About this 0.55ct natural round diamond

This 0.55ct natural round sits in the half to three-quarter carat band, graded H colour (near-colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by GIA 1545665189. Listed at 18 retailers as of October 30, 2026, with prices from $1,383 to $4,098, a $2,716 spread on the same certified stone. NZ Jewellers lists it at $4,098. 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.
