About this 1ct natural marquise diamond

This 1ct natural marquise sits in the classic one-carat band, graded K colour (faint-tinted) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 7556338743. Listed at 11 retailers as of November 5, 2026, with prices from $1,059 to $1,951, a $892 spread on the same certified stone. Wholesale Diamonds Direct lists it at $1,951. 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.
