About this 1.03ct natural round diamond

This 1.03ct natural round sits in the classic one-carat band, graded K colour (faint-tinted) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI 588340152. Listed at 15 retailers as of November 4, 2026, with a 86% 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.
