About this 1.5ct natural cushion diamond

This 1.5ct natural cushion sits in the one-and-a-half to two carat band, graded G colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 7558373184. Listed at 20 retailers as of November 2, 2026, with prices from $5,004 to $10,569, a $5,564 spread on the same certified stone. Wholesale Diamonds Direct lists it at $10,569. 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.
