About this 0.91ct lab-grown round diamond

This 0.91ct lab-grown round sits in the just-under-one-carat band, graded F colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG691537168 or 691537168. Listed at 19 retailers as of November 1, 2026, with prices from $303 to $1,501, a $1,198 spread on the same certified stone. MOH London lists it at $1,501. 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.
