About this 1.27ct lab-grown cushion diamond

This 1.27ct lab-grown cushion sits in the one-and-a-quarter to one-and-a-half carat band, graded D colour (colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG645412508 or 645412508. Listed at 16 retailers as of October 30, 2026, with prices from HK$2,001 to HK$10,082, a HK$8,082 spread on the same certified stone. Reve Diamonds lists it at HK$10,082. 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.
