About this 1ct natural princess diamond

This 1ct natural princess sits in the classic one-carat band, graded J colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1563685435. Listed at 15 retailers as of October 31, 2026, with prices from £968 to £1,742, a £774 spread on the same certified stone. Helzberg Diamonds lists it at £1,742. 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.
