About this 0.55ct natural round diamond

This 0.55ct natural round sits in the half to three-quarter carat band, graded K colour (faint-tinted) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI 772655361. Listed at 5 retailers as of November 2, 2026, with prices from $550 to $1,742, a $1,192 spread on the same certified stone. MOH London lists it at $1,742. 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.
