This 0.51ct natural marquise sits in the half to three-quarter carat band, graded I colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2556632974. Listed at 4 retailers as of November 6, 2026, with prices from ₹43,391 to ₹53,965, a ₹10,574 spread on the same certified stone. 77 Diamonds lists it at ₹53,965. 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.
