About this 0.6ct natural cushion diamond

This 0.6ct natural cushion sits in the half to three-quarter carat band, graded G colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1535440279. Listed at 8 retailers as of October 30, 2026, with prices from £295 to £433, a £138 spread on the same certified stone. Jared lists it at £433. 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.
