About this 0.46ct lab-grown cushion diamond

This 0.46ct lab-grown cushion 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 LG786619078 or 786619078. Listed at 10 retailers as of November 1, 2026, with prices from £238 to £826, a £588 spread on the same certified stone. MOH London lists it at £826. 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.
