This 1.51ct natural cushion sits in the one-and-a-half to two carat band, graded H colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2396444178. Listed at 15 retailers as of October 31, 2026, with prices from £2,324 to £5,057, a £2,732 spread on the same certified stone. MOH London lists it at £5,057. 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.
