This 1.7ct lab-grown emerald sits in the one-and-a-half to two carat band, graded K colour (faint-tinted) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG451056273 or 451056273. Listed at 10 retailers as of November 5, 2026, with prices from $3,193 to $10,020, a $6,827 spread on the same certified stone. MOH London lists it at $10,020. 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.
