About this 3.09ct lab-grown cushion diamond

This 3.09ct lab-grown cushion sits in the three to five carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2536664012. Listed at 12 retailers as of October 25, 2026, with prices from HK$7,297 to HK$28,388, a HK$21,091 spread on the same certified stone. MOH London lists it at HK$28,388. 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.
