About this 1.4ct natural radiant diamond

This 1.4ct natural radiant sits in the one-and-a-quarter to one-and-a-half carat band, graded I colour (near-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 5566575712. Listed at 6 retailers as of November 5, 2026, with prices from $5,644 to $8,179, a $2,535 spread on the same certified stone. Cape Diamonds lists it at $8,179. 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.
