About this 1.2ct lab-grown marquise diamond

This 1.2ct lab-grown marquise sits in the classic one-carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included) and certified by IGI LG649456973 or 649456973. Listed at a single retailer as of November 2, 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.
