About this 1.23ct natural marquise diamond

This 1.23ct natural marquise sits in the classic one-carat band, graded E colour (colourless) and SI2 clarity (slightly-included) and certified by GIA 1568376756. Listed at a single retailer as of November 3, 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.
