This 0.77ct natural princess sits in the just-under-one-carat band, graded K colour (faint-tinted) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1142797308. Listed at 3 retailers as of November 4, 2026, with prices from £806 to £1,229, a £423 spread on the same certified stone. 77 Diamonds lists it at £1,229. 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.
