About this 0.55ct lab-grown emerald diamond

This 0.55ct lab-grown emerald sits in the half to three-quarter carat band, graded E colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade and certified by GCAL 312450087. Listed at 8 retailers as of November 4, 2026, with a 556% 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.
