About this 1.3ct natural cushion diamond

This 1.3ct natural cushion sits in the one-and-a-quarter to one-and-a-half carat band, graded J colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI 234623005. Listed at 3 retailers as of November 5, 2026, with prices from £1,839 to £2,486, a £647 spread on the same certified stone. Yorxs lists it at £2,486. 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.
