About this 0.9ct natural princess diamond

This 0.9ct natural princess sits in the just-under-one-carat band, graded K colour (faint-tinted) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 5191895654. Listed at 6 retailers as of November 5, 2026, with prices from £1,128 to £1,549, a £421 spread on the same certified stone. GemTrove lists it at £1,549. 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.
