About this 0.26ct natural heart diamond

This 0.26ct natural heart sits in the sub-half-carat band, graded G 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 6542703365. Listed at 8 retailers as of November 2, 2026, with prices from £159 to £337, a £178 spread on the same certified stone. B2C Jewels lists it at £337. 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.
