About this 1.5ct lab-grown oval diamond

This 1.5ct lab-grown oval sits in the one-and-a-half to two carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless) and certified by IGI LG761553374 or 761553374. Listed at 27 retailers as of October 31, 2026, with prices from HK$3,711 to HK$24,871, a HK$21,160 spread on the same certified stone. Brilliant Earth lists it at HK$24,871. 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.
