About this 1.09ct natural cushion diamond

This 1.09ct natural cushion sits in the classic one-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 7568248235. Listed at 6 retailers as of November 5, 2026, with prices from ₹1,00,964 to ₹1,23,223, a ₹22,259 spread on the same certified stone. Blue Nile lists it at ₹1,23,223. 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.
