About this 0.7ct natural heart diamond

This 0.7ct natural heart sits in the half to three-quarter carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 7551299241. Listed at 16 retailers as of October 27, 2026, with prices from £487 to £1,659, a £1,171 spread on the same certified stone. NZ Jewellers lists it at £1,659. 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.
