About this 1.2ct natural cushion diamond

This 1.2ct natural cushion sits in the classic one-carat band, graded D colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1555540155. Listed at 15 retailers as of October 28, 2026, with prices from $4,451 to $10,985, a $6,534 spread on the same certified stone. Queensmith lists it at $10,985. 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.
