About this 1.3ct natural cushion diamond

This 1.3ct natural cushion sits in the one-and-a-quarter to one-and-a-half carat band, graded J 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 1226205224. Listed at 11 retailers as of November 6, 2026, with a 36% spread between the cheapest and most expensive listing. That is exactly the kind of price-discovery gap Carat Hunter was built to surface. 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.
