About this 0.51ct natural round diamond

This 0.51ct natural round sits in the half to three-quarter carat band, graded H colour (near-colourless) and FL clarity (flawless or internally-flawless), with a top-tier cut grade and certified by GIA 5543768504. Listed at 7 retailers as of October 30, 2026, with prices from $1,427 to $3,771, a $2,344 spread on the same certified stone. NZ Jewellers lists it at $3,771. 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.
