About this 6.3ct lab-grown cushion diamond

This 6.3ct lab-grown cushion sits in the over five carat band, graded D colour (colourless) and VS2 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG729501465 or 729501465. Listed at 8 retailers as of October 29, 2026, with prices from HK$15,705 to HK$99,100, a HK$83,395 spread on the same certified stone. Brilliant Earth lists it at HK$99,100. 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.
