This 1.29ct lab-grown heart sits in the one-and-a-quarter to one-and-a-half carat band, graded E colour (colourless) and VVS1 clarity (very-very-slightly-included) and certified by IGI LGG1201805 or G1201805. Listed at 2 retailers as of October 28, 2026, with prices from HK$4,375 to HK$10,253, a HK$5,878 spread on the same certified stone. MOH London lists it at HK$10,253. 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.
