About this 0.91ct natural heart diamond

This 0.91ct natural heart sits in the just-under-one-carat band, graded H 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 6385126612. Listed at 18 retailers as of November 1, 2026, with prices from $3,058 to $6,547, a $3,489 spread on the same certified stone. MOH London lists it at $6,547. 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.
