This 1.51ct natural round sits in the one-and-a-half to two carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by GIA 6117790152. Listed at 19 retailers as of November 2, 2026, with prices from $15,244 to $34,333, a $19,089 spread on the same certified stone. Diamond Quarter lists it at $34,333. 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.
