How to Evaluate Loose Diamonds (Loose Diamonds)

(Loose Diamonds)

Loose diamonds are easier to evaluate as a set, because the absence of a setting gives you access to all aspects and facets of the stone. While the factors that lead to a Diamond's quality are the same, regardless of whether the stone is set, the assessment is a little easier when you do not have to work to a setting. While you should normally have a licensed jeweller, estimated expert or gemologist consider before buying diamonds, you get a fairly good idea of the quality of the stones of them carefully examine both with the naked eye and under the microscope.

Step 1
Check the color. Except in the cases of "fancy" colored diamonds, the clearer a diamond, the better the quality of the stone. You can check this by running it under a bright light. If the stone seems cloudy, milky, or has a yellow or brown cast, then the diamond is not of particularly good quality.

Step 2
Look for dark spots. When viewed from above, a diamond should be bright and sparkling wine. While most diamonds have flaws, a good diamond cutter can generally be reduced so that the facets of obscure majority of the inclusions overhead view. If there is visible dark spots in the diamond, the cut was either sloppy or inclusions were too big to hide - either as the stone is of inferior quality.

Step 3
Check the facets and angles. Diamonds are used to many extremely hard substances because of their ability, an edge. Facets and the port authorities of the facets should be very sharp and clearly defined. If they are rounded or worn, you can with a fake, because nothing can be a point like a diamond.

Step 4
Verify that all incusions. If a flawless diamond appears, you must necessarily, with at least one licensed jeweler. Fake diamonds have no pockets, so if a deal seems too good to be true, then it probably is. You should be able to determine a diamond through the unique locations and type of inclusions. Large inclusions, with the naked eye visible decline in the value of a piece dramatically, while smaller inclusions visible only under a microscope or magnifying glass are generally less of a problem.

Step 5
Award of the "fire". A Diamond's "fire" or brilliance is the reduction in diamond and the interior prismatic functioning of the stone. If the stone does not blink when it is exposed and moved under bright light, then it is of lower quality than a stone, sparkles.
