About this 0.73ct lab-grown emerald diamond

This 0.73ct lab-grown emerald sits in the half to three-quarter carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG414059531 or 414059531. Listed at 11 retailers as of October 29, 2026, with prices from $781 to $3,810, a $3,030 spread on the same certified stone. MOH London lists it at $3,810. 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.
