About this 1.03ct natural cushion diamond

This 1.03ct natural cushion sits in the classic one-carat band, graded D colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1565468179. Listed at 4 retailers as of November 4, 2026, with prices from £1,091 to £1,304, a £213 spread on the same certified stone. Michael Trio lists it at £1,304. 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.
