About this 1ct natural heart diamond

This 1ct natural heart sits in the classic one-carat band, graded L colour (faint-tinted) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI 689598916. Listed at 14 retailers as of November 4, 2026, with a 27% 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.
