About this 0.61ct natural cushion diamond

This 0.61ct natural cushion sits in the half to three-quarter carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2566138338. Listed at 4 retailers as of October 29, 2026, with prices from £396 to £486, a £89 spread on the same certified stone. 77 Diamonds lists it at £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.
