About this 0.9ct natural emerald diamond

This 0.9ct natural emerald sits in the just-under-one-carat band, graded H colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI 520279594. Listed at 13 retailers as of October 28, 2026, with prices from $1,644 to $4,284, a $2,639 spread on the same certified stone. NZ Jewellers lists it at $4,284. 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.
