About this 1.51ct natural radiant diamond

This 1.51ct natural radiant sits in the one-and-a-half to two carat band, graded E colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 5526856383. Listed at 12 retailers as of October 29, 2026, with a 91% 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.
