About this 0.45ct natural round diamond

This 0.45ct natural round sits in the sub-half-carat band, graded J colour (near-colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by GIA 1545578277. Listed at 17 retailers as of November 2, 2026, with prices from $853 to $3,186, a $2,332 spread on the same certified stone. NZ Jewellers lists it at $3,186. 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.
