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 H colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by GIA 6422450481. Listed at 21 retailers as of November 5, 2026, with prices from $4,232 to $12,200, a $7,968 spread on the same certified stone. Diamond Quarter lists it at $12,200. 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.
