About this 3.03ct natural cushion diamond

This 3.03ct natural cushion sits in the three to five carat band, graded L 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 1453610681. Listed at 9 retailers as of November 4, 2026, with prices from £11,983 to £16,780, a £4,797 spread on the same certified stone. Cape Diamonds lists it at £16,780. 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.
