About this 0.51ct natural round diamond

This 0.51ct natural round 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 and certified by GIA 6565395319. Listed at 21 retailers as of November 4, 2026, with prices from $2,026 to $6,600, a $4,574 spread on the same certified stone. NZ Jewellers lists it at $6,600. 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.
