Jewelry Dallas - What is GIA?

The Gemological Institute of America or GIA is the organization responsible for a standard grading system for determining diamond quality that is most widely accepted by professional diamond assayers and purveyors. Referred to as the 4Cs, this system considers color, clarity, cut and weight expressed in carats. Commonly, carat weight is considered the measure of an expensive diamond, but two diamonds of the same weight can vary widely in their values because of the other standard considerations. Because of this, only skilled professionals of jewelry Dallas can truly determine adiamond’s value. Many of the considerations are clear only with magnification.

Inclusions and Blemishes

Internal defects are called inclusions, and outside defects are considered blemishes. The least amount of inclusions will constitute a flawless diamond, but these clarity issues can be so slight even with magnification that they must be magnified by ten times to become visible. However, beyond color, this is one of the most important characteristics determining the quality of a specific diamond. Colors can range from colorless to light on a scale that ranges from D to Z alphabetically. A colorless D diamond should be absolutely clear like distilled water while Z color light diamonds are practically yellow.

Yellow is Light?

Color is one of the easiest characteristic to determine by amateurs beyond weight, but some variations can be very slight, but these variations can mean a significant difference in value. This too means that a professional should be consulted about a diamond’s quality, and thus, its price. Cut and weight are both significant factors in value, but by utilizing credentialed professionals, these can be the most standard qualities in diamonds of the jewelry Dallas purchasing process. Cut can be consistent as well as carat weight. However, these characteristics can determine the budgetary high and low points when considering which diamond is appropriate for the occasion and budget.
