David Fairclough is proud to introduce the most beautiful square diamond on the planet, the HeartStar Squared. Mathematically modeled to return optimal light performance, the HeartStar Squared will outperform all other square diamonds.

The secret to this diamonds beauty starts with the skill of the cutter. Unfortunately, most diamond cutters are proportioning their diamonds to retain carat weight. Our HeartStar Squared is engineered to produce what people see most, Sparkle! It is the only square diamond in the marketplace that exhibits the Hearts and Star pattern when examined in the HeartStar viewer.

We never thought it was possible to capture the breathtaking performance of a HeartStar round brilliant in a square diamond…until now. What is truly amazing
is the HeartStar Squared will
outperform the vast majority
of round brilliants.
