Yes, they are real diamonds.

Quite simply, a lab grown diamond is a diamond: carbon atoms arranged in a diamond cubic crystal structure. The only difference between mined diamonds and lab grown diamonds is the origin of the diamond. Lab Grown diamonds and mined diamonds have the exact same physical properties.

Lab grown diamonds are indistinguishable from their natural counterparts; side by side they are identical.

A cubic zirconia is not a diamond. It is merely a diamond simulant, meaning that it looks similar but not exactly like a diamond. In fact, a Cubic Zirconia contains zero carbon, whereas diamonds (mined and grown) are made entirely from carbon.
Put another way, Cubic Zirconia is a cheap imposter to a diamond that is a different material entirely, whereas a synthetic diamond is chemically and optically identical to a mined diamond.

At idem Diamonds we work to ensure you get the greatest value.   The reality is the foreign exchange, gold price and diamond price change every day.   Many retailers keep the price fixed by factoring in the work of these factors to ensure that make their profits.  

Our approach is to change the prices daily to ensure you are always charged the right price!!

Open and transparent costs, that is a change!

Because the diamonds have the same composition down to the atom level they will test the same.  They are chemically and optically the same, they are idem Diamonds.

There are only certain locations in the world that naturally formed diamonds came up from the magma to the surface and can be mined.   Many of these are in countries with poor environmental standards so often there are generations left to suffer from mining.
