About this 0.46ct lab-grown marquise diamond

This 0.46ct lab-grown marquise sits in the sub-half-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG841678904 or 841678904. Listed at 13 retailers as of November 1, 2026, with prices from $247 to $1,046, a $799 spread on the same certified stone. MOH London lists it at $1,046. 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.
