Thin? Thick? The latter option is my favorite
One of the parameters that may be seen on a diamond's certificate or simply mentioned on a diamond website is called "Girdle," and the possible values that it could be measured at are Thin, Thick, Medium, and variants of these three.
Where does the girdle come from, and what does it indicate?
The Girdle is the level part of the diamond's circumference. This part of the diamond can be found between the crown and the pavilion. It is common practice to express the Girdle's thickness not only in absolute terms (Thin, Thick, etc.) but also as a percentage of the circumference.
Bruting is the process that results in the Girdle. Wikipedia defines brutality as "the method of shaping a diamond into a sphere by placing two rough stones on axles that spin in opposite directions and allowing them to grind against one another. It's also possible to refer to this as "girdling." ".
A lathe is a machine used to grind diamonds into a desired shape by grinding them against each other, a process known as bruting. A diamond's girdle faja colombiana can be treated in a few different ways: with facets, a smooth and sparkly surface, or no finish at all.
Faceted girdles, which can have up to a hundred small facets, are standard on modern diamonds of a certain size or greater.
Because it does not affect the diamond's beauty or quality, a bruted girdle does not degrade a diamond's grade. If the diamond is a 'fish-eye diamond,' only then will the Girdle have any effect on the stone's appearance or value.
A fish eye is an unattractive defect that shows up within the diamond's Table. An eye of a dead fish has a similar slightly distorted and lifeless appearance. The fish eye shape is a duplicate of the waistline. It looks like a big oblong inclusion if the girdle isn't polished and it's on the thick side.
If the Pavilion is shallow, the Table is large, and the Girdle is thick and not polished, then fish eyes will be more pronounced. The impact is amplified when multiple of these elements are present simultaneously.
For maximum brilliance, a diamond's girdle should be neither too thin nor too thick. You can expect the measurement to be something other than a simple "Thin" or "Thick" only seldom. Yet, descriptions like "thin to somewhat thick," "medium to extremely thick," etc. are much more typical.
There may still be traces of the original rough diamond substance, in the form of tiny, thinner portions. These traces are harmless to the diamond so long as they remain in the Pavilion's top levels. "Naturals" will be written next to such a diamond on the certificate.
It's not a good idea to put rings with extremely thin or very thin Girdle in protruding locations since these areas are easily cleaved or chipped. Although these diamonds can be worn in earrings and pendants without any problems, there is a small chance that they could be chipped during the setting process. There is a substantial risk of damage during prong setting on diamonds with pointed edges that are Very thin, Very thin, or even Thin
Girdles that are Thick, Very Thick, or Very Thick add a lot of weight to a diamond, limiting its ability to spread its wings. Yet, a diamond's brilliance is unaffected by a thicker girdle. Be wary of diamonds with Very Thick Girdles that were likely left that way for no other reason than to increase the diamond's overall mass. When carried in the Girdle, the extra weight serves no useful purpose.
For example, if the diamond is stated as having an Exceptionally Thick Girdle but is only just above a pricing threshold—say, 1.00 or 1.01 Carat—you should assume that the cutter bruted the diamond to get that weight. Perhaps if he'd just left it as a Medium or Thin, it would have cost you less overall.
