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 774683291. Listed at 14 retailers as of November 2, 2026, with prices from $774 to $2,476, a $1,701 spread on the same certified stone. NZ Jewellers lists it at $2,476. 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.
