About this 0.5ct lab-grown marquise diamond

This 0.5ct lab-grown marquise sits in the half to three-quarter carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included), with a standard cut grade. Listed at 4 retailers as of November 1, 2026, with a relatively tight 24% 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.
