About this 0.81ct natural marquise diamond

This 0.81ct natural marquise sits in the just-under-one-carat band, graded G colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6561587742. Listed at 3 retailers as of October 31, 2026, with a relatively tight 10% 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.
