About this 1.57ct natural heart diamond

This 1.57ct natural heart sits in the one-and-a-half to two 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 2546192780. Listed at 8 retailers as of October 31, 2026, with prices from $9,133 to $16,966, a $7,833 spread on the same certified stone. NZ Jewellers lists it at $16,966. 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.
