You See the Light
What do you see when you look at a diamond? You see light... reflected and refracted light. The more light you see reflected from a diamond’s facets, the more fire or brilliance the diamond displays (compare diamonds using our ISEE2 system). Brilliance is beauty, and no other diamond reflects more light than a HeartStar. The HeartStar diamond is one of the finest cut and proportioned round brilliant diamond produced in the world today. It reflects up to 93% of incoming light. Average diamonds don’t even come close.

The Einstein of Diamonds
How? Way back in 1919, Marcel Tolkowsky, the Einstein of the diamond industry, published his ground breaking work on the perfect diamond. He christened it the “Modern American Brilliant Cut”. Though the cutting debate continues to this day and there are countless variants, Tolkowsky’s basic 57 facet formula has never been improved upon. (See the HearStar Diamond's legendary cutting geometry at left.)

The Most Stringent Grading and Certification in the Industry
Every HeartStar diamond is hand selected from the finest production, then regraded and often repolished. Once our cutters deem it perfect, it is then certified by the AGS. We then grade every HeartStar with our exclusive ISEE2 Grading Technology. Many of our HeartStar diamonds are then laser inscribed on the girdle with Springer's Jewelers hallmark and the AGS certificate number (optional) for your security. HeartStar diamonds are available from 1/3 of a carat to 5 carats with the best availability and value from 1/2 to 2 1/2 carat.
