The Aztec Calendar Pendant, also known as the Piedra del Sol or Sun Stone, is one of the most iconic and visually arresting symbols in Mesoamerican art. When you’re shopping for one, the challenge isn’t finding a pendant—it’s finding one that captures the intricate, layered geometry of the original Mexica sculpture without looking like a tourist trinket. The difference between a sharp, deeply engraved piece of jewelry and a blurry, lightweight casting comes down to the metal purity, the engraving depth, and the diameter of the round.
I’m Min — the co-founder and writer behind Gadgets Feed. I’ve spent hundreds of hours cross-referencing metal purity marks, comparing engraving fineness across brands, and analyzing customer feedback on wear durability to determine which pendants can survive daily use versus those that belong in a display case.
This guide cuts through the marketing to find the best aztec calendar pendant for your specific needs, whether you value heirloom-grade gold or a sterling silver piece that won’t tarnish after a month.
How To Choose The Best Aztec Calendar Pendant
Choosing the right Aztec Calendar Pendant comes down to three core factors: the metal and its purity, the diameter of the round, and the depth and precision of the engraving. A pendant that looks crisp in a product photo may appear blurry at a 1-inch diameter, and a cheap zinc alloy piece will tarnish within weeks. Here’s what to watch for.
Metal Purity and Wear Durability
The single biggest failure point in this category is low-quality base metal that fades or turns skin green. .925 sterling silver offers a strong balance of brightness and durability—it shines well with a polish cloth and can be worn daily. For gold, 10K or 14K solid gold is far more resistant to scratching and fading than gold-plated sterling, which can wear down to the silver beneath after a few months of regular contact with skin oils and moisture.
Diameter and Engraving Detail
The Aztec Calendar is composed of concentric rings of glyphs, symbols, and the central face of Tonatiuh. If the pendant is too small—under 1 inch—these details become muddled and hard to read. A 1.2-inch or 1.5-inch diameter allows the engraver to preserve the sharp lines of the four previous suns and the outer fire serpent ring. Look for pendants where the customer images show a clear contrast between the recessed engraving and the raised background.
Pendant Form vs. Coin Round
Some Aztec Calendar pendants are repurposed .999 fine silver coin rounds with a bail soldered on. These are thicker and heavier, with a mirrored finish on the reverse. Proper pendants, by contrast, are often thinner with a bail integrated into the casting and a blank or lightly textured reverse. Coin rounds hold bullion value better, while pendants are more comfortable to wear under a shirt due to their lower profile.

In‑Depth Reviews
1. Claddagh Gold .925 Sterling Silver Round Aztec Mayan Calendar Charm Pendant
Claddagh Gold delivers a .925 sterling silver pendant that buyers consistently describe as having decent weight and a finish that looks far more expensive than its price point. The large option measures roughly the diameter of a silver dollar, giving the engraving enough real estate to render the central Tonatiuh face and the outer fire serpent ring with visible clarity. Multiple verified buyers specifically note that it pairs beautifully with a sterling silver rope chain, where the bright white metal creates strong contrast against the recessed details.
The reverse side is intentionally blank—expected for a sundial-style pendant—but a few buyers mentioned they wished it had any design at all. Despite that, the general consensus is overwhelming satisfaction, with the pendant holding its polish well through regular wear. The mid-size option offers a good middle ground for those who want a noticeable piece without the heft of the largest version.
This pendant represents the sweet spot in the category: genuine sterling silver with no plated layer to wear off, a diameter large enough to preserve glyph detail, and a weight that feels substantial without being uncomfortable. It’s the most versatile pick for anyone wanting a daily-wear Aztec Calendar pendant that won’t tarnish or fade.
Why it’s great
- Genuine .925 sterling with solid weight and a premium polished finish
- Multiple size options (small, mid, large) to suit different necklines and preferences
- Buyers consistently report it looks much more expensive than it actually is
Good to know
- Reverse side is completely blank with no engraving or texture
- Sterling silver will tarnish over time without occasional polishing
2. Gold Round 1″/1.2″/1.5″ Aztec Mayan Calendar Medallion Pendant (10K or 14K Gold)
Claddagh Gold’s solid gold offering is the heirloom-grade choice in this category, available in 10K or 14K yellow, rose, or white gold at 1-inch, 1.2-inch, and 1.5-inch diameters. This is not a plated piece—the gold runs through the entire casting, meaning there is no base metal to expose if the surface gets scratched. Verified buyers who have worn it daily for over seven months report that it looks as good as the day they bought it, even with regular exposure to shower moisture and pool water.
