About this 4.87ct lab-grown cushion diamond

This 4.87ct lab-grown cushion sits in the three to five carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 7521400850. Listed at 13 retailers as of November 1, 2026, with prices from £6,504 to £17,983, a £11,479 spread on the same certified stone. Aida Diamonds lists it at £17,983. 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.
