How do I calculate the price of a diamond?

Our diamond price calculator provides you with the final price for a diamond but you can easily calculate the price per carat by dividing that final price by the carat weight of your diamond. Diamonds are priced in terms of price per carat because it is easier for diamond dealers to discuss pricing in these terms.

Are lab-grown diamonds cheaper than natural diamonds?

Most of you probably know that lab-grown diamonds have a lower price than natural mined diamonds. Taking a quick look at some of the best online diamond stores will prove our point. The experts usually say lab diamonds are generally 20-40% cheaper than a mined diamond of the same grades. However, lab diamond prices fluctuate.

How much do lab diamonds cost?

The higher the cut, colour, clarity and carat of a diamond, the more expensive it will be. So how much do lab diamonds cost on average? With the grades we typically advise (Excellent cut, F colour and VS2 clarity), you’d be looking at around £1,800 for a 1 carat lab diamond. You may even find top quality lab diamonds at a lower price than this.

How long do lab-grown diamonds hold their value?

However, if you determine value in a non-financial sense, such as the hardness, quality and beauty of the diamond, then lab-grown diamonds will hold their value indefinitely. As they are chemically identical to natural diamonds, lab diamonds are forever, as the saying goes.
