About this 1.03ct natural heart diamond

This 1.03ct natural heart sits in the classic one-carat band, graded H colour (near-colourless) and I1 clarity (included) and certified by GIA 2397527116. Listed at 8 retailers as of October 31, 2026, with a 33% 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.
