Diamonds

I. Introduction

Diamond is the birthstone of April and; anniversary gemstone for the 10th and 60th years of marriage.
The Diamond was discovered in 500 B.C. in India. The word “diamond” comes from the Greek word “adamas” which means unconquerable – suggesting the eternity of love. Since ancient Greece, diamonds have been the traditional symbol of love. The ancients believed they were hardened dew drops, splinters from the stars or crystallized lightening.

The diamond, the hardest substance known to man, is a crystallized carbon which has unique powers of light reflection. Because it is composed of a single element, the diamond is the purest of all gemstones. Diamond is a colorless stone. Some other occasional colors are blue, yellow, amber, red, green, pink.

II. The value of a diamond, the 4 Cs: Cut – Clarity – Color – Carat Weight

Cut

Cut is the factor that determines the brilliance (quality) of a diamond. A classic round brilliant cut diamond has 58 facets – 33 on the top, 24 on the bottom and the culet (1 point at the bottom – another tiny facet). Each of the stones’ facets must be placed by the diamond cutter in exact geometric relation to one another. Quality diamonds must be properly cut and not “spread,” which means that the proper proportions are compromised to make the stone weigh more.

Clarity
The fewer the inclusions, the clearer, more brilliant and more expensive the diamond. A flawless diamond means that no inclusions can be seen under a 10x jeweler’s loupe. Flawless diamonds are extremely rare.


Color
The more colorless the diamond, the more valuable it is. Although most diamonds may appear colorless to the eye, the majority contain slight traces of yellow or light brown. Depending on the stone’s size, a single increase in color grade can boost the value of a diamond by thousands per carat. A traditional engagement diamond is colorless or near colorless.

In nature diamonds can also occur in shades of red, pink, blue, green and deep yellow. They are called “Fancy diamonds”.


Weight
Standard measure of a diamond’s size is called carat(ct) weight.
Size alone is almost meaningless unless you consider cut, clarity and color. A large stone is not very valuable if it lacks brilliance, purity and high-grade color. For the reason that large stones are harder to find than small ones, the diamond size does increase its value. No two diamonds are exactly alike and a reputable jeweler can help you weigh all of the factors – color, cut, clarity and carat weight.
