This 1.51ct lab-grown heart sits in the one-and-a-half to two carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG840640269 or 840640269. Listed at 14 retailers as of November 1, 2026, with prices from HK$2,016 to HK$10,749, a HK$8,733 spread on the same certified stone. Brilliant Earth lists it at HK$10,749. 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.
