About this 4.05ct lab-grown cushion diamond

This 4.05ct lab-grown cushion sits in the three to five carat band, graded H colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG840657039 or 840657039. Listed at 17 retailers as of November 2, 2026, with prices from HK$6,126 to HK$41,427, a HK$35,301 spread on the same certified stone. Brilliant Earth lists it at HK$41,427. 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.
