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 VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI 635476481. Listed at 11 retailers as of November 4, 2026, with prices from HK$2,887 to HK$12,004, a HK$9,117 spread on the same certified stone. NZ Jewellers lists it at HK$12,004. 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.
