About this 2.51ct natural heart diamond

This 2.51ct natural heart sits in the two to three carat band, graded G 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 3525628956. Listed at 15 retailers as of November 1, 2026, with prices from $20,593 to $35,597, a $15,005 spread on the same certified stone. MOH London lists it at $35,597. 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.
