About this 1.09ct natural heart diamond

This 1.09ct natural heart sits in the classic one-carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA. Listed at 4 retailers as of November 4, 2026, with prices from $11,130 to $15,179, a $4,049 spread on the same certified stone. GS Diamonds lists it at $15,179. 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.
