About this 1.51ct natural cushion diamond

This 1.51ct natural cushion sits in the one-and-a-half to two 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 7416604779. Listed at 12 retailers as of October 29, 2026, with prices from $3,679 to $7,391, a $3,712 spread on the same certified stone. MOH London lists it at $7,391. 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.
