About this 1.71ct natural heart diamond

This 1.71ct natural heart 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 5536316597. Listed at 11 retailers as of October 30, 2026, with prices from £5,556 to £11,129, a £5,573 spread on the same certified stone. NZ Jewellers lists it at £11,129. 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.
