This 1.29ct natural marquise sits in the one-and-a-quarter to one-and-a-half 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 6565792499. Listed at 9 retailers as of November 4, 2026, with prices from $3,261 to $5,829, a $2,568 spread on the same certified stone. Wholesale Diamonds Direct lists it at $5,829. 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.
