About this 1ct natural marquise diamond

This 1ct natural marquise sits in the classic one-carat band, graded L colour (faint-tinted) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 7766543. Listed at 2 retailers as of November 4, 2026, with a relatively tight 1% 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.
