About this 3.51ct lab-grown marquise diamond

This 3.51ct lab-grown marquise sits in the three to five carat band, graded F colour (colourless) and VS2 clarity (very-slightly-included) and certified by IGI LG776688225 or 776688225. Listed at a single retailer as of October 31, 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.
