About this 1.23ct lab-grown emerald diamond

This 1.23ct lab-grown emerald sits in the classic one-carat band, graded H colour (near-colourless) and VS1 clarity (very-slightly-included) and certified by IGI LG611371875 or 611371875. 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.
