What is diamond?

It’s always advised before making a purchase that you have the basic understanding of the points to consider when buying a Diamond. Jewel One defines the four C’s , which is – Cut, Color, Clarity and Carat.


Color

Colorless Diamonds are quite hard to find. They are beautiful and highly prized.
The diamonds have an almost unperceivable tint of colors. The various degrees of color tint seen are assigned a letter from D-Z, denoting its position on the Diamond color scale. This scale shows the purest white color of D, to the yellowed tints of Z.

• D, E, F.
These purest tints are rare and comparatively expensive. Their rarity color assigns them a higher market price.
• G, H, I. Often offering much better value, to the untrained eye they seem the exact same color as the more expensive D, E and F colors.
• J, K, L. Discounted for their barely perceivable yellowish tints, Diamonds in this range offer excellent value.
• M - Z. Further discounted for their more distinct yellow hues.


Cut

The Round Brilliant Cut Diamond Accounts for over 90% of diamond sales worldwide. Although the Diamond appears round, there are many other beautiful Diamond cuts that warrant serious consideration. The eight most popular diamond cuts are displayed below

Carat weight

The weight of Diamond is measured in Carats. The unit of measurement originates from the traditional use of carob seeds to weigh Gemstones. Carob seed were used because of their consistent size and shape. The term carats is often confused with “Karats”. “Karat” is a measurement of purity of Gold. Diamonds are cut uniformly to ideal maximum Brilliance; Sparkle, and Fire. With this uniform cutting and proportions, we can very conveniently and accurately equate Diamond Carat Size with their millimeter weight.


Round Brilliant Cut Diamond

0.01 Ct 0.03 Ct 0.10 Ct 0.25 Ct 0.50 Ct 0.75 Ct 1.00 Ct 1.25 Ct 1.65 Ct


The price of the Diamond increases with its Carat weight. Large Diamonds are always rarer than smaller ones, so Carat prices rise considerably.


Clarity

Inclusions in the diamonds are tiny natural features within the body. Nearly all Gemstones contain some inclusions, however many are microscopic and can only be glimpsed under magnification. If inclusions do not interfere with the Brilliance, Sparkle and Fire seen by the passage of light through the Gem, they do not affect the beauty or value.

Clarity in Gemstones is determined by judging both the amount and location of inclusions.
Clarity affects both the beauty and value of the diamonds. The higher the clarity grade assigned from the list below, the higher the value.
