About this 1.31ct natural cushion diamond

This 1.31ct natural cushion sits in the one-and-a-quarter to one-and-a-half carat band, graded D colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2557427035. Listed at 7 retailers as of October 27, 2026, with prices from £2,031 to £2,835, a £804 spread on the same certified stone. Michael Trio lists it at £2,835. 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.
