About this 0.29ct natural heart diamond

This 0.29ct natural heart sits in the sub-half-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 6511237787. Listed at 8 retailers as of October 31, 2026, with prices from £171 to £352, a £181 spread on the same certified stone. B2C Jewels lists it at £352. 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.
