About this 0.9ct natural heart diamond

This 0.9ct natural heart sits in the just-under-one-carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 7546079315. Listed at 18 retailers as of October 30, 2026, with prices from $1,385 to $4,588, a $3,203 spread on the same certified stone. NZ Jewellers lists it at $4,588. 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.
