About this 0.66ct natural round diamond

This 0.66ct natural round sits in the half to three-quarter carat band, graded I colour (near-colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by GIA 6532912005. Listed at 11 retailers as of October 27, 2026, with prices from $1,358 to $3,592, a $2,233 spread on the same certified stone. NZ Jewellers lists it at $3,592. 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.
