About this 0.51ct natural round diamond

This 0.51ct natural round sits in the half to three-quarter carat band, graded G colour (near-colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by GIA 6535658485. Listed at 23 retailers as of November 6, 2026, with prices from $1,259 to $5,294, a $4,035 spread on the same certified stone. NZ Jewellers lists it at $5,294. 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.
