About this 3.55ct lab-grown marquise diamond

This 3.55ct lab-grown marquise sits in the three to five carat band, graded F colour (colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG839691324 or 839691324. Listed at 5 retailers as of October 27, 2026, with a relatively tight 23% 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.
