About this 1.29ct lab-grown cushion diamond

This 1.29ct 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 very-good cut grade and certified by IGI LG648417577 or 648417577. Listed at 4 retailers as of November 3, 2026, with prices from HK$5,241 to HK$7,297, a HK$2,056 spread on the same certified stone. Zales lists it at HK$7,297. 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.
