About this 1.05ct natural marquise diamond

This 1.05ct natural marquise sits in the classic one-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 2235853595. Listed at 5 retailers as of November 2, 2026, with prices from $6,821 to $11,101, a $4,280 spread on the same certified stone. MOH London lists it at $11,101. 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.
