About this 0.6ct natural cushion diamond

This 0.6ct natural cushion sits in the half to three-quarter carat band, graded K colour (faint-tinted) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2227734110. Listed at 5 retailers as of November 4, 2026, with prices from £498 to £614, a £116 spread on the same certified stone. Blue Nile lists it at £614. 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.
