These proportions give Old European Cut diamonds their charm. Old European Cut diamonds typically feature steep crown angles, smaller table facets, polished culets, lower percentage “lower girdle facets” and broader facets compared to modern rounds.
TheĬanera European Round is an Old European Cut diamond which is produced in the modern day to improve some of the deficiencies of antique OEC diamonds. OECs specifically and vintage cut diamonds in general are experiencing a huge revival and a surge in popularity in the modern day. The Old European Cut (OEC) Diamond was the precursor to the modern Round Brilliant Cut diamond and was produced from the 18th century onward. The popularity of the Round comes at a cost, it usually fetches a price premium of 10%-40% more than other shaped diamonds. The RBC will typically have a greater diameter compared to other shapes having the same shape owing to its relatively shallow ideal depth and its symmetric shape. A steep crown angle is complemented by a shallower pavilion angle, and vice versa. The relationship between the crown angles (above the girdle) and the pavilion angles (below the girdle) is complementary. Round Brilliant diamonds are typically cut to have a total of 57 facets 33 on facets on the crown and 24 facets on the pavilion. For the Round Brilliant diamond, “Ideal Cut” will guarantee immaculate proportions, brilliance and fire. The cut consists of strategically placed facets intended to maximize the diamond's brilliance and its overall appeal. The Round Brilliant Cut or RBC accounts for more than 75% of diamonds sold worldwide, it is by far the most popular and most sought after diamond shape available as it is the most 'brilliant' of all cuts.
