About this 4.1ct lab-grown cushion diamond

This 4.1ct lab-grown cushion sits in the three to five carat band, graded F colour (colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG830661555 or 830661555. Listed at 17 retailers as of October 31, 2026, with prices from HK$5,477 to HK$39,701, a HK$34,225 spread on the same certified stone. Brilliant Earth lists it at HK$39,701. 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.
