About this 1.78ct natural princess diamond

This 1.78ct natural princess sits in the one-and-a-half to two carat band, graded J colour (near-colourless) and I1 clarity (included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1232584212. Listed at 8 retailers as of October 27, 2026, with prices from £2,121 to £4,051, a £1,930 spread on the same certified stone. Wholesale Diamonds Direct lists it at £4,051. 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.
