About this 1.53ct natural cushion diamond

This 1.53ct natural cushion sits in the one-and-a-half to two 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 1545982806. Listed at 20 retailers as of October 23, 2026, with prices from £3,576 to £7,540, a £3,964 spread on the same certified stone. Wholesale Diamonds Direct lists it at £7,540. 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.
