About this 0.77ct natural round diamond

This 0.77ct natural round sits in the just-under-one-carat band, graded J colour (near-colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI 810634313. Listed at 20 retailers as of October 25, 2026, with prices from $755 to $2,566, a $1,811 spread on the same certified stone. NZ Jewellers lists it at $2,566. 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.
