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 very-good cut grade stated by the retailer rather than the lab and certified by GIA 2567647534. Listed at 12 retailers as of October 27, 2026, with prices from $6,144 to $11,090, a $4,946 spread on the same certified stone. Wholesale Diamonds Direct lists it at $11,090. 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.
