About this 4.51ct lab-grown emerald diamond

This 4.51ct lab-grown emerald sits in the three to five carat band, graded H colour (near-colourless) and VS2 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG594330416 or 594330416. Listed at 17 retailers as of October 26, 2026, with prices from €510 to €2,752, a €2,242 spread on the same certified stone. MOH London lists it at €2,752. 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.
