About this 0.7ct natural heart diamond

This 0.7ct natural heart sits in the half to three-quarter carat band, graded J colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2498096602. Listed at 10 retailers as of November 2, 2026, with prices from £409 to £1,325, a £916 spread on the same certified stone. Diamond Exchange Canada lists it at £1,325. 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.
