A true survivor of the Art Deco era, this ring carries the unmistakable presence of a hand-forged piece, not mass-produced, by the well-known Newark jewelry manufacturer Bishop & Bishop—a rare example of craftsmanship from a time when jewelry was built with intention, not efficiency.  There’s an immediate sense of substance in hand—dense, solid, and quietly powerful—reflecting the superior materials and methods of the 1920s.

At its core is a vivid sapphire, elevated within a striking architectural “bridge” gallery. The design rises with purpose, echoing the bold geometry of the era’s skyline, as if the stone itself is suspended at the center of a miniature structure. Every angle reveals thoughtful hand-finishing—details that simply don’t exist in modern cast pieces.

This isn’t just vintage. It’s a piece of history you can feel the moment you pick it up.

DETAILS

This is an authentic Art Deco survivor featuring a hand-finished "Bridge" filigree gallery.

  • The Stone: The sapphire shows natural internal inclusions (silk and feathers) under magnification, confirming earth-mined origin. The color remains a strong blue in all lighting profiles. At high magnification, the stone could be unheated, but this is not confirmed.
  • The Metal: Solid 10% Iridium Platinum with era-correct surface patina. The interior shank contains an original manufacturing die-strike irregularity from the forging process.
  • The Hallmarks: Stamped "10% IRID PLAT". Maker's marks are present but show significant wear and are currently illegible.

CONDITION & AUTHENTICITY

  • This is an authentic antique piece, approximately 100 years old. It has been preserved in its original state, showcasing an honest patina and the unique character of hand-fabricated jewelry.
  • Note on Authenticity: The interior shank shows a unique period-correct miss-stamp from the original jeweler’s punch. This double-strike is a common characteristic of hand-finished early 20th-century jewelry and serves as a "fingerprint" of its authentic, manual creation.
  • The head shows evidence of a historic repair, likely completed using a different metal alloy. The repair is only visible under certain lighting conditions and close examination, and does not impact the ring's structural integrity or wearability.
  • The shank shows some thinning.

Condition and Expectations

Many pieces in the TERA Collection are a century old or more. They have been worn, cherished, gifted, celebrated, and carried through generations before arriving here. Gentle wear, subtle signs of age, and the occasional evidence of historic stewardship should be expected and are considered part of the character that makes antique jewelry impossible to replicate.

Our photography is intentionally detailed and often captured at extreme magnification. In many cases, the images reveal details, textures, and tiny imperfections that are difficult or impossible to see during normal wear. This approach reflects our commitment to documenting each piece as completely as possible, ensuring that its condition, craftsmanship, and character are faithfully represented.

The result is simple: when your piece arrives, there should be no surprises. What you see is an authentic record of a jewel's present condition, preserving both its beauty and the story written into it over time.

If a condition issue exceeds what would normally be expected from a piece of its age, it will always be specifically disclosed within the listing.

Because every collector values different details, we are always happy to provide additional photographs, videos, measurements, or condition documentation whenever possible. If there is a particular aspect of a piece you would like to examine more closely, please don't hesitate to ask.

Our hope is simple: that the piece you receive is exactly the piece you expected to receive. We would always rather answer one more question than leave a doubt unanswered.
