About this 3ct lab-grown cushion diamond

This 3ct lab-grown cushion sits in the three to five carat band, graded J colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI LG432012446 or 432012446. Listed at 5 retailers as of November 5, 2026, with prices from HK$14,891 to HK$85,411, a HK$70,520 spread on the same certified stone. MOH London lists it at HK$85,411. 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.
