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 I colour (near-colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI 780669448. Listed at 8 retailers as of November 5, 2026, with prices from £3,351 to £7,386, a £4,035 spread on the same certified stone. NZ Jewellers lists it at £7,386. 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.
