About this 0.77ct natural round diamond

This 0.77ct natural round sits in the just-under-one-carat band, graded H colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade and certified by IGI 670401873. Listed at 13 retailers as of October 26, 2026, with a 99% 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.
