There are a few things to consider when choosing between a lab grown or natural diamond. Here I write about, what I believe to be, the most important elements in deciding between these two gemstones.
What Are Lab Grown Diamonds?
Lab grown diamonds have the same chemical and physical properties as natural diamonds- the only difference is that they are man made.
They are created in a laboratory or factory under high pressure, high temperature (HPHT) just like in nature. Or they can be created using chemical vapour deposition (CVD) using a natural gas like methane and high temperature and pressure.
Lab grown diamonds have been around since the 1950’s. These synthetic diamonds have been used in technology and industrial sectors. They have been used in scalpels, X-ray radiation detectors and can cut through steel like butter!
Synthetic diamonds have recently reached mainstream jewellery and are now becoming popular for their lower price point and eco friendly label, not to mention their abundance of supply, but there are some things to consider.
What's The Difference In Lab Grown And Natural Diamonds?
At first glance, there is no difference. They have the exact same chemical composition, but there are a few important things to note in how they are manufactured, marketed and valued.
Are Lab Grown Diamonds Rare?
Lab grown diamonds are massed produced. They are not rare like natural diamonds and never will be. This is absolutely fine, but remember they will never have the exclusivity or luxury label that a natural diamond carries.
Are Lab Grown Diamonds Cheaper?
One benefit that I can see for the customer is the cost of a lab grown diamond. You can now get a larger diamond for your budget compared to what you can get in a natural diamond. They do not however, hold their value like a natural diamond. In a Forbes article, Jean Ghika, global director of the auction house Bonham’s says “I have yet to be convinced that there is a demand for lab grown diamonds on the secondary market”. This is something the consumer might forget to take into consideration. So if you want your diamond to keep it’s value- I would recommend investing in a natural diamond.
Are Lab Grown Diamonds Sustainable?
Massive amounts of energy is needed to create one lab grown or synthetic diamond.
Looking forward, the energy source used to create these diamonds needs to be considered and the m
