So are these lab generated diamonds more costly to produce?

Are lab grown diamonds less expensive than natural diamonds?

The long process and the manpower that it takes to mine diamonds is generally the reason for their high price, along with their quality and size of course.

Lab technology can now offer a much more cost-effective way of producing a beautiful sparkling quality diamond.

On average lab-grown diamonds can be between 30-50% cheaper than mined ones.

Jewellery giants such as Pandora are moving over to 100% lab grown diamonds in their collections.

Their spokesmen say that given lab diamonds are cheaper, they are hoping their sales will increase.

Pandora's chief executive, Alexander Lacik told the BBC in a recent report:

“We can essentially create the same outcome as nature has created, but at a very, very different price".

He goes on to say that they can be produced up to a third less than traditionally mined diamonds.

Do Lab created diamonds hold value?

There does seem to be some confusion as to whether lab-created diamonds hold their value, with many reports online and by some diamond retailers that they have little resale value.

This isn’t the case...

Regardless of whether a diamond is man-made or mined, all diamonds are priced using an internationally accepted pricing system.

This system is known as the Rapaport Pricing Method and it determines wholesale and retail pricing.

Prices are generated first based on what’s known in the jewellery industry as the ‘Four C's of diamonds. These are:

● Carat

● Cut

● Clarity

● Colour

Then, whether they are lab grown or mined is taken into consideration.

There sometimes can be a little confusion between a lab grown diamond and cubic zirconia. Let’s clear that up for you below.

Are lab grown diamonds cubic zirconia?

Cubic zirconia is not a diamond but is made from made elements to replicate the look of a real diamond.

Cubic zirconia is not a lab grown diamond.

Do lab grown diamonds last?

Diamonds are forever is certainly a memorable advertising slogan and ensures many of us understand their longevity!

One of the reasons is that it's almost impossible to damage a diamond.

As lab grown diamonds have the same chemical properties, it means they too are just as indestructible.

Lab grown diamonds rank at 10 on the Mohs scale, the same as traditionally mined diamonds. This is a scale that measures the scratch resistance of any material.

How long does it take to grow a lab grown diamond?

Traditionally mined diamonds can take not just millions but billions of years to grow! Their rarity and the length of time to create one is a couple of the reasons for their high price.

Lab grown diamonds typically take less than a month to grow.

White diamonds take the longest time to grow, taking a couple of weeks to grow a 1 carat diamond. However, a yellow or blue diamond can take as little as 5 to 10 days.

Can you tell the difference between lab grown diamonds and mined diamonds?

The chances are that you couldn’t tell which diamond is lab grown and which is mined. The reason is simply that they are both diamonds.

They share the same clarity grades and both have the same natural inclusions. So it is virtually impossible to tell the difference by eye because the only difference is their origin. the same natural inclusions.

Can diamonds be IGI certified?

Diamond specialists use a corporation called the IGI (International Gemological Institute) certification to label and classify diamonds.

An official IGI certification for diamonds shows the authenticity of a specific diamond and can’t be done simply by a jewellery or diamond specialist.

GIA has been grading laboratory-grown diamonds since 2007.

IGI Diamond Reports give an accurate assessment of a diamond's cut, colour, clarity and carat weight according to strict international standards.

And finally…

Olya Linde, who is one of the lead authors of the Bain report, agrees that there is room for both traditionally mined and lab grown diamonds.

"I believe that natural diamonds and lab grown diamonds can wonderfully coexist and grow the overall diamond market. There's a clear demand for each type of product."
