About this 1.5ct natural cushion diamond

This 1.5ct natural cushion sits in the one-and-a-half to two carat band, graded E 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 6541578989. Listed at 21 retailers as of October 23, 2026, with prices from $5,643 to $12,022, a $6,379 spread on the same certified stone. Wholesale Diamonds Direct lists it at $12,022. 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.
