About this 3.17ct lab-grown cushion diamond

This 3.17ct lab-grown cushion sits in the three to five carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 3465542997. Listed at 18 retailers as of November 6, 2026, with prices from £765 to £5,260, a £4,495 spread on the same certified stone. Do Amore Diamonds lists it at £5,260. 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.
