Asscher Cut

First produced by the Asscher Brothers of Holland in 1902, the Asscher Cut Diamond regained popularity in 2002 after its one hundredth anniversary and a slight modification to the cut technique. The Asscher Cut’s deep pavilion and precision creates an enamouring appeal. While like the Emerald Cut, the Asscher tends to offer a bit more sparkle, due to its high crown and 58 facets.

Brilliance is achieved through light reflection among the square facets seen underneath the table. The Asscher Cut’s trimmed corners give it extra style and stability.

Heart Shape

A prominent symbol of love, the Heart Shaped Diamond boasts an exquisite figure that can be set in a ring, pendant or other jewellery piece. Heart Shaped diamonds range in slenderness and width, selected primarily on personal preference. A well-cut Heart Shaped Diamond should be symmetrical, so it appears balanced and full. The point or cleft of the diamond should be distinct. In addition to being a sign of romance, the Heart Shaped Diamond requires a premium cut, prolonging and possibly increasing its value over time.

Length to width ratio: An ideal length to width ratio is 1.00. The lower the ratio, the more “chubby” the Heart will look. If the ratio is above 1.10, the Heart will appear more stretched (elongated, tall and thin).
