All that you need to know about lab-grown diamonds Vs mined diamonds

There has been a lot of debate in the jewellery fraternity regarding what a lab-grown (also known as lab-created) diamond is and if it’s a “real” diamond.

Many blogs and articles have been written on the difference between a factory manufactured, lab-grown diamond versus a naturally mined diamond. So let me dive straight in as to what sets these stones apart (or doesn’t) from naturally-mined diamonds.

A lab-grown diamond shares the same physical and chemical properties as a natural diamond and is a real diamond that will last forever. They have the same sparkle you would see in a natural diamond, and with the naked eye, you will not see the difference. Even a trained gemologist would need specialised equipment to see the difference.

Lab-created diamonds are growing in popularity are here for the long haul and can no longer be treated as a fad. The diamond producer association has noted the increase in popularity of manufactured diamonds and is concerned even though they expect sales in 2022 to only account for 7.5% of all diamond sales. 

Even with the growth in Lab-created diamonds, you would find it hard to find jewellery made from them in your local jewellery store. It would almost certainly damage their inventory of natural diamond jewellery, and that currently is not a road they can afford to go down. 

Why would you choose a Lab-Grown diamond?

In the early days of sales, clients looking for traceable stones from sustainable sources would choose a lab-grown stone as it ticked the right boxes. But, of course, that is not entirely fair on the mined diamonds, as The Canadian Marked Diamonds come with a certificate telling you the mine the diamond came from and the original rough stone.

Today the biggest driver of Lab-Grown sales is the price, as they are generally 30 to 40% less expensive and honestly, you can’t tell the difference.

Will they increase in value like a mined diamond?

My honest evaluation of things is no; they will not increase in value, but neither should they fall. But ask yourself, if you buy a diamond engagement ring are you buying it to sell for a profit in later years, or are you buying it to propose to the love of your life hoping they will wear it for the rest of their lives?

Even if you were buying a natural diamond to invest in, you would not purchase it in a piece of jewellery and would look to buy it in rough form and have it cut into many stones.

Millennials are More Conscious

The most recent survey in the US found 70% of 1,000 consumers in the 21 to 40 age bracket across all income ranges said they would consider a lab-grown diamond for the centre stone in an engagement ring, an increase of 13 percentage points in only one year when 57% said the same.

Luxury Brands

Interestingly De Beers in the US have a range of lab-grown diamonds but have no plans to introduce it in the UK.

Here are some of the facts to help you decide what’s best for you!

Whichever diamond you decide is right for you will not affect the quality of your bespoke jewellery piece.

The sustainability of the stone is not an issue to consider, as you can have equal confidence in either form factor of the diamond.

If I was to show you a Lab-Grown or mined diamond with the same 4C’s you would not see the difference.

So finally, that leaves the price. And here, you would see the difference, allowing you to save a lot of money or the ability to upgrade the diamond.

So my advice is to seek out an experienced bespoke and independent jeweller who can show you both a Lab-Grown and natural mine diamond to allow you to make the right choice for you
