About this 0.75ct natural heart diamond

This 0.75ct 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 2183817627. Listed at 4 retailers as of October 29, 2026, with prices from $2,136 to $3,757, a $1,621 spread on the same certified stone. MOH London lists it at $3,757. 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.
