CRAFTING CONFIDENCE

At the heart of the design is a manifestation of the letter C. Not only a reference to our name - the trusted and renowned diamond house established in 1840. It is also a reference to quality. The 4 C's, a standard in the diamond industry indicating the quality of diamonds, and the 5th C, which stands for Confidence. The C is incorporated in the design so that the opposite ends act as a base, creating a perfect stage for the center Royal 201 stone to shine.

A wonderful starting point to maximize the effect of our perfectly cut diamonds, always supporting the emotional impact of the Royal 201 itself.
