About this 1.7ct natural radiant diamond

This 1.7ct natural radiant sits in the one-and-a-half to two carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 12555259. Listed at 2 retailers as of October 31, 2026, with prices from ₹11,09,336 to ₹13,46,487, a ₹2,37,151 spread on the same certified stone. 77 Diamonds lists it at ₹13,46,487. 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.
