About this 1.3ct natural marquise diamond

This 1.3ct natural marquise sits in the one-and-a-quarter to one-and-a-half carat band, graded K colour (faint-tinted) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI 780669162. Listed at 5 retailers as of October 31, 2026, with a 84% 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.
