This 4.53ct lab-grown heart sits in the three to five carat band, graded E colour (colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG840655012 or 840655012. Listed at 18 retailers as of October 26, 2026, with prices from HK$5,202 to HK$24,930, a HK$19,728 spread on the same certified stone. MOH London lists it at HK$24,930. 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.
