This 0.73ct natural marquise sits in the half to three-quarter carat band, graded I colour (near-colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI 791655544. Listed at 17 retailers as of November 5, 2026, with prices from £660 to £2,092, a £1,431 spread on the same certified stone. NZ Jewellers lists it at £2,092. 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.
