This is a true Belais original—an early white gold ring from the dawn of the Art Deco era, when design began to move toward structure, balance, and precision. The piece is defined by its composed, architectural presence, centered around an Old European cut diamond set within a clean octagonal frame.

There’s a quiet confidence to this ring. The diamond draws you in rather than overwhelms, its broad, hand-cut facets producing a softer, more dimensional light. It’s not just sparkle—it’s depth—subtle, layered, and constantly shifting as it moves.

The architecture is where this ring separates itself. Intricate hand-cut filigree flows through the shoulders and gallery, lightening the structure while adding detail at every angle. This is craftsmanship that simply doesn’t exist in modern cast pieces.

The faint “B” preceding the clearly struck LAIS 18K hallmark confirms this as a genuine Belais Brothers ring—an original example of early American white gold at a time when the material itself was still an innovation.

Details

This is an authentic Belais Brothers ring, showcasing the refined craftsmanship and early white gold innovation the maker was known for.

  • The Diamond: The center stone exhibits the defining characteristics of an Old European cut, including a visible open culet, higher crown, and broad facet pattern typical of hand-cut diamonds from the early 20th century. The light return is softer and more dimensional than modern cuts, offering depth rather than sharp brilliance.
  • The Setting: The diamond is framed within a structured octagonal bezel, giving the ring a balanced architectural presence. This design reflects the transition from the flowing forms of the Edwardian era into the more geometric influence of early Art Deco.
  • The Shoulders: The shoulder design features an elongated, organic pattern that can be interpreted as a subtle wheat motif—symbolically associated with prosperity and abundance. This type of naturalistic detailing is occasionally seen in transitional pieces from the late Edwardian to early Art Deco period.
  • The Craftsmanship: Intricate hand-cut filigree runs throughout the gallery and shoulders, allowing light to pass through the setting while maintaining strength. Slight irregularities in the piercings are consistent with hand fabrication and are a hallmark of authentic antique construction.
  • The Hallmark: The stamp “LAIS 18K,” along with a faint preceding “B,” is consistent with Belais Brothers markings. This serves as a key indicator of authenticity and adds to the ring’s collector appeal.

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.
