When you submit your diamonds to the EGL, the European Gemological Society, for appraisal you will receive a comprehensive report about every detail of the stone.
The laboratories, which are located in major cities of the world, appraise only loose stones, which is why the term EGL loose diamonds is often used to describe stones that have been appraised by these facilities.
Unlike IGI appraisals, the facilities will not grade or appraise any diamonds that have already been set in jewelry without removing the stones first.
In order to insure your diamond and make sure that you have best value diamonds it is essential that you have an appraisal report.
Insurance companies do require this document in order to sell you a policy.
You will also find out if you got the best value diamonds.
You can get a refund with money back guarantee diamonds if the IGI appraisals come back with less than the price you paid.
The report of your EGL loose diamonds will give you a diagram of the stone with an easy to read explanation.
In grading the stones, the gemologists look at the depth of the diamond.
This can vary according to the way in which the diamond is cut.
The depth can give the illusion of the diamond being larger than it actually is and can determine the amount of light it reflects on the facets of the stone.
If a diamond is too shallow, it will not reflect very much light and will therefore not have the brilliant shine that you would like it to have.
A diamond with a depth of 59.
3% is regarded as being a good diamond with a good depth rating.
There are many cuts that will give you this depth, but according to the specialists in grading EGL loose diamonds, the best cut is known as the Tollowsky's cut.
This cut reflects the light to allow the diamond to show the maximum amount of brilliance.
The measurement across the top of the stone is known as the diamond table.
This is another important aspect of EGL loose diamonds.
The brilliance of the diamond is also influenced by this; in the amount of sparkle you see when you move the diamond, especially when it is set in a ring.
A diamond with a small table will not have the fire and brilliance of one that has a large table, even though the smaller stone may be more expensive.
When you want to buy EGL loose diamonds it is important to become familiar with the terminology related to the facets.
The Round Brilliant Cut is a very common diamond cut and has 58 facets.
This cut is just one example in which several different terms apply, which are: oTable facet: this is the top of the diamond and should be octagon shaped oStar facets: these are below the table facet and have eight points like a star oKite or Bezel facets: these extend downwards from the table facet and have four sides shaped like a kite oGirdle facets: these are attached to the kite facets and the girdle of the diamond.
There are both upper and lower girdle facets.
oPavilion facets: they are connect on the underside of the girdle are located on the bottom of the diamond The girdle of a non conflict diamond that is graded by EGL loose stones can be of varying sizes from very thick to very thin; the girdles of best value diamonds fall somewhere in the middle of this range.
There are three different types of girdles, but there is really no specific type that will make one diamond more valuable than another.
