About this 0.25ct natural heart diamond

This 0.25ct natural heart sits in the sub-half-carat band, graded D colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6552421546. Listed at 8 retailers as of October 31, 2026, with prices from $339 to $683, a $344 spread on the same certified stone. B2C Jewels lists it at $683. 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.
