About this 1.3ct natural marquise diamond

This 1.3ct natural marquise sits in the one-and-a-quarter to one-and-a-half carat band, graded D colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 5556626018. Listed at 5 retailers as of October 31, 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.
