Diamonds Knowledge

Invented in the late 14th century, the Single Cut Diamond (also known as eight cut (8/8 cut diamonds) has the addition of corner facets to the earlier point cut. This creates an octagonal girdle, an octagonal Table, eight bezel or Crown facets, and eight Pavilion facets. Historically poorly cut Single Cut Diamonds were used as full cut replacements for smaller Diamonds. Modern single cut have a round outline and are used in the finest jewelry pieces and luxury watches. A great majority of Single Cut Diamonds are consumed by the watch industry for use in dials and hands of expensive upscale watches. In sizes smaller than 1.20 mm, single cuts produce better scintillation and fire due to their larger facets. They are precision cut and command a relatively high price. Single cut diamonds are commonly used in finest micro pavé pieces. Single cuts were mostly used in jewelry as substitutes of full cut stones. Every full cut diamond has a stage in the cutting process when it i

Marquise shaped diamonds can help to elongate the look of a finger when it is mounted on a ring setting. The fingers will appear slimmer and more slender. The shape of a marquise diamond can also maximise its carat weight, giving you a much larger-looking diamond. This  brilliant-cut  diamond looks beautiful when set just by itself, or with round or pear-shaped side stones. The desirable length-to-width ratio of a marquise shaped diamond is between   1.75 and 2.25. Marquise Cut Diamonds

Emerald cut is unique in its pavilions, which are cut with rectangular facets to create a unique optical appearance. Due to its larger, open table, this shape highlights the clarity of a diamond. If you choose an emerald-cut with a lower clarity grade, such as SI, be sure to review the clarity reference diagram on the diamond certificate. Emerald-cut diamonds can also vary greatly in how rectangular they are. If you prefer an emerald cut with a squared look, try to look for an Asscher-cut diamond instead.  For a classic emerald-cut shape, look for emerald cut diamonds with length-to-width ratios from somewhere between 1.30 and 1.40.  Emerald Cut Diamonds

The modified brilliant-cut  pear shaped diamond  is a combination of a round and a marquise shape, with a tapered point on one end. The diamond is always worn with the narrow end pointing toward the hand of the wearer. Like marquise and oval cuts, the pear shaped diamond comes in a variety of slim to wide cuts, and has the added benefit of making the wearer's fingers appear longer and slimmer. Ideally, a pear shaped diamond should possess excellent or very good symmetry. The point should line up with the apex of the rounded end. The shoulders and wings (the upper and lower curves on the right and left side of the diamond) should form uniform, symmetrical curves, with no straight edges. The rounded top should not appear narrow or squat, but like a semi-circle. In a misguided effort to add weight to a diamond (by incorporating more of the rough stone in the final cut) cutters may give the diamond added girth near the point or top, giving the diamond a squared off or squatty

The  princess cut  is the second most popular  cut  shape for  diamonds , next to a  round brilliant .The  Princess cut diamond  is a "fancy" (i.e. non-round shaped)  brilliant cut  - and is either exactly square or slightly rectangular when viewed from directly above the crown. Princess cut diamonds also tend to have a slightly lower price-per-carat than round cut diamonds. This is because the four sided pyramid shape of the princess cut diamond is similar to one half of the octahedron rough stone from which a princess diamond is cut. This similarity allows two equally sized princess cut diamonds to be cut from the same rough stone with relatively little waste (roughly 60% of the weight of the original rough stone is retained after cutting). The greater efficiency, or yield, translates to a lower price. Carat for carat, the crown surface area of a princess cut is about 10% less than a same-weight round diamond. However, the corner to corner measure of a princess cut

Single Cut Diamonds You may have heard the term  Single Cut Diamond  or  Eight Cut Diamond  and if you’re wondering what it is, you’re not alone because most people (and some jewellers) have never heard of them either. Single cut diamonds are also known as 8/8 diamonds or eight cut diamonds because they have 8 facets on the table and 8 facets on the pavilion. single cut diamonds A single cut on the other hand is a simple form of cutting a round diamond with only 17 or 18 facets. If you compare a Single Cut Diamond (usually small Carat Weights of 1.2mm or less), to a Full Cut Diamond (58 facets), you’d quickly see the difference. Small high quality single cut diamonds are highly prized especially in the watch industry, and because there are fewer but larger facets, they give off a majestic dance of light and colour, that is often lost in a sea of white light with the full cut stones. Single cut diamonds are sought after for high-end micropave settings. Typicall
