About this 0.81ct natural marquise diamond

This 0.81ct natural marquise sits in the just-under-one-carat band, graded I colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI 604392583. Listed at a single retailer as of October 31, 2026. If it later appears at another store, Carat Hunter will surface the price comparison automatically. 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.
