About this 0.85ct natural heart diamond

This 0.85ct natural heart sits in the just-under-one-carat band, graded D colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 7311967100. Listed at 13 retailers as of October 30, 2026, with prices from £936 to £3,088, a £2,152 spread on the same certified stone. NZ Jewellers lists it at £3,088. 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.
