About this 1.2ct natural marquise diamond

This 1.2ct natural marquise sits in the classic one-carat band, graded G colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 5241080058. Listed at 14 retailers as of November 5, 2026. 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.
