About this 1.03ct lab-grown cushion diamond

This 1.03ct lab-grown cushion sits in the classic one-carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG840611849 or 840611849. Listed at 12 retailers as of November 5, 2026, with prices from HK$1,097 to HK$10,202, a HK$9,105 spread on the same certified stone. MOH London lists it at HK$10,202. 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.
