This 1.25ct lab-grown cushion sits in the one-and-a-quarter to one-and-a-half carat band, graded D colour (colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG845615585 or 845615585. Listed at 16 retailers as of October 30, 2026, with prices from £259 to £1,154, a £895 spread on the same certified stone. Reve Diamonds lists it at £1,154. Cut grade matters more than carat or clarity for visible brilliance. If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
