Round Diamond

High On Brilliance And Fire

A Round Diamond is an eternal beauty! Its unique traditional cut combined with incredible brilliance steals hearts of many diamond enthusiasts all over the world.

The first ever natural rough Diamond which was given the shape of a round cut diamond was discovered at the Letseng Mine in Lesotho in the early eighteen century. The next one – the Cullinan Diamond- a true brilliant cut round diamond of 3106 carats was crafted in 1905. The famous Koh-i-Noor diamond – a masterpiece of art- was another round diamond weighing 478 carats. It was one of the largest round diamonds in the world and celebrated an Indian legacy. Later, during 1919, round diamonds gained popularity when Marcel Tolkowsky proposed a model of ideal diamond cut techniques and proportions, giving birth to the most sought-after round cut diamond shape. Following Tolkowsky’s expert craftsmanship, round diamonds are shaped in two broad forms with distinctive facets- the step-cut with a set of “staircase” facets and the brilliant cut featuring several triangular facets.

The exquisite shape and the brilliance of its contour may cost you a million! There can be naturally-bred diamonds shaped up to an excellent brilliant-cut round diamond. Else, you may obtain synthetic round diamonds which are comparatively less expensive. Diamond connoisseurs may also check out fancy colored round diamonds. There are different vibrant hues and shades including pink, purple, yellow, blue, green, and even red. Last but not the least, whenever you go out for shopping diamonds, have a good understanding of the Four C standards. The actual price and quality of a good diamond are assessed on the basis of its cut, clarity, color and carat weight.

Today, round diamond has carved a niche for itself in the contemporary diamond jewelry segment as well. Shaping of a diamond, no doubt, depends on personal tastes and preferences for jewellery. But a round diamond tops the popularity chart because of its all-round radiance with a blush of romance! Win the heart of your lady love with a round diamond solitaire. It would certainly add glitters to your love life!

Among the most preferred Diamond Cuts like emerald cuts, princess cuts, Asscher cuts and some sparkling silhouettes like oval, rectangular, pear shapes, heart shapes, etc, the round diamonds hold the highest appeal when designed for engagement rings, wedding rings, pendants, bands and trinkets.

To Bring Out A Perfect Cut

Diamond Cutting is a highly-specialized scientific process that changes a rough diamond to a multifaceted gemstone. The process of cutting diamonds involves high-end proficiency and technical know-how, state-of-the-art tools and a team of expert craftsmen to bring to the surface the beauty of these precious stones from rough and irregular shaped natural diamonds. Depending on various shapes and sizes, diamonds undergo specific cuts that comprise a set of characteristics including width, depth, girdle, table, crown, pavilion, etc. A proper Cut of a diamond also determines various levels of its light performance including fire(dispersion), scintillation, brightness, etc.

With the advent of the new ‘Point Cut’ technique in the last half of the 13 th century, the world experienced a simplistic method of diamond cutting for the very first time. A Point Cut Diamond featured a four-sided, octahedral crystal that later transformed into several other cuts or variations like the single cut, table cut, Old European cut, Old Miner and the most recent, the brilliant cut. Undoubtedly, diamond cutting involves considerable amount of patience, expertise and creative acumen to craft, develop and transform the nature’s hardest material into an incredibly beautiful gemstone. In addition, a careful consideration should be given to bring out the beauty with respect to the best Four C standards, without compromising on the material wastes while cutting as well as minimizing production costs.

Diamond cutting involves four broad steps of development:

• Marking: The process which determines the directions of cleavages and grains in the raw crystals and marks the points of imperfections which are supposed to be cleaved or chopped. A correct examination of each such points in a diamond crystal thus is crucial to obtain a perfect cut and to yield the highest value.
• Planning: In this phase, the desired size and the relative value of a specific cut are assessed.
• Cleaving or sawing: the process by which diamonds are either cleaved manually or sawed with a rotary saw or by a laser.
• Bruting and Girdling: a rotary lathe is used now to create facets on the diamond crystals. Gradually a rough stone is transformed into a cone-shaped diamond with rounded outlines.
• Polishing: It is the final stage of diamond cutting. Here, each crystal is faceted in the beginning through the ‘blocking’ technique and then undergoes ‘polishing’ via ‘brillianteering’. Thus the diamond gets its sheen, fire and brilliance.

The American Gem Society Laboratory (AGS) has also developed a set of cutting standards for some specific Diamond cuts like the round cut and the princess cut. Following their set guidelines, diamond cutting has been further graded, depending on several factors like polish, proportion, light performance and symmetry. These Cut Grades are as follows:

• Elite Ideal Cut Grade
• Excellent Cut Grade
• Very Good Cut Grade
• Good Cut Grade
• Fair Cut Grade
