All about ROSE CUT DIAMOND

The rose cut was one of the early or antique diamond shapes.
It was so named because it resembled a rose bud just before it had opened with the facets resembling the tightly packed rose bud petals.

HISTORY
The rose cut diamond was believed to have been introduced in European cities in 152.
It is thought by some that the rose cut may have had ancient Indian origins because famous old Indian diamonds, such as the Sancy, featured a rose-like cut and are of indeterminate age and origin.
Although the rose cut was ostensibly swept aside by the more modern brilliant cuts, there has been something of a curious revival of interest in the rose cut diamond in America in recent times. Perhaps this is in part due to their scarcity; perhaps due to the modern taste for the exotic and antique. Some cutters in India, the center of the world's diamond cutting industry, have revived the rose cut. However, many of these roses are created as replacement gemstones for antique jewelry.
True antique rose cut diamonds have become scarce and valuable.

CHARACTERISTICS
Rose cuts look like diamonds which have been cut upside-down, they rise to a point at the top, they are often flat at the base and forms a hemisphere or low pyramid above, covered with small facets.
The crown is domed shaped and the facets meet in a point in the center.
The facets are in two rows:
Those in the upper row are called star facets; those in the lower diagonal facets. In the centre, there are generally six facets of triangular shape.
The two most famous diamond cutters of this time were Giacomo Tagliacarne Giovanni delle Corniole who perfected the art of facetted gem cutting.
A circular stone is best for the Rose the facets being more effectively brought out, and more easily polished than in a flat-shaped stone.

NAMES
Other names for the Rose Cut are the Rosette, Antwerp Rose (Roses d'Anvers), Dutch Cut, Crowned Rose Cut, or the Full Holland Cut. The Dutch references in the names reflect the fact that Holland was once the capital of the diamond-cutting world.

THE CUTTING PROCESS
Diamond Facets are the smooth surface areas of a diamond which are cut and polished to control the brilliance and the durability of a diamond.
A skilful diamond cutter brings out all the brilliance and sparkle of a diamond by choosing the most appropriate cut, such as the Ascher Diamond cut.

VALUE
What constitutes good cuts?
Good Rose Cut Diamonds are effected by several different elements which have a large impact on a diamond's brilliance. These include the Width and Depth of the stone, the diamond Clarity, the Symmetry and the alignment of a diamond's facets and the polish.

The "GREAT MOGUL" - a Famous Rose Cut Diamond
One of the most famous rose cut diamonds of all time was undoubtedly the Great Mogul. This was described by Tavernier, the French traveler, who had seen it in 1665 in Hindustan.
At the time of viewing, it was said to weigh 280 carats, but to have been cut from a rough stone of 787.5 carats.
The fate of the Great Mogul is not known to history, some have thought that it is now amongst the treasures of the Shah of Persia under the name of “Darya-i-Nur,” or "Sea of Light.”But some evidences tend to prove that the “Darya-i-Nur” is certainly a different stone.
It is believed either to have been lost or cut into smaller stones.
Its present location is unknown, and some believe that either the Orlov diamond or the Koh-i-noor may have been cut from this stone after its loss following the assassination of its owner, Nāder Shāh, in 1747.
