About this 0.42ct natural radiant diamond

This 0.42ct natural radiant sits in the sub-half-carat band, graded D colour (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 6561203790. Listed at 9 retailers as of November 4, 2026, with prices from $1,593 to $2,743, a $1,150 spread on the same certified stone. Flawless Fine Jewelry lists it at $2,743. 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.
