About this 3.12ct natural cushion diamond

This 3.12ct natural cushion sits in the three to five carat band, graded J colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2151830741. Listed at 20 retailers as of November 4, 2026, with prices from £21,396 to £37,174, a £15,778 spread on the same certified stone. MOH London lists it at £37,174. 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.
