This 0.51ct natural marquise sits in the half to three-quarter carat band, graded K colour (faint-tinted) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 5436969478. Listed at 3 retailers as of November 6, 2026, with prices from ₹24,889 to ₹59,570, a ₹34,681 spread on the same certified stone. 77 Diamonds lists it at ₹59,570. 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.
