About this 0.51ct natural round diamond

This 0.51ct natural round sits in the half to three-quarter carat band, graded K colour (faint-tinted) and IF clarity (flawless or internally-flawless), with a standard cut grade and certified by GIA 2196270338. Listed at 10 retailers as of November 4, 2026, with prices from $716 to $2,742, a $2,026 spread on the same certified stone. NZ Jewellers lists it at $2,742. 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.
