About this 0.38ct natural heart diamond

This 0.38ct natural heart sits in the sub-half-carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 5566250899. Listed at 2 retailers as of November 1, 2026, with prices from $528 to $717, a $189 spread on the same certified stone. 77 Diamonds lists it at $717. 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.
