About this 3.01ct natural marquise diamond

This 3.01ct natural marquise sits in the three to five carat band, graded K 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 6555983815. Listed at 12 retailers as of October 30, 2026, with a relatively tight 18% 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.
