About this 1.01ct natural cushion diamond

This 1.01ct natural cushion sits in the classic one-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 2536529489. Listed at 19 retailers as of November 6, 2026, with a 79% 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.
