Antique 14K Gold Bloodstone Intaglio Signet Ring, “Non Invita Minerva”
A Classical Minerva Owl Seal Symbolizing Wisdom and Inspired Genius
An exceptional antique signet ring crafted in substantial 14K yellow gold and set with a cushion-shaped panel of richly colored bloodstone.
The dark green bloodstone is naturally accented by distinctive red inclusions and intricately carved in intaglio with a standing owl beneath a flowing ribbon bearing the Latin inscription “NON INVITA MINERVA.” Both the image and lettering are engraved in reverse, indicating that the ring was created as a functional seal that would produce a correctly oriented impression in wax.
The owl is the traditional companion and attribute of Minerva, the Roman goddess associated with wisdom, learning, craftsmanship and inspired ability. The Latin expression invita Minerva describes acting without inspiration or against one’s natural aptitude. Preceded by non, the motto expresses the opposite idea: proceeding with Minerva’s favor and in accordance with one’s intellectual and creative gifts.
The substantial 14K gold mounting has broad, softly rounded shoulders and a strong architectural profile, giving the ring a commanding presence on the hand. Its combination of classical symbolism, Latin inscription and functional seal engraving makes it an especially compelling jewel for collectors of antique signet rings, carved hardstones and historically meaningful jewelry.

Collector’s Note
The carving is more than a generic heraldic bird: the owl and Latin motto form a unified classical emblem devoted to Minerva, wisdom and inspired talent. The phrase Non invita Minerva has also appeared in historical heraldic motto records, including in association with the Scott surname. However, without documented provenance or a matching family armorial record, the ring should not be attributed to a particular family or individual.

How do I know a piece is authentic, and can I trust DSF?
Buying fine jewelry online takes trust, especially at this level. DSF Antique Jewelry is a New York–based dealer with over 50 years of fine jewelry expertise. Every piece is examined for authenticity and condition before it is listed — we assess hallmarks, maker's marks, metal content, gemstones, and construction consistent with the stated period or designer. For signed pieces such as Cartier, Buccellati, or Van Cleef & Arpels, we verify maker's marks and signatures. We're glad to send additional photographs of any hallmark, or speak with you directly, before you decide.
Why does antique gold look different, and is surface wear normal?
Antique pieces were often made in gold standards less common today, such as 15ct (used in Britain only between 1854 and 1932), 9ct, or higher-karat continental gold, which give a warmer tone than typical modern 14k. Light surface wear, softened edges, and a gentle patina are normal and expected on antique jewelry — they reflect the age and authenticity of the piece, not flaws. We describe the true condition of every item honestly in its listing.
What do the hallmarks and maker's marks mean?
Hallmarks are small stamped marks that identify the metal standard, and often the maker, assay office, and date. They are one of the best tools for authenticating antique jewelry. We identify and explain the marks we find on each piece in its description, and we're happy to send close-up photographs of any hallmark on request so you can see exactly what you're buying.
Can pieces be resized or adjusted?
It depends on the piece. Many antique rings can be resized, but bands with all-around engraving, thin shanks, or gemstones near the base may be limited in how far they can safely go, and some pieces are best left as-is to preserve their integrity. We list each item's measurements as they currently are. If you're unsure whether something can be safely adjusted, contact us before buying and we'll give you an honest assessment for that specific piece.
How should I care for and store fine jewelry?
Clean gently with a soft cloth, avoid harsh chemicals, ultrasonic cleaners, and chlorine, and store pieces separately so they don't scratch one another. Remove rings and bracelets for heavy manual tasks. Antique gold is softer than modern alloys, so period pieces are best enjoyed with normal care. Treated well, fine antique jewelry lasts for generations — many of our pieces are already a century or more old and still beautiful.
