About this 4.26ct lab-grown princess diamond

This 4.26ct lab-grown princess sits in the three to five carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1537168603. Listed at 13 retailers as of October 29, 2026, with prices from £14,536 to £29,341, a £14,806 spread on the same certified stone. MOH London lists it at £29,341. 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.
