About this 1.26ct lab-grown cushion diamond

This 1.26ct lab-grown cushion sits in the one-and-a-quarter to one-and-a-half carat band, graded G colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG605313858 or 605313858. Listed at 4 retailers as of November 5, 2026, with prices from HK$4,601 to HK$6,427, a HK$1,826 spread on the same certified stone. Kay Jewelers lists it at HK$6,427. 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.
