About this 0.51ct natural heart diamond

This 0.51ct natural heart sits in the half to three-quarter 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 2517450428. Listed at 11 retailers as of November 5, 2026, with prices from ₹50,623 to ₹1,72,061, a ₹1,21,439 spread on the same certified stone. NZ Jewellers lists it at ₹1,72,061. 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.
