About this 0.78ct natural round diamond

This 0.78ct natural round sits in the just-under-one-carat band, graded K colour (faint-tinted) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by GIA 6495077488. Listed at 5 retailers as of November 4, 2026, with prices from $1,486 to $3,926, a $2,440 spread on the same certified stone. NZ Jewellers lists it at $3,926. 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.
