This 1.02ct natural marquise sits in the classic one-carat band, graded H colour (near-colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI 821691355. Listed at 2 retailers as of November 2, 2026, with prices from £2,329 to £3,306, a £977 spread on the same certified stone. Yorxs lists it at £3,306. 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.
