About this 3ct natural cushion diamond

This 3ct natural cushion sits in the three to five carat band, graded K colour (faint-tinted) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 7558113556. Listed at 6 retailers as of November 4, 2026, with prices from £8,569 to £11,387, a £2,818 spread on the same certified stone. GemTrove lists it at £11,387. 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.
