Gallery Note:

This Navajo ring is centered on a vivid blue-green turquoise cabochon with warm golden matrix and strong visual movement. The stone’s color range, matrix patterning, and organic depth are consistent with Royston district material, giving the ring a vibrant, stone-forward presence.

The silverwork is intentionally restrained, with a slim bezel that allows the turquoise to command the composition. Chased crescent details along the shoulders introduce subtle movement while keeping the overall design clean, balanced, and wearable.

The adjustable shank carries quiet structural strength, remaining wider where it meets the face and tapering at the center for comfort. Signed R. MAYES and attributed to Navajo silversmith Robert Mayes, this late-1980s ring reflects a period of Southwestern studio jewelry where bold turquoise cabochons and minimal silverwork were often paired for maximum visual impact.

Hallmark & Maker Notes: 

Robert Mayes is referenced in the secondary market as a Navajo silversmith associated with sterling silver jewelry signed R. MAYES or RM. Public biographical information appears limited, so this attribution is based on the hallmark, comparable market references, and the construction of the piece. His known market examples often place emphasis on the stone, pairing turquoise or other cabochons with restrained sterling silverwork.

✨ 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:

  • The guide applies only to the silver and stones.
  • Belt straps, bolo cords, and “throw-in” watches are not covered by the guide, but their condition is described individually on their product pages.
  • Tarnish is not factored into condition ratings, as patina naturally develops with age and does not affect the integrity of the piece.

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:

  • Partial or unknown marks (used as reference points for further research into tribes, families, or regional styles)
  • Historical context
  • Materials (stone, metal, findings, patina)
  • Construction (handwork, joins, settings, finishing)
  • Available reference materials
  • Stylistic details (motifs, proportions, technique clues)

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

  • It guarantees your piece has been inspected prior to shipment.
  • Protects your purchase during transit and for 30 calendar days from the delivery date, so long as the tag remains attached and unaltered.
  • Simplifies returns when the tag is intact and secured, even in the event of damage.

⚠️ 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.
