About this 1.5ct natural oval diamond

This 1.5ct natural oval sits in the one-and-a-half to two carat band, graded M 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 5232595815. Listed at 7 retailers as of November 5, 2026, with prices from £2,161 to £3,375, a £1,214 spread on the same certified stone. Cape Diamonds lists it at £3,375. 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.
