About this 1.54ct natural cushion diamond

This 1.54ct natural cushion sits in the one-and-a-half to two carat band, graded K colour (faint-tinted) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 5556064044. Listed at 2 retailers as of November 1, 2026, with prices from £1,367 to £2,595, a £1,228 spread on the same certified stone. MOH London lists it at £2,595. 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.
