Inspired by your multi-ethnic life,
we shape diamonds to share our wonderful tales…
Carat is a word that refers to the weight of a diamond. Prior to the 20th century, diamonds were measured using carob seeds, which were small and uniform and served as a perfect counterweight to the diamond. The word "carob” is the origin of the word "carat" that we use now.
The diamond size is proportional to its carat weight. When rough diamonds are cut and polished into finished diamonds, up to 55 to 65% of the total carat weight may be lost.
Since larger rough diamonds of high quality are found less frequently than smaller rough diamonds of high quality, a single 2-carat diamond will be more expensive than two 1 carat diamonds of the same quality.
A diamond will increase in weight much faster than it increases in actual "face-up" diameter view. For ex, while an ideal cut 1-carat round diamond measures approx 6.5mm in diameter, a diamond of twice its weight measures only 8.2mm wide-less than a 30% increase.
A chemically pure and structurally perfect diamond is perfectly transparent with no hue, or color. However, in reality almost no gem-sized natural diamonds are absolutely perfect. The color of a diamond may be affected by chemical impurities and/or structural defects in the crystal lattice.
To understand diamond clarity, we must first understand how diamonds are created. Natural diamonds are the result of carbon exposed to tremendous heat and pressure deep in the earth. This process can result in a variety of internal characteristics called ‘inclusions’ and external characteristics called ‘blemishes.’
Evaluating diamond clarity involves determining the number, size, relief, nature, and position of these characteristics, as well as how these affect the overall appearance of the stone. If you are trying to determine what is the best clarity for a diamond, remember that no diamond is perfectly pure. But the closer it comes to purity, the better its clarity.
A diamond cut is a style or design guide used when shaping a diamond for polishing such as the brilliant cut. Cut does not refer to shape (pear, oval), but the symmetry, proportioning and polish of a diamond. The cut of a diamond greatly affects a diamond's brilliance; this means if it is cut poorly, it will be less luminous.
Achieving the best cut for a diamond reflects in the stone’s final beauty and value. And of all the diamond 4Cs, it is the most complex and technically difficult to analyze. To determine the cut grade of the standard round brilliant diamond – the shape that dominates the majority of diamond jewelry – GIA calculates the proportions of those facets that influence the diamond’s face-up appearance. These proportions allow GIA to evaluate what the best cut for a diamond is, by studying how successfully a diamond interacts with light to create desirable visual effects, such as:
- Brightness: Internal and external white light reflected from a diamond
- Fire: The scattering of white light into all the colors of the rainbow
- Scintillation: The amount of sparkle a diamond produces, and the pattern of light and dark areas caused by reflections within the diamond
