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 J colour (near-colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG407985738 or 407985738. Listed at 3 retailers as of November 1, 2026, with prices from HK$3,099 to HK$8,190, a HK$5,091 spread on the same certified stone. MOH London lists it at HK$8,190. 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.
