Most of the unique marquise diamond rings have more than 50 facets; 2:1 is its ideal length-to-width ratio, though there is an array of proportions available. Although marquise cuts tend to be shallower, these gemstones still show exceptional brilliance and fire. Certain marquise diamonds are cut with French tips, which replace the bezel at pointed ends with a modified girdle and star facets. This girdle thickness improves the diamond’s durability, as it protects the corners of the gemstone from chipping. The most important factor to consider when choosing a marquise diamond ring is its cut. It should be cut in perfect symmetry and should have sharp points, and wings that are not excessively bulged or flat. Its length-to-width ratio is more or less a personal choice. Another important factor to note while buying the marquise diamond is the thickness of girdle. Thicker the girdle, the durable will be the gemstone. Yet again, the thickness of girdle or the intersection of the marquise diamond’s top and bottom facets, which outlines the circumference, should also be considered. An excessively thick girdle contributes to the weight of the diamond and can affect the sparkling effect, whereas a thinner girdle may enhance the risk of chipping. So, the sufficient girdle thickness ensures safety and light performance of the diamond ring.
