Loose Diamonds

The first step of loose diamond shopping is a good understanding of diamonds and diamond prices. There are many factors that influence quality, value and prices of loose diamonds. Some you can control, others are based entirely on market conditions as well as supply and demand.

While selecting loose diamonds you should know the basics of the diamond characteristics. The first thing you need to know about diamonds is that they should be purchased according to the ‘Four Cs’: carat, clarity, color and cut. Mind that cut is very different from the shape of a diamond. Shape refers to the overall appearance of a diamond, such as round, pear, oval, square, rectangular, or heart-shaped diamonds. Cut refers to the facets cut into a diamond that give it the ability to catch and reflect light for sparkle. ‘Four Cs’ knowledge is crucial before purchasing any loose diamond.

Besides, you should also have an overview of diamond terminology, diamond fluorescence, diamond enhancements, shapes of diamonds, and explains diamond grading reports. Good understanding of diamond characteristic and knowing which questions to ask when purchasing a diamond are instrumental when you are ready to make diamond investment.

Loose Diamonds Grading

The DiamonDAD.com provides you with the information on "how to buy a loose diamond." This site outlines the important information of diamond basics such as cut, color, clarity, carat weight, total depth, pavilion, culet, fluorescence, symmetry, and polish.

Loose Diamond Cut - Many claim that cut is, in fact, a diamond’s most important feature. The beauty of a diamond depends largely on its optical properties.

Loose Diamond Color - Most commercially available diamonds are graded according to their purity or whiteness. Colorless diamonds are the most desirable because they allow the most sparkle. With the exception of fancy colored diamonds, the more colorless the stone, the higher it’s grading and value.

Clarity - Clarity the degree to which a stone is free from external marks called blemishes and internal features called inclusions. The uppermost grade is ‘FL’ (flawless), the lowest, ‘I3’ (imperfect eye-visible inclusions).

Carat Weight - The weight of a diamond is measured in carats. One carat equates to200 milligrams, or 0.2 grams.

Table Width - Table width is quoted as a percentage of the average width of the diamond's girdle.

Total Depth – The higher the total depth percentage, the more amount of brilliance a diamond will display.

Culet - The point on the bottom of a diamond's pavilion is called a culet.

Pavilion - The pavilion is the bottom portion of the diamond, below the girdle.

Symmetry - Symmetry is graded as Excellent, Very Good, Good, Fair or Poor according to a GIA certification.

Polish - Polish is graded the same way as symmetry.

Fluorescence - Roughly one third of diamonds available in the market fluoresce. Fluoro can be faint to very strong.

Diamond Prices

Diamonds pricing is a complex and elaborate process that requires the consideration of many factors. Diamond prices are mainly determined by:

  • - The cost of mining and sorting the rough diamond.
  • - The cost of cutting the loose diamond.

However there are other costs necessary to manufacture the rough stone into a ready diamond. A very important stone may be certified and graded by an independent company in accordance with the ‘Four Cs’: carat, color, clarity, and cut.
