Pear Shape Diamond Ring Education - A Buyer's Guide

 A pear shape diamond ring is a type of diamond ring that features a pear-shaped diamond as its centerpiece. The pear shape is a unique diamond cut that is a combination of a round and a marquise cut, resulting in a teardrop shape with one pointed end and one rounded end.

PLodewyk van Bercken (also known in French as Louis de Berquem) a mid- to late-15th century Flemish jeweler and diamond cutter first designed the pear shape cut. Since then the gem has gained popularity and is the center piece in several prominent engagement rings as well as center pieces for diamond studded necklaces.

The pear shape diamond is considered a modified brilliant cut because it has a similar faceting pattern to the round brilliant cut, with triangular and kite-shaped facets. This cut usually consists of 56 facets although this may vary depending on the individual faceting pattern of each gem. Due to their elongated outlines, pear cuts tend to look larger for their carat weight compared to a round or princess cut diamond allowing more bang for the buck.

The length-to-width ratio of a pear shape diamond can vary, with most ideal cuts falling between 1.45 and 1.75. Below is a chart to use as a guide when purchasing your pear shape diamond. *Please use this table as a reference guide only
