Master Stones
(CZ Master Color Set)

The color of a diamond significantly impacts its worth, with brighter, whiter diamonds generally commanding higher value. The color of diamonds is assessed using diamond master stones for comparison. However, natural diamond master stones are very expensive, which is why we've introduced this Cubic Zirconia (CZ) master color set. These master stones are carefully crafted to mimic natural diamond master stones with a high degree of accuracy, making them an ideal alternative for color comparison.
