About this 2.78ct lab-grown princess diamond

This 2.78ct lab-grown princess sits in the two to three carat band, graded D 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 7506850470. Listed at 24 retailers as of October 26, 2026, with prices from $3,240 to $15,170, a $11,930 spread on the same certified stone. Zales lists it at $15,170. 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.
