This 0.64ct natural marquise sits in the half to three-quarter carat band, graded K colour (faint-tinted) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6561384821. Listed at 3 retailers as of November 4, 2026, with prices from ₹54,004 to ₹65,865, a ₹11,861 spread on the same certified stone. 77 Diamonds lists it at ₹65,865. 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.
