About this 1.51ct natural radiant diamond

This 1.51ct natural radiant sits in the one-and-a-half to two carat band, graded J 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 5221559285. Listed at 12 retailers as of November 2, 2026, with prices from $10,525 to $15,598, a $5,072 spread on the same certified stone. Riddles Jewelry lists it at $15,598. 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.
