About this 0.49ct lab-grown marquise diamond

This 0.49ct 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 LG743518052 or 743518052. Listed at 20 retailers as of October 29, 2026, with prices from £166 to £830, a £664 spread on the same certified stone. MOH London lists it at £830. 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.
