About this 0.4ct natural heart diamond

This 0.4ct natural heart sits in the sub-half-carat band, graded I 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 1567241139. Listed at 2 retailers as of October 31, 2026, with prices from $466 to $595, a $129 spread on the same certified stone. 77 Diamonds lists it at $595. 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.
