About this 1.51ct natural marquise diamond
This 1.51ct natural marquise sits in the one-and-a-half to two carat band, graded H colour (near-colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade stated by the retailer rather than the lab and certified by GIA. Compare the cross-retailer prices above before buying. The same certified stone often varies 15 to 40% across stores.
