About this 1.56ct natural cushion diamond

This 1.56ct natural cushion sits in the one-and-a-half to two carat band, graded J colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1433760601. Listed at 21 retailers as of October 31, 2026, with prices from £1,962 to £4,274, a £2,312 spread on the same certified stone. MOH London lists it at £4,274. 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.
