About this 4.02ct natural heart diamond

This 4.02ct natural heart sits in the three to five carat band, graded J colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA. Listed at 3 retailers as of November 5, 2026, with prices from $69,768 to $80,382, a $10,614 spread on the same certified stone. Blue Nile lists it at $80,382. 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.
