The girdle is the widest part of a diamond. It is from where the gemstone’s top part, the crown, meets the bottom part, the pavilion. The diamond’s girdle can be as it is when mined, be polished, or even faceted. Below is an overview of the 3 diamond girdle types and the effect they have on the appearance of the stone.
Some years ago, most diamonds that were brilliant cut featured girdles that remained unpolished or natural. This gave the diamond’s widest part a frosty look after the gem was rounded using a new rough diamond. When it is viewed using a loupe, the girdle’s appearance will be white, frosty, rough, as well as opaque. Rough diamond girdle is also called a bearded one, as it appears much like the beard.
Such types of diamond girdle suggest that the thin perimeter of the gemstone is polished by diamond cutters into a facet that is clear. Polished girdle allows you to see through the gem. The whole surface area of the diamond’s girdle is polished and clean, with no facets or roughness, but a smooth strip making its way fully around the diamond’s perimeter.
Faceted girdle is the most common finishing, which one would get to see on a diamond with modern design. Much like the diamond’s rest surface area, this girdle type is one that is cut as well as polished with vertical facets. During the creation of the girdle, tiny facets get cut as well as polished around the gemstone’s outside edge removing the small feathers formed during girdling process. This type of diamond girdle is virtually unnoticeable, since it reflects the light and causes it to bend with the gem’s rest of the surface.
How Far is Girdle Important to Shoppers
When it comes to buying a loose diamond, the type of finish on the widest part of the gem will not have a significant influence on its value. It is up to the personal preference regarding which type of diamond girdle to choose. What’s more, shoppers should note its thinness or thickness, both of which affect the diamond’s symmetry as well as proportions, than the girdle type of a well-cut gem.
To find a diamond with an expert cut or one that is perfectly proportioned, look for a rating of the girdle that falls between Thin and Thick, or somewhere close to Medium.
