About this 1.27ct lab-grown cushion diamond

This 1.27ct lab-grown cushion sits in the one-and-a-quarter to one-and-a-half carat band, graded E colour (colourless) and VVS2 clarity (very-very-slightly-included), with a standard cut grade and certified by IGI LG804674389 or 804674389. Listed at 18 retailers as of October 28, 2026, with prices from £230 to £1,075, a £845 spread on the same certified stone. Reve Diamonds lists it at £1,075. 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.
