By looking at a computerised model of the rough and subsequently cutting the rough to achieve maximum weight, we had found a way to bring out the golden brilliance of the diamond. The results were spectacular to say the least. Every diamond shone forth, not only with the depth of colour we were looking for, but also with that inner fire that had been missing until this point. With the first stone off the polishing wheels, we knew that the paradigm for Australian Chocolate Diamonds had finally been established.

Today we have not changed our philosophy and have, in fact, expanded it. Every one of our now 70 cutters are master diamond cutters, studying and ‘getting to know’ the rough before they even touch the cutting wheel. All Australian Chocolate Diamonds are checked at each stage of the cutting process by our head Diamond Cutter, to ensure every stone is going to meet the strict standards we have put in place. This guarantee ensures every diamond is precision cut, capturing and bringing to life the true brilliance of your Australian Chocolate Diamond.
