Diamond clarity is the quality of diamonds that relates to the existence and visual appearance of internal characteristics of a diamond called inclusions, and surface defects, called blemishes. Clarity is one of the four Cs of diamond grading, the others being carat , color , and cut .
Once again, we can see that Tolkowsky's predictions are helpful in explaining optimal diamond performance, but they are incomplete by today's [2001] technological standards. [8] Figures 1 and 2 show the facets of a round brilliant diamond. Figure 1 assumes that the "thick part of the girdle" is the same thickness at all 16 "thick parts".
One major advantage of the artificial opening bid of 2 ♣ for all types of strong hands is that other opening bids at the two-level (2 ♦, 2 ♥ and 2 ♠) become available for weak two bids, thus eliminating many possible bids for the opponents. These weak two hands appear 20 times as often as the very strong hands, which illustrates the ...
The clarity, or purity, of a diamond refers to internal inclusions of the diamond, and is one of the 4-Cs in determining a diamond's value.Common inclusions that appear inside diamonds are black carbon spots and small cracks, commonly referred to as fractures or "feathers", due to their feathery whitish appearance when viewed from above or through the side.
Diamond reports from GIA (as well as other, for-profit sources) are now demanded by most consumers purchasing diamonds over a certain size, typically for over 0.5 carat (100 mg), and almost always for over 1.0 carat (200 mg), and are considered an important tool in guaranteeing that a diamond is accurately represented to a potential buyer.
Amid the AI boom, Element Six has found fresh interest in its creations. Diamonds can inherently handle high levels of heat, which can help power electronics, potentially amplifying the stone’s ...
Fire refers to the spectral colors which are produced as a result of the diamond dispersing the white light. Scintillation refers to the small flashes of light that are seen when the diamond, light source or the viewer is moved. A diamond that is cut and polished to produce a high level of these qualities is said to be high in light performance.
Diamond cutting, as well as overall processing, is concentrated in a few cities around the world. The main diamond trading centers are Antwerp, Tel Aviv, and Dubai from where roughs are sent to the main processing centers of India and China. [3] Diamonds are cut and polished in Surat, India and the Chinese cities of Guangzhou and Shenzhen. [4]
