About this 1.42ct lab-grown heart diamond

This 1.42ct lab-grown heart sits in the one-and-a-quarter to one-and-a-half carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG852642865 or 852642865. Listed at 6 retailers as of October 31, 2026, with prices from HK$2,628 to HK$6,660, a HK$4,032 spread on the same certified stone. Taylor and Hart lists it at HK$6,660. 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.
