About this 0.82ct lab-grown cushion diamond

This 0.82ct lab-grown cushion sits in the just-under-one-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG850686835 or 850686835. Listed at 5 retailers as of November 4, 2026, with prices from £432 to £1,175, a £743 spread on the same certified stone. Riddles Jewelry lists it at £1,175. 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.
