About this 0.9ct natural heart diamond

This 0.9ct natural heart sits in the just-under-one-carat band, graded I colour (near-colourless) and I1 clarity (included), with a standard cut grade and certified by IGI 487181632. Listed at 8 retailers as of October 27, 2026, with a 43% 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.
