This 1.54ct lab-grown cushion sits in the one-and-a-half to two carat band, graded J colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG569301189 or 569301189. Listed at 5 retailers as of October 26, 2026, with prices from £284 to £796, a £512 spread on the same certified stone. MOH London lists it at £796. 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.
