About this 0.51ct natural marquise diamond

This 0.51ct natural marquise sits in the half to three-quarter carat band, graded H colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1563140120. Listed at 10 retailers as of October 31, 2026, with prices from ₹43,264 to ₹87,259, a ₹43,996 spread on the same certified stone. Frank Darling lists it at ₹87,259. 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.
