About this 1.51ct natural cushion diamond

This 1.51ct natural cushion sits in the one-and-a-half to two carat band, graded L 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 5546760264. Listed at 5 retailers as of November 5, 2026, with prices from £1,715 to £2,127, a £413 spread on the same certified stone. Yorxs lists it at £2,127. 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.
