About this 0.7ct natural heart diamond

This 0.7ct natural heart sits in the half to three-quarter carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1399370690. Listed at 5 retailers as of October 31, 2026, with prices from $902 to $1,379, a $477 spread on the same certified stone. MOH London lists it at $1,379. 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.
