About this 0.5ct lab-grown marquise diamond

This 0.5ct lab-grown marquise sits in the half to three-quarter carat band, graded I colour (near-colourless) and VS1 clarity (very-slightly-included) and certified by IGI LG541249697 or 541249697. Listed at a single retailer as of November 4, 2026. If it later appears at another store, Carat Hunter will surface the price comparison automatically. 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.
