About this 1.16ct lab-grown marquise diamond

This 1.16ct lab-grown marquise sits in the classic one-carat band, graded E colour (colourless) and SI1 clarity (slightly-included) and certified by IGI LG638496443 or 638496443. Listed at a single retailer as of October 29, 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.
