Guaranteed for life

Ada's created diamonds are the hardest substance on earth — ten times harder than a Sapphire or Ruby. A 10 out of 10 on the Mohs hardness scale, Ada diamonds are extraordinarily resistant to heat, chemicals, and scratching. Furthermore, lab grown diamonds are less likely to chip than mined diamonds since they have less strain, defects, and impurities in their crystal structure.

Because of their quality, we guarantee that diamonds purchased from Ada will not fade, cloud, change color, or lose their brilliance in your lifetime.  If, at any time, you have any problems with your Ada diamonds, the Concierge team will be ready to assist you. If there is a problem, we will gladly exchange your diamond for a comparable size and quality diamond.
