About this 0.31ct lab-grown princess diamond

This 0.31ct lab-grown princess sits in the sub-half-carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG689508897 or 689508897. Listed at 16 retailers as of October 27, 2026, with prices from $121 to $1,261, a $1,140 spread on the same certified stone. MOH London lists it at $1,261. 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.
