About this 1.5ct natural cushion diamond

This 1.5ct natural cushion sits in the one-and-a-half to two carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2436909050. Listed at 27 retailers as of November 1, 2026, with prices from $12,366 to $22,732, a $10,366 spread on the same certified stone. MOH London lists it at $22,732. 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.
