About this 0.3ct lab-grown emerald diamond

This 0.3ct lab-grown emerald sits in the sub-half-carat band, graded H colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG538270706 or 538270706. Listed at 5 retailers as of October 28, 2026, with prices from $231 to $1,046, a $815 spread on the same certified stone. MOH London lists it at $1,046. 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.
