About this 0.46ct lab-grown marquise diamond

This 0.46ct 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 LG803664917 or 803664917. Listed at 16 retailers as of November 1, 2026, with prices from $240 to $1,175, a $935 spread on the same certified stone. MOH London lists it at $1,175. 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.
