About this 4.98ct lab-grown cushion diamond

This 4.98ct lab-grown cushion sits in the three to five carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2517457294. Listed at 12 retailers as of October 31, 2026, with prices from $40,796 to $65,319, a $24,523 spread on the same certified stone. Blue Nile lists it at $65,319. 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.
