About this 0.52ct natural oval diamond

This 0.52ct natural oval sits in the half to three-quarter carat band, graded K colour (faint-tinted) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI 823659623. Listed at 9 retailers as of October 31, 2026, with a relatively tight 23% spread, which is unusual at this carat range and suggests competitive pricing across the listings. 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.
