This 1.2ct lab-grown heart sits in the classic one-carat band, graded E colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG831679846 or 831679846. Listed at 14 retailers as of October 30, 2026, with prices from HK$1,616 to HK$8,238, a HK$6,622 spread on the same certified stone. Brilliant Earth lists it at HK$8,238. 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.
