Twelve natural spiderweb turquoise cabochons are set in two staggered rows across the center face — rounded ovals, elongated forms, and tighter cabochons positioned so the color and web pattern travel naturally from one stone to the next. The ground shifts from soft sky-blue to blue-green, with pale blue passages and green spotting laced by a fine web of golden to red-brown matrix. Each carries its own character; together they read as a carefully chosen suite.
Spiderweb patterning is among the most sought expressions of Turquoise Mountain material, and this cluster shows why — the webbing is fine, consistent, and distributed across stones of genuine visual range rather than selected for uniformity.
A polished heavy-gauge shank rises cleanly beneath the cluster, bright and substantial against the aged complexity of the turquoise. Silver beads punctuate the settings without crowding them, and the bezels are tight and even — the confident, finished presence collectors look for in Mary Ann Spencer's work.
The shank is stamped “M. SPENCER Sterling,” Mary Ann Spencer’s recognized hallmark. An accompanying adhesive label reading “MARY ANN SPENCER TURQ MNTN” identifies both the maker and the stated turquoise source. Turquoise Mountain is a trade name associated with material from the Kingman, Arizona region; in this listing, the stone attribution is supported by the accompanying label and the bracelet’s visual character rather than independent gemological verification. For a vintage or pre-loved piece, that kind of surviving material notation is a meaningful collector detail.
Spencer is a Navajo silversmith based in Gallup, New Mexico. Market and gallery biographies commonly note that she learned silversmithing at age 13 within a working artist community on the Navajo reservation. Her multi-stone cluster cuffs are among her most recognized and collected formats, and her work appears regularly in the Southwest gallery and trading-post market.
Collectors and dealers often associate Spencer’s work with heavy-gauge sterling construction, strong turquoise selection, and clean, confident fabrication. This cuff reflects those qualities through its substantial shank, even bezels, balanced stone placement, and polished finish.
✨ Collector inquiries are welcome. SCJ is open to thoughtful questions, documented observations, and new information that deepens the story of a piece. With permission, selected comments from our Members may be featured in our upcoming Collectors Circle Insights publications.
1. All items in our inventory are pre-loved vintage pieces, and even those described as in “excellent” condition may display very minor imperfections from previous ownership. We make every effort to provide clear photos of any visible irregularity so you can make an informed decision before making your purchase.
Each product description page includes the item's vintage condition classification and a Condition Guide to help you understand the overall condition of the silverwork and stones. Please note:
2. The measurements are given as close approximations, and slight variations may occur.
3. Every photo represents the exact piece you’ll receive, shown in its actual color and condition. While the jewelry itself is never altered, backgrounds are edited to ensure a clean, consistent display.
4. Because screens display colors differently, the exact shade of a piece may vary slightly from one device to another. If you’re looking for a piece to match an item you already own, we suggest viewing the product's photos on multiple devices for the most accurate assessment of color and overtones.
5. At Silver Cactus Jewelry, we are committed to honoring cultural integrity and accurately representing Indigenous art in accordance with the Indian Arts and Crafts Act. We carefully describe each piece in good faith, with complete transparency regarding signed or unsigned status, available provenance, and expert opinion. Attributions to specific artists or tribes are based on expert evaluation but are not guaranteed. Buyers are encouraged to make their own evaluations before purchase.
6. All jewelry is sold as-is. Buyers are responsible for ensuring compatibility with personal sensitivities (e.g., metal allergies).
7. Silver Cactus Jewelry’s liability is limited to the purchase price of the item. No additional warranties are expressed or implied.
Our Approach to Provenance
Every vintage piece carries a story that begins with its maker. Some are clearly signed and dated; others show only a softened hallmark, a sterling/.925 stamp, the place of production or tribal indicator
—and some bear no markings at all.
Evaluation of Unsigned, Unclear, or Unknown Marks
Pre-loved vintage jewelry rarely includes formal documentation. When hallmarks are unclear or missing, we look to the piece itself for insight into provenance and authenticity. Our evaluation may include:
Attribution & Provenance Disclosure
Each piece is described in good faith and with careful attention to accuracy. We provide full transparency regarding whether a piece is signed or unsigned, any known or available provenance, and our informed professional assessment at the time of listing.
Attributions to specific artists, tribes, or mines are based on stylistic analysis, materials, construction techniques, historical context, and available reference material. In cases where hallmarks are unclear, partial, or absent, even recognized experts may reasonably differ in their conclusions. For this reason, all attributions should be understood as informed opinions rather than absolute guarantees.
Native American jewelry is a living tradition, and the learning process never truly ends. Our understanding continues to evolve through ongoing research and the exchange of knowledge with fellow collectors, scholars, artisans, and informed clients. This ongoing dialogue helps preserve accuracy, context, and integrity—ensuring we remain a trusted source of information rather than presenting any single interpretation as final.
Collectors who value this shared approach to learning are invited to join the Collectors Circle, where we exchange newly uncovered information, historical insights, and evolving perspectives on materials, makers, and regional traditions. This collaborative environment allows knowledge to grow responsibly and ensures that both collectors and researchers benefit from continued discovery.
We encourage collectors and enthusiasts to conduct their own independent evaluation prior to purchase. For a detailed explanation of our methodology, limitations, and guarantees, please refer to our Terms of Service.

A Word About Our Insurance Tag
Silver Cactus Jewelry pieces are vintage and one of a kind—often irreplaceable. To honor their history and protect your investment, each item is carefully inspected and secured with an Insurance Tag, ensuring it arrives as represented.
🛡️ Why the Insurance Tag Matters
⚠️ Important: Removing the Insurance Tag terminates the insurance and voids the return policy.
This safeguard preserves the integrity of rare collectibles while reinforcing our commitment to excellence and a client experience that meets or exceeds expectations. For detailed information about our insurance policy, please view our Terms of Service.
Once you are satisfied with your purchase, or after the return period has concluded, you may remove the Insurance Tag. In the unlikely event that any minor adhesive residue remains, a moist pad and jeweler’s cloth are included for gentle cleaning and light polishing.
