About this 1.3ct natural round diamond

This 1.3ct natural round sits in the one-and-a-quarter to one-and-a-half carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by GIA 5231484333. Listed at 9 retailers as of November 1, 2026, with prices from $11,283 to $18,247, a $6,964 spread on the same certified stone. MOH London lists it at $18,247. 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.
