About this 3.1ct lab-grown marquise diamond

This 3.1ct lab-grown marquise sits in the three to five carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless) and certified by IGI LG768631785 or 768631785. Listed at a single retailer as of November 1, 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.
