About this 4.01ct lab-grown marquise diamond
This 4.01ct lab-grown marquise sits in the three to five carat band, graded I colour (near-colourless) and SI2 clarity (slightly-included) and certified by AGS 104120161007. Listed at 3 retailers as of October 30, 2026, with a relatively tight 3% 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.
