Refined and distinctly architectural, this authentic Art Deco Old European Cut diamond solitaire embodies the clean geometry and exceptional craftsmanship that defined the early years of the Art Deco era. Crafted in solid 18K white gold, the ring features a beautifully proportioned Old European Cut diamond set in a square four-prong mounting above finely hand-engraved shoulders that retain remarkable crispness more than a century after their creation.
The elegant pierced gallery and meticulously engraved orange blossom motifs reflect the artistry of early twentieth-century jewelers, who combined structural precision with delicate hand finishing. Rather than relying on elaborate ornamentation alone, the ring achieves its beauty through balanced proportions, thoughtful engineering, and refined decorative engraving. Its timeless design remains every bit as wearable today as when it was first crafted, making it equally appealing as an engagement ring or an addition to a fine antique jewelry collection.
Bearing the distinctive CKO maker's mark, attributed to Cummins-Kremer Co. of Los Angeles, California, this authentic Art Deco solitaire represents both exceptional American craftsmanship and the enduring beauty that defines the finest antique jewelry.
The ring is centered on a lively Old European Cut natural diamond that displays the characteristics collectors admire in antique hand-cut stones. Its high crown, small table, and open culet create the broad flashes of light and distinctive facet pattern that distinguish Old European Cuts from their modern counterparts.
Unlike modern brilliant-cut diamonds that emphasize intense scintillation, Old European Cut diamonds produce larger, slower flashes of light with exceptional depth and personality. The diamond remains bright and lively while preserving the handcrafted charm that makes these historic cuts increasingly sought after by collectors and antique jewelry enthusiasts.
Crafted in solid 18K white gold, the ring reflects the restrained elegance of the Art Deco period through clean architectural lines and meticulous hand engraving. The beautifully engraved orange blossom motifs along the shoulders remain remarkably crisp, demonstrating the quality of both the original craftsmanship and the ring's careful preservation.
The elevated square four-prong mounting is supported by an open pierced gallery that allows light to enter beneath the diamond while creating an airy, balanced profile. Every element of the design serves both beauty and function, resulting in a refined solitaire that showcases the exceptional workmanship characteristic of fine American jewelry of the era.
The interior of the shank bears the CKO 18K hallmark, attributed to Cummins-Kremer Co., an American jewelry manufacturer based in Los Angeles, California. Period jewelry trade directories record the company's CKO trademark, linking the mark to a documented early twentieth-century maker.
Jewelry retaining an identifiable maker's mark offers collectors an additional connection to its history, preserving not only the craftsmanship of the piece itself but also the legacy of the workshop that created it.
Very good antique condition consistent with age and careful preservation.
The hand engraving remains exceptionally crisp throughout the shoulders and gallery, while the mounting retains its original architectural form with only minor signs of normal wear expected in an authentic antique ring. The diamond is secure in its setting, and the ring presents beautifully for both everyday wear and special occasions.
Photographed under soft-spectrum lighting and high magnification to accurately capture the brilliance of the Old European Cut diamond, the crisp hand engraving, and the architectural details of the setting.

The Details:
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.
