About this 0.3ct natural emerald diamond

This 0.3ct natural emerald sits in the sub-half-carat band, graded J colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6512380661. Listed at 15 retailers as of October 29, 2026, with a 132% 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.
