About this 0.45ct lab-grown marquise diamond

This 0.45ct lab-grown marquise 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 LG807610392 or 807610392. Listed at 17 retailers as of October 30, 2026, with prices from $335 to $1,640, a $1,305 spread on the same certified stone. MOH London lists it at $1,640. 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.
