{"product_id":"edwardian-old-mine-cut-diamond-bypass-ring-18k-platinum","title":"Edwardian Art Nouveau Old Mine Cut Diamond Bypass Ring in 18k Gold \u0026 Platinum, Circa 1910","description":"\u003cp\u003eThere is a remarkable sense of movement in this Edwardian diamond ring. Sweeping platinum curves flow around three principal diamonds, creating an intricate bypass design that feels both graceful and substantial. The composition is complex, yet beautifully balanced, with each element contributing to the whole. It is a ring with undeniable presence, but one that retains the lightness and refinement characteristic of fine Edwardian jewelry.\u003c\/p\u003e\n\u003cp\u003eDating to approximately 1910, the ring reflects the influence of Art Nouveau, a movement that brought flowing lines, organic forms, and a sense of natural movement into jewelry design. Here, those influences are expressed through opposing curves that embrace an old mine-cut center diamond, flanked by two additional diamonds. The platinum-topped gold construction adds depth and dimension, while delicate details soften the architectural complexity.\u003c\/p\u003e\n\u003cp\u003eThe center old mine-cut diamond has a warm, lively character, with the irregular faceting and distinctive open culet associated with early diamond cutting. Its two companion diamonds each have their own personality, while a scattering of roughly fashioned antique accent diamonds follows the surrounding curves. Rather than demanding perfect uniformity, the design brings these different stones together into a cohesive composition.\u003c\/p\u003e\n\u003cp\u003eWhat makes this ring especially appealing is the contrast between its visual delicacy and its substantial construction. There is considerable intricacy in the metalwork, yet nothing feels excessive. The diamonds, flowing lines, and open spaces work together with an effortless sense of proportion. It is precisely this combination of architectural interest, balance, and individuality that earns a ring its place in The TERA Collection.\u003c\/p\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eEra:\u003c\/strong\u003e Edwardian, circa 1905–1915\u003cbr\u003e\u003cstrong\u003eStyle:\u003c\/strong\u003e Art Nouveau-influenced diamond bypass ring\u003cbr\u003e\u003cstrong\u003eMetal:\u003c\/strong\u003e 18ct yellow gold with platinum top\u003cbr\u003e\u003cstrong\u003eRing Size:\u003c\/strong\u003e 7\u003cbr\u003e\u003cstrong\u003eTotal Weight:\u003c\/strong\u003e 3.8 grams\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCenter Stone:\u003c\/strong\u003e Diamond\u003cbr\u003e\u003cstrong\u003eCut:\u003c\/strong\u003e Old mine cut\u003cbr\u003e\u003cstrong\u003eMeasurements:\u003c\/strong\u003e 5.41 × 5.08 mm\u003cbr\u003e\u003cstrong\u003eEstimated Weight:\u003c\/strong\u003e Approximately 0.60 carat, estimated while mounted\u003cbr\u003e\u003cstrong\u003eEstimated Color:\u003c\/strong\u003e L–N range\u003cbr\u003e\u003cstrong\u003eEstimated Clarity:\u003c\/strong\u003e SI range\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSide Stones:\u003c\/strong\u003e Two diamonds, approximately 2.41 mm each\u003cbr\u003e\u003cstrong\u003eCut:\u003c\/strong\u003e Early brilliant-style cuts, exact classification undetermined\u003cbr\u003e\u003cstrong\u003eEstimated Combined Weight:\u003c\/strong\u003e 0.09–0.12 carat\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAccent Stones:\u003c\/strong\u003e Ten irregularly cut antique diamonds, approximately 1.00–1.35 mm each, potentially including rose cuts\u003cbr\u003e\u003cstrong\u003eEstimated Combined Weight:\u003c\/strong\u003e 0.04–0.09 carat\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eEstimated Total Diamond Weight:\u003c\/strong\u003e Approximately 0.75 carat, estimated while mounted\u003cbr\u003e\u003cstrong\u003eHead Width:\u003c\/strong\u003e 15.19 mm\u003cbr\u003e\u003cstrong\u003eHead Height:\u003c\/strong\u003e Approximately 9 mm \u003cbr\u003e\u003cstrong\u003eHeight Above Finger:\u003c\/strong\u003e 5.45 mm\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eRear Shank Width:\u003c\/strong\u003e 0.91 mm\u003cbr\u003e\u003cstrong\u003eRear Shank Depth:\u003c\/strong\u003e 1.64 mm\u003c\/p\u003e\n\u003ch2\u003eThe Stones\u003c\/h2\u003e\n\u003cp\u003eThe central old mine-cut diamond is the natural focal point of the ring. Measuring 5.41 × 5.08 mm, it displays the individuality characteristic of early diamond cutting, including an irregular facet arrangement and a prominent, asymmetrical open culet. Its warm body color and lively reflections give it a character distinctly different from the more uniform appearance of contemporary brilliant-cut diamonds.