About this 1.51ct natural cushion diamond

This 1.51ct natural cushion sits in the one-and-a-half to two carat band, graded E 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 2556062592. Listed at 15 retailers as of October 23, 2026, with prices from $5,484 to $11,544, a $6,059 spread on the same certified stone. Wholesale Diamonds Direct lists it at $11,544. 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.
