About this 1.2ct natural marquise diamond

This 1.2ct natural marquise sits in the classic one-carat band, graded H colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1559555055. Listed at 11 retailers as of November 5, 2026, with prices from $3,379 to $6,751, a $3,372 spread on the same certified stone. Wholesale Diamonds Direct lists it at $6,751. 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.
