About this 3ct natural cushion diamond

This 3ct natural cushion sits in the three to five carat band, graded I colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1545891558. Listed at 12 retailers as of November 4, 2026, with prices from £17,281 to £29,029, a £11,749 spread on the same certified stone. MOH London lists it at £29,029. 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.
