This 1.51ct lab-grown cushion sits in the one-and-a-half to two carat band, graded H colour (near-colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG846691579 or 846691579. Listed at 2 retailers as of November 1, 2026, with prices from £159 to £332, a £173 spread on the same certified stone. 77 Diamonds lists it at £332. 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.
