About this 1.2ct natural marquise diamond

This 1.2ct natural marquise sits in the classic one-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 5553831752. Listed at 13 retailers as of November 4, 2026, with prices from ₹3,22,427 to ₹5,77,796, a ₹2,55,368 spread on the same certified stone. Helzberg Diamonds lists it at ₹5,77,796. 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.
