About this 1.51ct lab-grown cushion diamond

This 1.51ct lab-grown cushion sits in the one-and-a-half to two carat band, graded E colour (colourless) and VS2 clarity (very-slightly-included) and certified by IGI LG722537197 or 722537197. Listed at 14 retailers as of October 29, 2026, with prices from £172 to £1,351, a £1,179 spread on the same certified stone. Brilliant Earth lists it at £1,351. 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.
