About this 1.51ct natural cushion diamond

This 1.51ct natural cushion sits in the one-and-a-half to two carat band, graded F 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 2404444210. Listed at 19 retailers as of November 2, 2026, with prices from $11,053 to $21,518, a $10,465 spread on the same certified stone. MOH London lists it at $21,518. 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.
