Ideal-cut ( Heart and Arrow diamonds) diamonds are cut too widely accepted proportions and angles. About 98% of a diamond’s brilliance is controlled by its cut. Hearts and Arrows diamonds are “supersymmetry ideal cuts”. The hearts and arrows pattern is only possible when exceptional symmetry exists. Symmetry is judged on the basis of the degree

here are some tips & tricks to identify natural diamonds additional tests to identify natural diamonds at home The Tilt Test When a proportional brilliant cut stone is illuminated & viewed against a dark background, with its table facet at 90°to the line of vision, the stone will appear uniformly bright. Now as the observer

Identification of natural Diamonds and its Simulants. Natural diamonds, either as loose gemstones or mounted in Jewellery, can be distinguished from their simulants in the following ways: 1): natural diamonds Examination by hand lens A diamond specialist should be able to recognize diamonds by using only an eyeglass. By using this, one can observe the

Diamond colour grading is a subjective process and decision made at length is usually less reliable than those reached more quickly. This is because the eyes tires quickly and the ability to grade accurately diminishes. In the context of diamonds, “diamond color” refers to the presence or absence of color in a diamond. The Gemological

diamond grading : The majority of polished diamonds seen today exhibit a particular tint of light yellowTruly colourless diamonds without any trace of color are so rare that they are difficult to obtain and are very highly valued. what is diamond grading?

Diamond clarity refers to the presence of internal and external flaws, or imperfections, in a diamond. These imperfections are called inclusions (internal flaws) and blemishes (external flaws). Clarity is one of the four Cs of diamond grading, along with carat weight, color, and cut. The clarity grade of a diamond is determined by the number,

purity diamonds is determined by five factors for each inclusion. These factors, which are given below, in the order of their importance, should be appraised as a whole rather than separately. Assigning the Clarity Grade of diamonds-purity diamonds a): NumberThe greater the number of inclusions, the poorer the grade. b): SizeThe larger the inclusions, the

DIAMOND GRADING FOR CLARITY Internal features and inclusions may light transmission through a diamond, decreasing its brilliance and its clarity. All characteristics found in or on a diamond can be divided into either: a) Internal characteristics: Inclusions totally enclosed by the host diamond and those react with the surface of the gem. b) External characteristics:
