This 1.28ct lab-grown cushion sits in the one-and-a-quarter to one-and-a-half carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG582349421 or 582349421. Listed at 9 retailers as of November 6, 2026, with prices from HK$1,944 to HK$16,694, a HK$14,750 spread on the same certified stone. Do Amore Diamonds lists it at HK$16,694. 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.
