This 1.71ct lab-grown emerald sits in the one-and-a-half to two carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG539225479 or 539225479. Listed at 19 retailers as of October 29, 2026, with prices from £237 to £1,187, a £949 spread on the same certified stone. Brilliant Earth lists it at £1,187. 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.
