Did the remarkable age of diamond come before or after the age of dinosaurs? This might be one of those legendary conversations which ranks up there with the chicken or the egg debate. Perhaps we should simply agree that we may never know when the age of diamonds first began. Because some people promote the idea that diamonds are billions of years old, while others say millions. The De Beers Diamond Trading Company suggests that Diamonds Are Forever. With that in mind, the only logical conclusion is that the age of diamonds was forever ago.
De Beers began promoting “a diamond is forever” back in the 1940’s. It goes without saying that those were simpler times from a technological perspective. Very little was known about the origin of diamonds, let alone the age of diamond. The latter of which was estimated based upon where diamonds were found.
If diamonds are discovered deeper in the ground than dinosaur bones, then logic dictates that diamonds are older. At the same time, the technology exists today to create synthetic diamonds quickly and easily. This is something that a division of General Electric began working on back in the day. You know, when dinosaurs were still roaming the earth and guys like Brian Gavin were cutting their teeth on diamonds.
This last bit is not speculation by the way. How do I know such things? Because Brian Gavin is one of my original mentors in the diamond business. We were buying A Cut Above® hearts and arrows diamonds from Brian back in 1998. Which makes me… Awww shoot! That’s right, as old as a dinosaur! But one of the younger ones! Brian Gavin is a 5th generation diamond cutter, which clearly makes him older.
With this in mind, you might assume that us old guys have some insight on the age of diamonds. Alas, we don’t possess such amazing knowledge, because diamonds are older than dinosaurs. How do we know? Because De Beers says so…
Once upon a time, in the Age of Diamonds, there was a beautiful princess. LOL, you know we’re not really going to go there, right? And yet, up until recently that is how a lot of diamond lore appears to have been written. After all, companies like De Beers spend a lot of money searching for diamond deposits. They don’t spend that much trying to discover the exact age of diamonds. What’s the point, really?
With that in mind, does it matter whether the Brian Gavin Signature diamond in your ring is 900 million years old? Will you appreciate it even more if it is 3.2 billion years old? Or by chance, will anywhere in between suffice? Because I’m willing to bet that all you really care about is the incredible light performance and sparkle factor. Which is probably the #1 reason to buy a Brian Gavin Signature diamond to begin with.
Look at the optical precision of this 1.081 carat, G-color, VS-2 clarity, Black by Brian Gavin diamond. It takes tremendous skill to align the facets so perfectly that this hearts pattern emerges. It’s not the age of diamond that matters, but rather the skill with how the cutter unleashes its inner beauty. But while it’s Brian Gavin’s job to do that, it’s De Beers job to find more diamonds. Which is an endeavor that is bring attention to the age of diamonds, in a new and surprising way.
Researchers are using radioisotope analysis to determine the age of inclusions within diamonds from the Venetia mine in South Africa. The research indicates that some diamonds might not be as old as people think they are. From an industry perspective, this means that there might be additional diamond deposits to discover.
De Beers donated 26 diamonds to the experiment conducted by researchers at the Vrije Universiteit (VU) Amsterdam. Nine of the 26 diamonds are about 3 billion years old. While 10 of the diamonds are a little more than one billion years old. The time period coincides with a major volcanic event in Zombabwe, approximately 1.1 billion years ago.((Diamonds show Earth still capable of ‘superhot’ surprises, Science Daily, September 21, 2017))
By assessing these flaws, researchers are able to determine the age of diamond crystals. Minerals trapped within the carbon crystal structure provide clues about the conditions and rocks in which they formed.((Diamonds show Earth still capable of ‘superhot’ surprises, EuroPlanet, September 21, 2017))
Speaking of which, how cool is the garnet mineral inclusion within this piece of diamond rough? This is a photograph by Michael Gress, showing one of the diamonds from the Venetia mine. Pretty cool stuff, which I always get a kick out of seeing. Imagine how much skill it takes to transform a piece of diamond rough, into the star on your finger.
“Conventional thinking has been that the level of melting needed to create these diamonds could only happen early in the history of the Earth when it was much hotter. We show that this is not the case and that some harzburgitic diamonds are much younger than assumed. We propose that our younger set of diamonds formed in a special environment where a major plume from the deep mantle was raised towards the surface and underwent extensive melting as the pressure reduced,” said Janne Koornneef, who led the study, published today in Nature Communications.((Archaean and Proterozoic diamond growth from contrasting styles of large-scale magmatism, Nature Communications, September 21, 2017))
At the present time, mining companies like De Beers focus on the oldest kimberlite pipes. This is because they assume that“harzburgitic” diamond crystals can only be found in very old mantle. Which is not to say that all diamonds are from harzburgite. But rather that diamond hunters look for this rock as an indicator that the area might contain diamonds. This might lead diamond prospectors to explore deposits which contain younger diamonds.
Before you call Brian Gavin to determine the age of your diamond, I have some sad news for you. There is a reason why De Beers donated 26 diamonds to the study, instead of loaning them to the researchers. That is because the process of dating diamonds requires breaking them. That is the only way extract their impurities for the sake of analysis.
This means that there is no way for anybody to tell you the age of your diamond with any accuracy. Suffice to say, it’s probably between 900 million and 3.2 billion years old. However, this new research might enable companies to create niche markets for diamonds from certain mines. With that in mind, I’m going to suggest a new collection of Brian Gavin Diamonds.
Wait for it. Wait for it.
Pause for Dramatic Effect.
After all, in an email sent to Rapaport News, Trevor Nace, geologist and founder of Science Trends wrote: “There could be a market for something like ‘this quarry primarily has 3-billion-year-old diamonds,’ or something like that. [It] probably could be marketed as a niche on the quarry or region, but not by the diamond specifically.”((Miners Could Start Hunting for Young Diamonds, Rapaport News, September 26, 2017))
While all of this is very interesting, you might be wondering about the real benefits to you as a consumer. The most obvious benefit that I comes to mind, is the potential for more diamonds to be found. The demand for natural diamonds is higher than ever, with more and more people getting engaged every day. Which means that diamond cutters like Brian Gavin will have more material to work with.
Which will make it easier for you to find the perfect Brian Gavin Signature diamond for your engagement ring. Although this may be true, the reality is that hearts and arrows diamonds are still quite rare. There are very few diamond cutters in the world who are capable of producing them. It takes a great deal of skill and talent to achieve the higher degree of optical precision. At the same time, the volume of light return and sparkle factor are worth the wait!
Which is why I write about Brian Gavin Signature diamonds so often. Brian used to produce diamonds for our private label collection. With that in mind, I know exactly what to expect in terms of light performance. Which is why I recommend the diamonds from the BGD Collections so highly.
