About this 0.51ct natural oval diamond

This 0.51ct natural oval 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 7551678602. Listed at 20 retailers as of November 4, 2026, with prices from $1,197 to $4,067, a $2,870 spread on the same certified stone. NZ Jewellers lists it at $4,067. 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.
