About this 0.85ct lab-grown cushion diamond

This 0.85ct 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 LG764675320 or 764675320. Listed at 16 retailers as of November 1, 2026, with prices from £215 to £2,326, a £2,110 spread on the same certified stone. Do Amore Diamonds lists it at £2,326. 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.
