About this 0.42ct natural heart diamond

This 0.42ct natural heart sits in the sub-half-carat band, graded F colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade stated by the retailer rather than the lab and certified by GIA 6505540729. Listed at 18 retailers as of November 2, 2026, with prices from $1,658 to $4,683, a $3,025 spread on the same certified stone. NZ Jewellers lists it at $4,683. 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.
