About this 1.45ct lab-grown cushion diamond

This 1.45ct lab-grown cushion sits in the one-and-a-quarter to one-and-a-half carat band, graded E colour (colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG677563845 or 677563845. Listed at 14 retailers as of October 28, 2026, with prices from HK$2,244 to HK$17,808, a HK$15,565 spread on the same certified stone. Do Amore Diamonds lists it at HK$17,808. 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.