The 1.2-inch version offers the best balance of visual presence and comfortable weight, though some buyers noted it was lighter than they expected based on the size. The backside is plain with no engraving, which is consistent across most pendant-style castings in this category. The craftsmanship on the front is described as having a superb cut with crisp detail on the ring glyphs, and the piece arrives with an authenticity certificate for the gold purity.
This is the right choice for someone who wants a permanent piece of jewelry that can be worn every day without worrying about plating wear or metal allergies. The 14K option offers a richer gold tone and slightly higher scratch resistance than 10K, while the 10K option is more abrasion-resistant due to its higher alloy content. Both hold their value in precious metal weight.
Why it’s great
- Solid 10K or 14K gold with no plating to wear off over time
- Multiple karat and color options (yellow, rose, white) plus three size choices
- Daily-wear tested for over 7 months with no visible degradation
Good to know
- Reverse side is completely plain with no design
- 1.5″ diameter can feel heavy for smaller frames or thinner chains
3. 1 oz .999 Aztec Calendar Authentic Silver Round
This is a pure .999 fine silver round manufactured in the USA, weighing exactly 1 Troy Oz, and struck with the Aztec Calendar design on one face. Unlike the pendant-style pieces that are cast with a bail, this is a coin round—thicker, heavier, and designed primarily as a bullion piece that can also be worn if you add your own bezel or chain. The .999 purity is significantly higher than sterling silver, giving it a brighter white luster and a softer feel that can scratch more easily but tarnishes at a much slower rate.
Buyers consistently praise the level of detail on the strike, with the central Tonatiuh face and the surrounding glyph rings rendered with a sharpness that only a struck coin can achieve. The reverse side is typically blank or carries a secondary design, unlike the pendant castings. This is not the most comfortable piece to wear under a shirt due to its thickness, but its bullion value means it can serve double duty as both adornment and a liquid asset.
This round is ideal for collectors who want a silver piece that holds intrinsic melt value, or for someone who plans to mount it in a custom bezel rather than using a pre-attached bail. The .999 purity ensures it will never cause skin discoloration, and the design is among the most detailed available in this price range.
Why it’s great
- Pure .999 fine silver with intrinsic bullion value as a 1 Troy Oz round
- Struck coin construction yields exceptionally sharp engraving detail
- Manufactured in the USA with verifiable silver purity
Good to know
- Not a pendant—requires a separate bezel or chain attachment to wear
- Thicker and heavier than cast pendants, less comfortable for daily wear
4. AFFY 14K Gold Plated 925 Sterling Silver Aztec Mayan Sun Calendar Pendant
The AFFY pendant uses a .925 sterling silver core with a 14K gold plating, offering the look of solid gold at a substantially lower price point. The pendant is paired with an 18-inch rope chain, and the gold plating gives it a bright, blingy shine that several buyers compared to the aesthetic of Aztec gold seen in pop culture. When polished, the pendant catches light well and appears convincing as a solid gold piece from a short distance.
However, the durability of the plating is the main concern. A few verified buyers reported that the gold color faded noticeably within a month of regular wear, while others were satisfied with the longevity when worn only for going out rather than daily use. The craftsmanship is described as excellent by those who received a good unit, with proper weight and a secure bail attachment. The contrast between the recessed engraving and the gold surface is strongest when the piece is new.
This pendant works best as an occasional-wear piece for someone who wants the visual impact of gold without the cost of solid gold. The sterling silver base means it won’t turn skin green even if the plating wears thin, and it can always be re-plated by a jeweler. It’s a solid mid-range option for those who prioritize appearance over long-term wear resistance.
Why it’s great
- 14K gold plating over genuine .925 sterling silver prevents skin discoloration
- Comes with an 18-inch rope chain, ready to wear out of the box
- Strong initial shine and convincing gold appearance
Good to know
- Gold plating may fade or wear thin with frequent daily contact and oils
- Some buyers reported inconsistent plating quality between units
5. JERWLI S925 Sterling Silver Aztec Calendar Pendant with Mixed Symbol Options
JERWLI offers this S925 sterling silver pendant as part of a larger collection that includes other symbol pendants like the Cross, Memento Mori, Lion, Star of David, and Eye of Horus. The Aztec Calendar option is cast in sterling silver and comes with a 22+2-inch stainless steel chain, making it ready to wear immediately. The pendant itself is described as well-made with clean edges, though multiple buyers noted it is smaller than they expected based on the product imagery.
