Spark Jewels are graded by independent diamond grading laboratory International Gemmological Institution (IGI).
Spark Jewels diamonds have the same exceptional hardness, stiffness, and thermal conductivity as their Earth-mined counterparts.
Lab created diamonds offer excellent value, and are scientifically more affordable than natural diamonds of comparable size and quality.
Our collection of ethical and affordable conflict-free spark diamonds are more beautiful than anything we will ever get out of the earth and come free of any negative environmental or social impact.
Our spark diamonds are 100% pure crystallized carbon and identical in every way to earth-mined diamonds.
For every carat of diamond that is mined, nearly 100 sq ft of land is disturbed and almost 6000 lbs (2.7 tonne) of mineral waste is created
