About this 1ct lab-grown emerald diamond

This 1ct lab-grown emerald sits in the classic one-carat band, graded J colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG380970969 or 380970969. Listed at 8 retailers as of October 28, 2026, with prices from HK$4,551 to HK$23,113, a HK$18,563 spread on the same certified stone. NZ Jewellers lists it at HK$23,113. 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.
