About this 1.24ct natural marquise diamond

This 1.24ct natural marquise sits in the classic one-carat band, graded K 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 2235715142. Listed at 3 retailers as of November 4, 2026, with prices from £2,600 to £4,175, a £1,576 spread on the same certified stone. MOH London lists it at £4,175. 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.
