About this 1.73ct lab-grown emerald diamond

This 1.73ct lab-grown emerald sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG600356614 or 600356614. Listed at 17 retailers as of October 28, 2026, with prices from £155 to £1,224, a £1,069 spread on the same certified stone. Brilliant Earth lists it at £1,224. 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.
