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), with a very-good cut grade and certified by IGI LG842631451 or 842631451. Listed at 16 retailers as of October 30, 2026, with prices from £172 to £907, a £734 spread on the same certified stone. Reve Diamonds lists it at £907. 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.
