About this 1.86ct natural princess diamond

This 1.86ct natural princess sits in the one-and-a-half to two carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 5172084593. Listed at 8 retailers as of November 1, 2026, with prices from £11,015 to £16,080, a £5,065 spread on the same certified stone. MOH London lists it at £16,080. 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.
