About this 1.71ct lab-grown emerald diamond

This 1.71ct lab-grown emerald sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and VVS2 clarity (very-very-slightly-included), with a standard cut grade and certified by IGI LG612329209 or 612329209. Listed at 6 retailers as of November 1, 2026, with prices from £320 to £935, a £615 spread on the same certified stone. MOH London lists it at £935. 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.
