Many jewelers offer the option of purchasing loose diamonds instead of getting those already set in jewelries. These are offered both in stores and by online jewelry vendors. This allows consumers to buy the perfect jewelry for their loved ones or for themselves. Diamonds are graded by the Gemological Institute of American (GIA) based on the four Cs – Cut, Color, Clarity, and Carat. Are you having a hard time deciding on which loose diamonds to buy? Read on for some useful tips in purchasing loose diamonds.
1. Diamond Cut Quality
The cut of the diamond refers to its shape. It determines the diamond’s brilliance or the amount of light reflected. Therefore, this is often considered as the most important in the four Cs. Cut grades are not standardized across different vendors so choosing a cut quality can be quite tricky. An ideal cut will reflect the most amount of light through the top of the diamond. Symmetry or the alignment of a diamond’s many facets is a critical factor in the cut of a diamond. The light that enters the gem bounces from one facet to another before reflecting back to the viewer’s eye. This gives the diamond its maximum brilliance.
2. Diamond Color Grade
A diamond’s color has a serious effect on a loose diamond’s appearance and price. It is important to note that different shapes of the diamond reflect different colors and surprisingly, diamonds come in a wide array of colors. The most valuable are those that are completely clear or colorless. Others contain a slight tint of yellow. Diamond color are graded according to an alphabetical scale from D to Z, with D being completely colorless. As the grade approaches Z, the diamond shows more of a yellow tint.
3. Diamond Clarity Grade
Most diamonds contain imperfections, called inclusions, since these are formed deep within the earth under extreme heat and pressure. The clarity refers to the degree to which these inclusions are present. Diamonds that contain blemishes or inclusions have less brilliance. Avoid diamonds which have visible flaws that affect their overall beauty.
4. Diamond Carat Weight
The carat refers to the diamond’s size and weight. This is often confused with “karat” which is a term used to describe the quality of gold. As the carat of the diamond rises, so does its price. This is because the larger the diamond is, the more uncommon it becomes.
The best place to buy diamonds online is those that are GIA certified. GIA is considered as the most reliable and up to date standard in grading diamonds. By using the four Cs on GIA certified diamonds, you can ensure that you will get the best loose diamond for your money.
