About this 1.5ct natural radiant diamond

This 1.5ct natural radiant sits in the one-and-a-half to two carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6551562090. Listed at 21 retailers as of November 4, 2026, with a 85% 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.
