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 774683291. Listed at 14 retailers as of October 28, 2026, with prices from $515 to $1,733, a $1,218 spread on the same certified stone. NZ Jewellers lists it at $1,733. 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.
