About this 1.5ct natural marquise diamond

This 1.5ct natural marquise sits in the one-and-a-half to two carat band, graded M colour (faint-tinted) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6243005789. Listed at 4 retailers as of November 6, 2026, with a relatively tight 8% spread, which is unusual at this carat range and suggests competitive pricing across the listings. 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.
