About this 4.15ct lab-grown marquise diamond

This 4.15ct lab-grown marquise sits in the three to five carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless) and certified by IGI LGE83421 or E83421. Currently listed at a single retailer. 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.
