About this 1.05ct natural round diamond

This 1.05ct natural round sits in the classic one-carat band, graded H colour (near-colourless) and I1 clarity (included), with a very-good cut grade and certified by GIA. Listed at 17 retailers as of October 30, 2026, with a 169% 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.
