Beautiful and rare, diamonds are desired for their sparkle and exquisiteness. When you buy a diamond there are four points that you should always consider, collectively better known as the Four C's. Similarly, at ORRO our stones are scientifically grown using state-of-the-art and proprietary science before being hand cut & hand polished in line with stringent global grading benchmarks used in the genuine diamond industry. Each and every facet follows a mathematical formula and is placed at precise angles in relation to each other - the result is what many consider the world’s best diamond simulants. After all, every one of our very own master stone cutters has over fifteen years of experience cutting and faceting naturally mined diamonds.

The world's most desirable diamonds are colorless. The best color is D, which is almost clear white. The color scale descents from down through the alphabetical order all the way to Z – moving further away from colorless towards yellow or brown tints.
Diamonds have small imperfections embedded within them known as inclusions. The fewer the inclusions, the more valuable the stone is.
This is the size of the stone. The word carat comes from the carob seeds that were used to balance scales during ancient times.
