Loose Diamonds – Education Guide

While evaluating the value of a loose diamond you need a good knowledge of 4 C’s— cut, clarity, color, and carat weight. They are basic criteria to ascertain the beauty and price of a diamond.

Cut: The amount of diamond removed from the rough diamond has a great impact on the overall look of the diamond. A perfect cut is a diamond that reflects almost all light that it comes in contact. In the industry, such a diamond is extremely stunning and rare to find.

Clarity: Clear diamonds without impurities are the most expensive ones. For instance FL or IF rating is given to those diamonds that are considered immaculate.

Color: The better the color grade, the whiter the diamond looks. Diamonds are classified on the basis of their color and are graded on a scale of D-Z. D is considered as the most favorable color, E is rare while F denotes superior quality. Anything below these grades will show a tint of yellow in the diamond’s body.

Carat weight: It refers to the weight of the diamond when they are measured on a scale.

Along with 4Cs, another criteria that helps in determining the worth of a diamond is certification. The Gemological Institute of America (GIA) and American Gem Society Laboratories (AGSL) both produces high-class diamond grading reports which are reliable and trustworthy.

Laser Inscribed For Proper Identification Purposes

Laser inscribed diamonds have been around for a long time now. It’s helpful to have the report number inscribed on a diamond because it gives a quick, easy, and accurate matching of that diamond to a grading report.

In the case of theft, it will also help in recovery. The downside is that it is possible for a diamond cutter to polish off a laser inscription easily.

Some companies also offer customized laser inscription of a phrase onto a diamond for an additional charge. You can really use your imagination here on what to write but these are the 2 memorable quotes that I had come across.

“Roses are red, Violets are blue, Is this diamond big enough for you?”, “Diamonds better be forever, it will take me that long to pay for it!”.

– Important Take Away Point –

If you buy a diamond with a laser inscription on it, you will want to make sure you can actually see the inscription after it’s been set into a mounting. I’ve seen cases where there the diamond setter ended up placing the inscription area under a prong and this can cause disputes with the client.

In many cases, this wasn’t anything that was done intentionally. The truth is, these inscriptions are difficult to see even with a 10X magnification and diamond setters typically only work with about 5 – 6X magnification. If they don’t know that the diamond they are setting has a laser inscription along the girdle, they could easily miss seeing it.
