This 1.25ct lab-grown heart sits in the one-and-a-quarter to one-and-a-half carat band, graded E colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG831610883 or 831610883. Listed at 6 retailers as of October 28, 2026, with prices from HK$3,429 to HK$9,307, a HK$5,878 spread on the same certified stone. MOH London lists it at HK$9,307. 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.
