About this 0.77ct natural heart diamond

This 0.77ct natural heart sits in the just-under-one-carat band, graded H colour (near-colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 7421478330. Listed at 2 retailers as of October 28, 2026, with prices from £1,182 to £1,703, a £522 spread on the same certified stone. Riddles Jewelry lists it at £1,703. 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.
