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 LG847690068 or 847690068. Listed at 11 retailers as of October 31, 2026, with prices from £196 to £825, a £629 spread on the same certified stone. Riddles Jewelry lists it at £825. 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.
