About this 1.53ct natural cushion diamond

This 1.53ct natural cushion sits in the one-and-a-half to two carat band, graded I 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 1439496635. Listed at 21 retailers as of October 31, 2026, with prices from $3,509 to $7,264, a $3,756 spread on the same certified stone. MOH London lists it at $7,264. 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.
