Pair of Art Deco Silver Napkin Rings with Latin Quotations

A pair of two matching silver napkin rings presented in their original blue leatherette or pebbled-skin display case with a cream satin lining. Each ring features a distinctive cut-out openwork design incorporating Latin text. One ring displays the text 'NON SIBI' (Not for oneself) and the other features 'SED OMNIBUS' (But for all), or similar moralistic phrasing common in the early 20th century. The rings are constructed from wide bands of polished metal, likely sterling silver or a high-quality silver plate, with a slightly concave profile. Below the lettering, the design elements include stylized silhouettes of birds or doves, suggesting a theme of peace or charity. The typography is a bold, sans-serif block style characteristic of the Art Deco period, likely dating between 1920 and 1940. There is visible surface oxidation and a dark patina developing in the recessed areas, which is standard for aged silver. The case shows minor wear on the exterior hinges but remains functional with its brass clasp intact. The craftsmanship suggests a custom or boutique manufacturer rather than mass-produced flatware, evidenced by the precision of the fretwork.

Based on my visual examination of this pair of Art Deco napkin rings, I have assessed their value at $350 to $550. These pieces represent a fine example of interwar period silversmithing, bridge the gap between utility and moralistic art. The Latin phrasing 'NON SIBI' and 'SED OMNIBUS'—forming the motto 'Not for oneself, but for all'—is executed in a bold, geometric fretwork characteristic of the Art Deco movement. The presence of the original presentation case significantly enhances the collectibility, as these sets are frequently separated over time. The condition appears consistent with age; the developing patina suggests authentic silver content rather than thin plating, though I observed minor surface abrasions. The market for Deco-period silver remains robust, particularly for items with scholarly or masonic undertones. Comparables for similar fretwork silver pairs range from $200 for silver plate to over $600 for hallmarked sterling by known makers like Mappin & Webb. Factors impacting value include the rarity of the specific Latin motto and the condition of the cream satin lining. Limitations: This appraisal is based solely on digital images. A physical inspection is required to verify the purity of the silver via hallmark stamps (expected on the interior rims) or acid testing. I recommend verifying the manufacturer's mark to determine if this is a boutique commission, which could push the value toward the higher end of the estimate. Precise weighing and check for 'bleeding' on the edges would be necessary to rule out silver-on-copper electroplating.
