About this 0.51ct natural cushion diamond

This 0.51ct natural cushion sits in the half to three-quarter carat band, graded I 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 2547430629. Listed at 10 retailers as of November 1, 2026, with prices from €478 to €1,291, a €813 spread on the same certified stone. Flawless Fine Jewelry lists it at €1,291. Flawless clarity in sub-one-carat stones is rarely visible to the naked eye over VS1, so you are paying a meaningful premium for grade rather than appearance.
