About this 1.3ct lab-grown emerald diamond

This 1.3ct lab-grown emerald sits in the one-and-a-quarter to one-and-a-half carat band, graded H colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG593372611 or 593372611. Listed at 3 retailers as of November 5, 2026, with prices from £277 to £795, a £517 spread on the same certified stone. MOH London lists it at £795. 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.
