About this 0.69ct lab-grown cushion diamond

This 0.69ct lab-grown cushion sits in the half to three-quarter carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade and certified by IGI LG657420238 or 657420238. Listed at 16 retailers as of November 3, 2026, with prices from £270 to £2,007, a £1,737 spread on the same certified stone. Do Amore Diamonds lists it at £2,007. 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.
