About this 1.23ct natural marquise diamond

This 1.23ct natural marquise sits in the classic one-carat band, graded K colour (faint-tinted) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI 728564625. Listed at 16 retailers as of November 4, 2026, with a 128% 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.
