About this 0.47ct lab-grown marquise diamond

This 0.47ct lab-grown marquise sits in the sub-half-carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG817625561 or 817625561. Listed at 16 retailers as of November 4, 2026, with prices from £250 to £1,047, a £797 spread on the same certified stone. Riddles Jewelry lists it at £1,047. 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.
