About this 1.51ct natural emerald diamond

This 1.51ct natural emerald sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI 837641308. Listed at 9 retailers as of October 30, 2026, with prices from £2,874 to £6,450, a £3,576 spread on the same certified stone. NZ Jewellers lists it at £6,450. 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.
