Celebrating inner & outer diamond beauty

Madestones are diamonds created in a laboratory. Timeless white
diamonds and diamonds of beautiful striking color. An affordable,
conscientious and modern choice.

A laboratory grown diamond is a diamond. There is no difference between a diamond occurring naturally and a laboratory grown diamond except ‘origin’.
The most respected diamond grading laboratories the Gemological Institute of America, HRD and the International Gemological Institute provide diamond grading reports certifying that laboratory grown diamonds are exactly the same as natural occurring diamond except that one is created by science.
