This 1.25ct natural marquise sits in the one-and-a-quarter to one-and-a-half carat band, graded J colour (near-colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI 768624230. Listed at 3 retailers as of November 6, 2026, with prices from $4,085 to $7,205, a $3,120 spread on the same certified stone. MOH London lists it at $7,205. 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.
