Refined, beautifully preserved, and rich in early twentieth-century character, this authentic antique solitaire dates to approximately 1915–1925, during the transition from the final years of the Edwardian era into the emergence of Art Deco design. Crafted in solid 18K gold, the ring combines the delicate ornamentation and hand-finished craftsmanship of the Edwardian period with the balanced symmetry and restrained structure that would soon influence early Art Deco jewelry.
At its center rests a natural antique hand-cut diamond displaying the characteristics commonly associated with an Old Mine Cut, including a high crown, a very small table, a prominent open culet, and subtly irregular, hand-fashioned proportions. The diamond exhibits a gentle warmth that complements the rich tone of the 18K gold mounting, creating the soft and romantic appearance often appreciated in antique diamonds.
More than simply an antique diamond ring, this is a beautifully preserved example of transitional jewelry design. Its airy pierced filigree, crisp hand engraving, and distinctive four-petal floral motifs retain the naturalistic vocabulary of the Edwardian era, while the clean bezel setting and controlled symmetry anticipate the more structured design principles that would soon define Art Deco jewelry.
Authentic antique engagement rings with this combination of original craftsmanship, period character, and preservation are increasingly difficult to find. With its hand-cut diamond, sculptural goldwork, and beautifully preserved decorative details, this ring offers more than a century of jewelry history in a design that remains exceptionally wearable today.

The ring is centered by a natural antique hand-cut diamond exhibiting the visible characteristics commonly associated with an Old Mine Cut. Its high crown, very small table, prominent open culet, and subtly irregular proportions reflect an era when diamonds were fashioned individually by hand rather than cut according to modern standardized measurements.
The diamond displays a gentle warmth rather than an icy white appearance. This subtle warmth is frequently encountered in antique diamonds and pairs beautifully with the rich tone of the 18K gold bezel, contributing to the ring's soft, romantic presentation. No laboratory color or clarity grade has been assigned, and the stone has not been removed from the mounting for evaluation.
Because the diamond is secured within a full bezel setting, a portion of its girdle and overall outline remains concealed beneath the gold. The visible portion measures approximately 3.55 mm across, while the complete bezel measures approximately 5.39 mm. Based on the stone's visible measurements and antique proportions, its weight is conservatively estimated at approximately 0.20 to 0.30 carat. An exact carat weight and definitive cut classification cannot be established without removing the diamond from its original mounting.
Although the bezel limits a complete examination of the stone, the small table, high crown, open culet, and hand-fashioned irregularity strongly support its identification as an antique diamond with Old Mine Cut characteristics. These features create the broad, distinctive flashes of light and individual character that separate early hand-cut diamonds from their modern counterparts.
Crafted during the transition from the Edwardian era into the early years of Art Deco, this ring illustrates the gradual evolution of jewelry design during the early twentieth century. Its delicate pierced filigree and finely engraved ornamentation retain the light, decorative character of Edwardian jewelry, while the symmetrical composition and clean bezel setting introduce a more structured quality associated with the emerging Art Deco aesthetic.
Particularly distinctive are the four-petal flower motifs incorporated into the shoulders. Floral forms, garlands, ribbons, and other naturalistic ornamentation were central to Edwardian design, and the presence of these carefully executed flowers gives the ring a stronger Edwardian influence than would be expected in a mature Art Deco jewel.
The finely pierced gallery creates an airy framework beneath the diamond, while the hand engraving remains unusually crisp for a ring more than a century old. Rather than displaying the bold geometry, stepped forms, or strongly architectural lines of later Art Deco jewelry, the design remains romantic and organic, placing it within the transitional period when Edwardian craftsmanship and emerging modern symmetry coexisted.
Together, the floral shoulders, openwork gallery, crisp engraving, and restrained bezel setting create a ring that does not belong exclusively to one era. Instead, it captures an important moment in jewelry history as the delicacy of Edwardian design gradually gave way to the cleaner and more disciplined forms of Art Deco.
Remarkably well preserved for a ring dating to the early twentieth century, this piece retains its delicate hand-pierced filigree, crisp floral engraving, and beautifully defined period architecture. The decorative details remain unusually sharp, allowing the four-petal flower motifs and surrounding ornamentation to be clearly appreciated.
The natural antique diamond appears secure within its bezel setting, and the 18K gold mounting remains structurally sound. Light surface wear, minor abrasions, and gentle softening are present, consistent with careful use over approximately one hundred years and contributing appropriately to the ring's authentic antique character.
The diamond exhibits the subtle asymmetry, open culet, and gentle warmth expected of an early hand-cut stone. Enlarged photography may reveal internal characteristics and surface details more readily than they are visible during normal viewing.
Taken as a whole, the ring survives in excellent antique condition and remains a beautifully preserved example of Edwardian to early Art Deco transitional craftsmanship.
Photographed under soft-spectrum lighting and high magnification to accurately capture the diamond, hand craftsmanship, and period details of the setting. Enlarged images are intended to reveal gemstone characteristics, surface condition, craftsmanship, and construction details beyond what is typically visible during normal viewing.

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.
