999 Fine Silver vs 925 Sterling Silver

Silver purity is useful information, but it is only one part of choosing and caring for a piece of jewelry. This guide explains the terms used on Asteria et Lune product pages and the product-specific details to check before you order.

What “999 fine silver” means

“999” identifies silver with a stated purity of 99.9%. “925 sterling silver” identifies an alloy containing 92.5% silver, with the remaining percentage made up of other metals. These figures describe metal content. They do not, by themselves, describe the exact form, surface finish, fit, weight, construction or care needs of a particular design.

Material term Stated silver content What to confirm on the product page
999 fine silver 99.9% silver Form, surface finish, dimensions, fit, adjustability and any additional materials
925 sterling silver 92.5% silver Form, surface finish, dimensions, fit, adjustability and any additional materials

What purity does—and does not—tell you

Purity is a material fact, not a complete description of a piece. A cuff, a fixed bangle, a fine chain bracelet and an open ring place different demands on construction and fit. Likewise, a smooth surface, chased detail, filigree or a piece with additional materials may call for different handling. Use the exact information provided for the individual design rather than relying on a general material term alone.

How to read an Asteria et Lune product page

For the clearest picture of a piece, read the confirmed details together:

  • Silver purity: shown only where confirmed for that product.
  • Product form: such as cuff, bangle, bracelet, open ring or necklace.
  • Surface finish: the handworked character or texture identified for the design.
  • Dimensions and fit notes: the measurement system used for that form.
  • Adjustable: whether the design is intended to offer adjustment.
  • Other materials: any additional material named for that individual piece.

Why product-specific information matters

Asteria et Lune works with material and craft facts product by product. A page may identify 999 fine silver or 925 sterling silver where that purity has been verified. We do not use “sterling silver” as a substitute for a confirmed 999 fine silver description, and we do not apply one craft term mechanically across the collection.

Before you order

  1. Confirm the stated purity on the exact product page.
  2. Check the form, dimensions and fit notes rather than comparing only a title or photograph.
  3. For cuffs, bangles and rings, read the relevant sizing guide before ordering.
  4. Follow the product page first if it provides a care instruction specific to its finish or materials.
