Diamond Girdle

A Girdle is a narrow rim around the widest fringe of the diamond. it is also sometimes mentioned because the “setting edge” where a diamond is held when set in jewelry. The Girdle must be good – it cannot be too thin or too thick or it’ll affect the strength of the diamond. If a Girdle is just too thick, it can affect the stone’s brilliance and it’d also make it heavier (which, in turn, makes it more expensive). this is often an excellent example of how knowing these diamond terms can assist you to get a better value diamond at an honest price.

When a diamond is sent for Certification, it is measured at various points along the Girdle to determine its thickest and thinnest points.

The Girdle is most often rated as a range, like ‘Very Thin to Thick’, to accommodate the variance between the thickest and thinnest point.

Girdle ratings and their characteristics can fall into one or more of the following categories:

girdle

Extremely Thin: could also be susceptible to chipping or breaking; care should be taken when setting stone;

Very Thin: excellent gemstone proportion but care should be taken when setting stone;

Thin, Medium: Ideal gemstone proportion;

Slightly Thick, Thick: Excellent to Ideal gemstone proportion;

Very Thick: Good gemstone proportion

Extremely Thick: May make a diamond look smaller since more depth is obsessed by Girdle.

Why does a Diamond Cutter Cut a Thick Girdle?

The Girdle is the widest part of the diamond, which equals weight, which, in turn, equals a higher justified price. This practice has been going on in the diamond industry for a long time.

The price contras between a 0.90 carat and a 1.00 carat are approximately $1,500 to $2,000. This is often a significant financial incentive for jewelers and cutters. Over 50% of the diamonds on the market today have thick Girdles. This is often a part of that you just won’t find many other jewelers talking about.
