About this 0.31ct natural marquise diamond

This 0.31ct natural marquise sits in the sub-half-carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 7531899976. Listed at 4 retailers as of November 1, 2026, with prices from ₹20,690 to ₹30,402, a ₹9,711 spread on the same certified stone. 77 Diamonds lists it at ₹30,402. 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.
