About this 1.73ct natural emerald diamond

This 1.73ct natural emerald sits in the one-and-a-half to two carat band, graded K colour (faint-tinted) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI 720559392. Listed at 11 retailers as of November 5, 2026, with prices from £2,239 to £4,515, a £2,277 spread on the same certified stone. NZ Jewellers lists it at £4,515. 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.