\u003c\/p\u003e\n\u003cp\u003eThe two flanking diamonds introduce an interesting contrast. Their relatively broad tables, shallow crowns, and individual facet patterns suggest early brilliant-style cutting, although they do not conform neatly to a single established classification. Their appearance complements the older center diamond without attempting to duplicate it.\u003c\/p\u003e\n\u003cp\u003eTen additional antique diamonds are distributed throughout the curved platinum sections. These stones vary in shape and cutting character, with some displaying features suggestive of rose cuts and others appearing more irregularly fashioned. Their purpose is largely decorative, adding texture and subtle points of reflected light along the flowing metalwork.\u003c\/p\u003e\n\u003cp data-pm-slice=\"1 1 []\"\u003e\u003cspan\u003eTogether, the diamonds create a composition in which their individual characteristics become part of the ring's appeal. The principal stones display warm tones and lively reflections, with natural variations in color and clarity that contribute to their distinctive appearance.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch2\u003eThe Setting\u003c\/h2\u003e\n\u003cp\u003eThe ring is constructed in 18ct yellow gold with a platinum-topped decorative framework, a combination closely associated with fine jewelry of the Edwardian period. The platinum follows the contours of the underlying gold structure, allowing the upper surface to retain a bright, refined appearance while the gold provides support and warmth beneath.\u003c\/p\u003e\n\u003cp\u003eThe bypass composition is formed by two opposing curves that sweep around the three principal diamonds. These curved sections carry the smaller accent stones, with fine milgrain defining their edges and decorative engraving adding further detail. The design is not strictly symmetrical in its individual elements, yet the opposing forms create a carefully balanced overall silhouette.\u003c\/p\u003e\n\u003cp\u003eThe central diamond rises above the surrounding composition in a claw setting, while the flanking diamonds occupy circular settings with milgrained borders. Open spaces between the principal settings and the curved decorative sections give the head a sense of transparency and prevent the intricate design from appearing visually heavy.\u003c\/p\u003e\n\u003cp\u003eFrom the side, the elevated settings and open-backed construction reveal the ring's dimensional character. The decorated shoulders transition into a comparatively simple yellow-gold shank, allowing the elaborate head to remain the focus. The relationship between the flowing platinum top, supporting gold framework, and raised diamond settings is central to the ring's architectural appeal.\u003c\/p\u003e\n\u003ch2\u003eThe Styling \u0026amp; Wear\u003c\/h2\u003e\n\u003cp\u003eThis ring has the presence of a statement piece without the visual heaviness often associated with larger designs. Its elongated, flowing silhouette gives it a distinctive look on the hand, while the openwork and refined proportions keep it feeling delicate.\u003c\/p\u003e\n\u003cp\u003eIt would make a beautiful alternative engagement ring for someone drawn to unusual antique designs, particularly those with an appreciation for Art Nouveau and Edwardian craftsmanship. It is equally compelling as a right-hand ring or a meaningful anniversary piece.\u003c\/p\u003e\n\u003cp\u003eThe elevated center setting gives the ring a noticeable profile, so some awareness is appropriate during daily activities. As with any antique diamond ring, the settings should be periodically inspected, and the ring should be removed for activities that could expose it to hard impacts or unnecessary stress.\u003c\/p\u003e\n\u003ch2\u003eA Word on Resizing\u003c\/h2\u003e\n\u003cp\u003eThe ring is currently a size 7. Its plain yellow-gold rear shank may allow for resizing, although the relatively narrow shank and the elaborate platinum-topped head should be considered before any alteration.\u003c\/p\u003e\n\u003cp\u003eResizing should be evaluated by a jeweler experienced in antique jewelry, with particular attention to preserving the original proportions and avoiding stress on the diamond settings. Laser welding may be appropriate depending on the extent of the adjustment.\u003c\/p\u003e\n\u003ch2\u003eNote on Photography\u003c\/h2\u003e\n\u003cp\u003eOur jewelry is photographed at high magnification to show craftsmanship, condition, and detail as clearly as possible. This can make normal signs of age, wear, tool marks, and variations in finish appear more prominent than they are to the unaided eye.
