Princess cut moissanite and diamonds have intense sparkle and intricate cross facets making it a favourite which looks good in just about every setting.

The Princess cut as we know it today, can be traced back to the 1960’s. In 1971, the diamond cutter Basil Watermeyer patented a new diamond cut with the name “the Barion”. This looked already a bit like the Princess, but the many symmetrical lines of the Barion made it very difficult to cut this shape correctly. Years later, this name changed into the Princess cut.

The cut has a square or rectangular shape when viewed from above, and from the side is similar to that of an inverted pyramid with four bevelled sides.

The stones shown on the model’s hand are for reference only. Actual carat weight availability may vary.

In the event that another jeweller sets your stone, the Lifetime Stone Guarantee will be void.
