About this 1.55ct lab-grown cushion diamond

This 1.55ct lab-grown cushion sits in the one-and-a-half to two carat band, graded E colour (colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG519227854 or 519227854. Listed at 16 retailers as of October 28, 2026, with prices from HK$2,009 to HK$9,965, a HK$7,956 spread on the same certified stone. Brilliant Earth lists it at HK$9,965. 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.
