About this 1.57ct lab-grown cushion diamond

This 1.57ct lab-grown cushion sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade and certified by IGI LG436045066 or 436045066. Listed at 5 retailers as of October 29, 2026, with prices from HK$3,068 to HK$13,332, a HK$10,264 spread on the same certified stone. MOH London lists it at HK$13,332. 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.
