About this 1.5ct lab-grown cushion diamond

This 1.5ct lab-grown cushion sits in the one-and-a-half to two carat band, graded G colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI LG530226671 or 530226671. Listed at 7 retailers as of November 1, 2026, with prices from HK$3,868 to HK$10,094, a HK$6,226 spread on the same certified stone. MOH London lists it at HK$10,094. 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.
