The oval shaped or cut diamond dates back to the 60s when Lazare Kaplan developed it. Perhaps its a close alternative to the round cut and can emit as impressive sparkle as well. Its length to width ratio will be important and you may want to compare a few different ones to see which best suites your taste. For instance look at 1.25 compared to 1.5 vs. 1.75.
With an oval dimaond its pertinent to have at least a good cut. The clarity is sufficient with SI2 but go with better if possible. As far as depth goes its important to be in the 54-70 range (but 58-66% if you can). With the table choose in the range of 53 to 68%. As far as color is concerned I or better is sufficient. Oval cut diamonds are also subject to the bow tie effect (what looks like there is a dark area inside of the stone that has the form of a bow tie). This shape of rock can be a nice alternative to a round stone. Classic cantik indah anggun dan elegant dengan batu permata berlian berbentuk Oval Cut ,
