About this 1.51ct natural heart diamond

This 1.51ct natural heart sits in the one-and-a-half to two carat band, graded G colour (near-colourless) and VVS1 clarity (very-very-slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 5523749686. Listed at 5 retailers as of November 2, 2026, with prices from $15,793 to $28,251, a $12,457 spread on the same certified stone. MOH London lists it at $28,251. 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.
