Both gemstones and diamonds can be cut in round, rectangular, or oval. There were others who made the ring much later and added jewels and an intricate crown design. The basic design of the ring has not changed but now there is more intricacies in the crown, gemstones or jewels can be used to fashion the heart, and the hands are simply hands.
Explanation of Cut, Color and Clarity of This Diamond
Cut Quality The ideal cut diamond is a very precise mathematical equation, where diamond proportions and angles are cut to optimize the diamond's superlative optical properties, in particular it's high refractive index and color dispersion, to create a diamond of unequaled beauty with perfect balance of brilliance and fire. In layman's terms, the diamond is cut to make it the most beautiful diamond so it retains its intrinsic value.
Color Diamonds of D color are absolutely colorless. It is the top most color grade and only 0.3% of all diamonds that make it out of the earth being D color.
Clarity Diamonds of SI3 clarity are on a borderline between slightly included and included diamonds. SI3 grade inclusions are almost obvious under 10x magnification. Inclusions in such diamonds may be noticeable to the unaided eye. However, when observing the diamond "face up" as it is mounted in a ring, the inclusions are usually not visible.
