the idem difference

Real Diamonds

We have chosen the name IDEM from its Latin meaning “same”. The only difference between a lab grown diamond and a natural diamond is its origin. Lab grown diamonds are indistinguishable from their natural counterparts; side by side they are identical. Lab grown diamonds are graded using the same 4 Cs, only our product provides a much more sustainable and affordable option.

Great Value

Lab grown diamonds offer incredible value and are more affordable than mined diamonds of comparable size and quality.

Lab grown diamonds sell for up to 70% less than mined diamonds, owing to the lower expenses of the mining process, a shorter supply chain, and a more competitive market.
