About this 0.51ct natural emerald diamond

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 726555001. Listed at 17 retailers as of October 27, 2026, with prices from $435 to $1,771, a $1,336 spread on the same certified stone. NZ Jewellers lists it at $1,771. 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.
