About this 1.21ct natural princess diamond

This 1.21ct natural princess sits in the classic one-carat band, graded H colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 3495143134. Listed at 5 retailers as of November 6, 2026, with prices from £1,677 to £2,784, a £1,107 spread on the same certified stone. 77 Diamonds lists it at £2,784. 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.
