Five Gemstone Ring, 18ct Gold. The centre Ruby in the above ring is a good strong red in colour, and is a good example of this precious gemstone, but it is centred in this cluster ring, really, to set off the adamantine sparkle of the surrounding four rose cut Diamonds.
The “rose” cut is an old cut, where the gemstone is facetted all across the top, the back usually being flat. As the cutting of Diamonds became ever more sophisticated from the dawn of the Industrial Age in the 1700s, with tools ever more precise, a sharper brilliance was achieved with side facets around a flat face, with a facetted triangular “pavilion” underneath, and the “rose” cut grew out of fashion.
Now there is only one Diamond cutting centre in the world still creating rose cuts, on the west coast of India.
