Most people have heard the great decades old marketing slogan by De Beers “Diamonds Are Forever”. Well, ironically to their displeasure, lab grown diamond’s beauty will last forever too. The reason is due to both having the same exact chemical composition, as both are made of the purest carbon. The only real difference being is that one comes to the Earth's surface and then gets torn out of the ground, inflicting massive trauma to the earth and its inhabitants along the way. The other comes cleanly from incredibly high-tech laboratories through the use of advanced material science and physics.
The colour in lab grown diamonds will stay the same forever, a claim fully backed by science. However, the hatred, and especially, fear from the mined diamond industry towards lab grown diamonds gave birth to a few fake and misleading articles making the rounds, spreading false statements such as: “lab grown diamonds change in colour” and the likes. They are simply false claims, and nothing more than malicious statements made desperately against the new emerging industry.
In fact, if we really dig into it, between Lab grown diamonds and mined diamonds, which one is best? Lab grown diamonds take the #1 spot for many practical reasons. The most obvious reasons being the price difference, eco-friendliness, being ethically sourced and conflict free. Those are the obvious reasons, but we thought why not also mention some less obvious ones which are normally not brought up or discussed?
No fluorescence, due to lab grown diamonds being made in a meticulously controlled environment they do not suffer from fluorescence. On the other hand, mined diamonds are at the mercy of nature during its formation, so it’s a coin flip whether they develop fluorescence or not. So, what is fluorescence? To put it in simple terms, fluorescence can radically affect and alter the look of a diamond by making it look milky, cloudy or foggy, or in other words, without any vitality or life. It would not be an understatement to say that fluorescence is a curse to mined diamonds.
Cutting to perfection, the advantage of making diamonds from scratch is that there is more uniform and well-defined rough diamond to start cutting in and the laboratories can tailor make shapes according to what diamond cuts need to be made. The extra rough material allows the cutting of diamonds that are perfect without having to compromise the shape and proportions. On the contrary, rough diamonds mined from the ground come in random and varied shapes and forms. This drastically limits the yield that diamond cutters can get from the rough stone, but most importantly it forces them to sacrifice the optimal ideal cut and instead cut to get the most weight (carat) from the rough diamond resulting in a less vibrant and dazzling final diamonds.
No surface reaching inclusions. It is rare to come across man made diamonds which have surface reaching inclusions, however, it is a lot more common in mined diamonds. These may be noticeable and distracting inclusions. When a diamond has a surface reaching inclusions, it can compromise the structure of the diamond, sometimes catastrophically cracking under pressure during the setting into jewellery.
In summary, lab created diamonds will keep their stunning look forever, and even though they are both made of the same material and we can safely conclude that lab grown diamonds have a lot of inherent advantages over mined diamonds that are not just limited to the significant cost savings, ethical and environmental friendliness. They have more complex and hidden benefits.
