About this 0.34ct natural heart diamond

This 0.34ct natural heart sits in the sub-half-carat band, graded H 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 1568781006. Listed at 5 retailers as of November 2, 2026, with prices from £246 to £342, a £96 spread on the same certified stone. 77 Diamonds lists it at £342. 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.
