About this 2.51ct lab-grown princess diamond

This 2.51ct 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 6512529733. Listed at 3 retailers as of October 31, 2026, with prices from £2,914 to £3,956, a £1,041 spread on the same certified stone. Brilliant Earth lists it at £3,956. 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.
