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 H colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG579399936 or 579399936. Listed at 6 retailers as of November 3, 2026, with prices from HK$2,040 to HK$15,693, a HK$13,653 spread on the same certified stone. Michael Trio lists it at HK$15,693. 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.
