About this 0.21ct natural heart diamond

This 0.21ct natural heart sits in the sub-half-carat band, graded H colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6551181311. Listed at 8 retailers as of October 31, 2026, with prices from £163 to £340, a £177 spread on the same certified stone. B2C Jewels lists it at £340. 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.
