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 7411719644. Listed at 17 retailers as of October 30, 2026, with prices from $1,723 to $5,215, a $3,492 spread on the same certified stone. NZ Jewellers lists it at $5,215. 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.
