About this 0.8ct natural cushion diamond

This 0.8ct natural cushion sits in the just-under-one-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 6435832188. Listed at 13 retailers as of November 6, 2026, with prices from £690 to £1,503, a £813 spread on the same certified stone. Flawless Fine Jewelry lists it at £1,503. 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.
