This 0.51ct natural emerald sits in the half to three-quarter carat band, graded I colour (near-colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI 810634426. Listed at 13 retailers as of October 28, 2026, with prices from $500 to $1,684, a $1,184 spread on the same certified stone. NZ Jewellers lists it at $1,684. 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.
