About the 0.47ct Round Brilliant Loose Diamond GIA J SI1

This is a single loose round brilliant diamond of 0.47 carat, graded J for color and SI1 for clarity by the GIA, with report number 2221881945. The GIA report is the main selling point: it independently confirms the grade, so you are not relying on a seller's opinion. At $749.99 at Wilson Brothers Jewelry as of November 5, 2026, it is the only new price listed, so there is no recent range to compare against; judge it against other GIA-certified stones of the same weight and grade.

Cons

More deals like this

  • Early Black Friday Jewelry Deals 2026
  • 0.47 carat is just under the half-carat mark

  • SI1 means inclusions are visible under magnification and occasionally to the eye
  • Only one new price listed, so there is no price history to lean on

    • Questions and answers

    Is a J SI1 diamond a good buy?
    Yes, if you want a certified stone at a lower price. J color and SI1 clarity are the usual compromise grades: the tint is mild and the inclusions are small at this size. Check the GIA report for the clarity plot and any fluorescence before buying.
    Is 0.47 carat big enough for a ring?
    It reads as a small but noticeable center stone, roughly 5 mm across in a round brilliant. It suits a solitaire or a ring with side stones. If you want a stone that looks closer to half a carat, expect to pay more for 0.50 ct.
    Can I verify the GIA report?
    Yes. Look up report number 2221881945 in the GIA Report Check tool on GIA's website. The report should match the carat weight, color, clarity and cut grades listed here.
    What does SI1 clarity mean?
    Slightly Included 1: inclusions are easy to see under 10x magnification but are minor. At 0.47 ct most SI1 stones look clean to the naked eye, but confirm on the report and in photos.
    Is this a good price?
    At $749.99 at Wilson Brothers Jewelry as of November 5, 2026, it is about $1,600 per carat, which is in line for a GIA-certified J SI1 round of this size. Compare against other certified 0.45 to 0.50 ct stones before deciding.
    What comes with the diamond?
    You get the loose stone and the GIA report tied to report number 2221881945. A setting, ring and appraisal are not included unless the seller says so.
