About this 1.27ct natural round diamond

This 1.27ct natural round sits in the one-and-a-quarter to one-and-a-half carat band, graded G colour (near-colourless) and I1 clarity (included), with a standard cut grade and certified by IGI 750557210. Listed at 11 retailers as of November 1, 2026, with a 44% 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.
