About this 1.57ct natural cushion diamond

This 1.57ct natural cushion sits in the one-and-a-half to two carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1156743353. Listed at 17 retailers as of October 27, 2026, with prices from £7,606 to £12,881, a £5,275 spread on the same certified stone. MOH London lists it at £12,881. 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.
