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 IF clarity (flawless or internally-flawless), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1508303528. Listed at 4 retailers as of October 29, 2026, with prices from $3,421 to $20,442, a $17,021 spread on the same certified stone. Do Amore Diamonds lists it at $20,442. 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.
