About this 0.9ct natural heart diamond

This 0.9ct natural heart sits in the just-under-one-carat band, graded E 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 5526426015. Listed at 21 retailers as of October 27, 2026, with prices from $1,500 to $4,064, a $2,565 spread on the same certified stone. NZ Jewellers lists it at $4,064. 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.