The biggest durability concern comes from a verified buyer whose pendant attachment broke at the bail after two months of regular wear, making it impossible to attach to a chain. This appears to be an isolated structural issue rather than a widespread problem, but it highlights the importance of checking the bail joint on cast pendants. Other buyers praised the necklace as a gift that was well-received, particularly for its range of symbolic options in one purchase.
This is a good choice for someone who wants a sterling silver Aztec Calendar pendant but also appreciates the ability to swap to other symbolic pendants from the same set. The stainless steel chain is more durable than silver for daily wear, and the pendant itself offers decent detail for its slightly smaller diameter. Just inspect the bail attachment point regularly if worn daily.
Why it’s great
- Multiple symbolic pendant options available in the same sterling silver line
- Included 22+2-inch stainless steel chain is strong and tarnish-resistant
- Clean casting with good surface detail for the size
Good to know
- Pendant is smaller than it appears in product photos
- At least one reported instance of the bail attachment breaking after 2 months
6. 1998 Mexico 10 Pesos Coin Pendant Aztec Sun Stone Calendar
This pendant takes a different approach—it uses a genuine 1998 Mexico 10 Pesos coin that features the Aztec Sun Stone calendar on one face, with a bail attached to turn it into wearable jewelry. The coin itself is legal tender from the Banco de México, giving it an authenticity that cast reproductions cannot match. The copper-nickel alloy of the coin gives it a warm, antique bronze tone that develops a natural patina over time.
Buyers describe it as a great gift that is immediately recognizable as the real Piedra del Sol design. The diameter of the 10 Pesos coin is roughly 28mm, which is slightly over 1 inch, providing adequate surface area for the calendar details to be visible. The reverse side of the coin carries the Mexican coat of arms, adding another layer of numismatic interest that a blank reverse pendant cannot offer.
This is the most budget-friendly entry point in the category, and it carries the distinct advantage of being an actual government-minted coin rather than a commercial casting. The copper-nickel material is durable and resists tarnish, though it will patina with age. Perfect for someone who values authenticity and history over a shiny precious metal finish.
Why it’s great
- Genuine 1998 Mexican 10 Pesos coin with official Banco de México minting
- Copper-nickel alloy is durable, tarnish-resistant, and develops a nice patina
- Reverse side features the Mexican coat of arms for added interest
Good to know
- Copper-nickel material is not a precious metal and has minimal melt value
- Smaller diameter than cast sterling pendants, less engraving real estate
7. Seiyang Aztec Calendar Necklace Sterling Silver Round Pendant
The Seiyang pendant is an entry-level sterling silver option with a 2mm 22+2-inch rolo chain included. The pendant is described as having a very rustic and antique look with lots of intricate detail on the face, and the chain offers a classic herringbone-style link that pairs well with the round shape. Some buyers found the small size—particularly the shorter chain length—to be a limitation, especially for those who prefer a longer drop or a larger statement piece.
The main concern with this pendant is finish longevity. One verified buyer reported that the color faded noticeably after a month, which suggests the piece may have a plated coating rather than a solid sterling polish, or that the sterling itself was low-grade. Another buyer felt the pendant was overpriced for its size and construction quality. On the positive side, buyers who received a good unit praised the genuine feel and the excellent chain quality.
This is the most affordable sterling silver option in the list, making it a reasonable entry point for someone who wants a silver Aztec Calendar pendant without spending on a mid-range piece. However, the inconsistent quality reports mean it’s worth inspecting closely upon arrival. If you get a good unit, the antique look is genuinely appealing; if not, the return process may be necessary.
Why it’s great
- Affordable entry into sterling silver Aztec Calendar pendants
- Rustic antique finish with good surface detail when the casting is clean
- Includes a matching 22-inch rolo chain
Good to know
- Some buyers reported color fading or tarnishing within a month of wear
- Chain is shorter than some may prefer, and the pendant is relatively small
