About this 0.3ct natural heart diamond

This 0.3ct 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 1568237312. Listed at 2 retailers as of November 1, 2026, with prices from $242 to $312, a $70 spread on the same certified stone. 77 Diamonds lists it at $312. 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.
