About this 0.51ct natural radiant diamond

This 0.51ct natural radiant sits in the half to three-quarter 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 1567123776. Listed at 15 retailers as of October 30, 2026, with prices from $1,053 to $3,587, a $2,534 spread on the same certified stone. NZ Jewellers lists it at $3,587. 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.
