About this 0.3ct lab-grown emerald diamond

This 0.3ct lab-grown emerald sits in the sub-half-carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG784669171 or 784669171. Listed at 10 retailers as of October 28, 2026, with a 226% spread between the cheapest and most expensive listing. That is exactly the kind of price-discovery gap Carat Hunter was built to surface. 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.
