About this 0.45ct natural round diamond

This 0.45ct natural round sits in the sub-half-carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by GIA 6505285170. Listed at 19 retailers as of October 26, 2026, with prices from $1,192 to $3,993, a $2,801 spread on the same certified stone. NZ Jewellers lists it at $3,993. 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.
