About this 0.91ct lab-grown emerald diamond

This 0.91ct lab-grown emerald sits in the just-under-one-carat band, graded I colour (near-colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG407915402 or 407915402. Listed at 11 retailers as of October 31, 2026, with a 422% 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.
