About this 1ct natural cushion diamond

This 1ct natural cushion sits in the classic one-carat band, graded F colour (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 2546510316. Listed at 16 retailers as of October 30, 2026, with prices from £1,418 to £2,619, a £1,202 spread on the same certified stone. Helzberg Diamonds lists it at £2,619. 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.
