Jacob Necklace

The Jacob Necklace by Midi34 is a 79 CAD Canadian-made piece featuring a black onyx pendant on a 316L stainless steel chain that resists scratches, tarnish, and corrosion, with a snap hook closure for a utilitarian look and a 21.75-inch length that places the pendant at the collarbone (non-adjustable). While the steel is hypoallergenic and durable against water and sweat, buyer reports indicate the chain is fragile and the stones may loosen, presenting a tradeoff between material resilience and construction reliability.

Durability

316L steel resists scratches, tarnish, corrosion, and is stronger than sterling silver.

Why this is supported

316L stainless steel has a Mohs hardness of about 5.5, over twice that of sterling silver, so the necklace resists scratches from daily wear. The alloy contains chromium that forms a passivation layer preventing tarnish, and molybdenum (2-3%) provides resistance to chlorides in sweat and water. With a tensile strength of ~515 MPa, it is about 70% stronger than sterling silver, meaning the chain is inherently resistant to stretching. The silver-tone color runs throughout the material, not as a plated layer, so it will never wear off.

Chain reliability

Users report the chain is fragile and breaks with daily wear.

• r/GDragon — thread↗

Why this is supported

Despite the material's strength, several buyers report that the chain breaks during normal daily wear, pointing to the thin box-link construction as the weak point. As noted by a buyer:

The chain is fragile and prone to breakingHow is the quality of the necklace?

This trade-off suggests that while the alloy itself is highly durable, the chain's design may not match that durability.

Pendant position

12x8.5 mm pendant rests at the collarbone and layers under collars.

Why this is supported

The 21.75-inch chain positions the pendant at the collarbone, with the 12x8.5 mm pendant being

low-profile enough to layer comfortably under a shirt collar or to pair with a longer chain without competing for attentionStyling a rectangular onyx pendant for men — pendant_scale_and_layering

. Additionally, the chain length is fixed:

so the fit is predetermined.

Closure style

Snap hook closure gives a utilitarian, rugged look.

Why this is supported

The snap hook closure, described in the product listing,

avoids the dressiness of a traditional lobster clasp, reinforcing a rugged-casual identityStyling a rectangular onyx pendant for men — snap_hook_closure

for an outdoor-inspired feel.

Color versatility

Silver-on-black color scheme pairs with navy, charcoal, olive, or white.

Why this is supported

Research on achromatic finishes confirms that the silver-on-black scheme acts as a neutral base,

The combination of silver-tone stainless steel and a deep black stone creates a monochrome-neutral accessory that integrates seamlessly with navy, charcoal, olive, or white — essentially any palette that avoids strong colors, reducing decision fatigue when building an outfit.Styling a rectangular onyx pendant for men — achromatic_finish

This means it avoids clashing with most common wardrobe colors and serves as a versatile anchor piece.

Closure design

Snap hook closure gives a utilitarian identity suitable for casual and workwear.

Why this is supported

The snap hook closure is analyzed as a key design element:

The snap hook, borrowed from mountaineering and industrial design, pushes the necklace into utilitarian territory; it works naturally with chore coats, overshirts, and denim, and avoids the dressiness of a traditional lobster clasp, reinforcing a rugged-casual identity.Styling a rectangular onyx pendant for men — snap_hook_closure

This identifies the closure as a deliberate styling choice that aligns with a rugged-casual aesthetic rather than a formal one.

Fit

Pendant sits at collarbone on a 21.75-inch chain; not adjustable for length.

Why this is supported

The chain length is described as a specific styling choice:

At 21.75 inches, the chain brings the pendant directly to the collarbone on most men — the sweet spot for sitting visibly above a crewneck sweater or t-shirt neckline while still being long enough to disappear under an open collar for a hidden-worn look.Styling a rectangular onyx pendant for men — collarbone_length_positioning

The pendant itself is compact enough to layer:

Measuring just 12 mm tall by 8.5 mm wide, the onyx pendant stays low-profile enough to layer comfortably under a shirt collar or to pair with a longer chain without competing for attention, making it a subtle anchor piece rather than a statement pendant.Styling a rectangular onyx pendant for men — pendant_scale_and_layering

However, the chain length cannot be changed:

The chain has a fixed length of 21.75 inches (55 cm) and is not adjustableIs the chain adjustable in length or does it have a fixed 21.75" length?

This means the collarbone position is fixed and cannot be modified for different necklines or layering preferences.

Stone authenticity

Black onyx is dyed chalcedony, a permanent treatment accepted since antiquity, requiring no special care.

Origin

Made in Canada by Quebec-based Midi34 and sold through Canadian retailer Simons.

Why this is supported

The necklace's domestic origin is emphasized by its production in Quebec and its availability via Simons:

As a product made in Canada by a Quebec-based label, the necklace carries narrative weight for consumers who seek out local craftsmanship over anonymous imports — a story that can elevate the perception of a simple pendant into an intentional, values-aligned choice.Styling a rectangular onyx pendant for men — midi34_s_domestic_production

This retail channel further verifies the local narrative.

Craftsmanship

Quality concerns

Buyers report a fragile chain and stones that may loosen or fall out.

• r/GDragon — thread↗

Why this is supported

Counter to the craft narrative, some buyer feedback reports durability issues:

The chain is fragile and prone to breaking, and stones may fall out.How is the quality of the necklace?

This creates a tension between the brand's local craftsmanship story and the product's reported robustness.

Hypoallergenic

316L steel's low nickel release and no plating reduce allergy risk.

Why this is supported

The necklace is made of 316L stainless steel, which contains 10–14% nickel but

316L is widely considered hypoallergenic because its nickel release rate is extremely low, so it rarely causes reactions except in those with severe nickel sensitivityIs the stainless steel used nickel-free and hypoallergenic?

. The silver-tone finish is integral to the solid alloy, not a plated layer.

Because stainless steel is a solid alloy with color through its entire mass rather than a plated layer, the silver-toned finish will not fade, rub off, or reveal a different metal underneath over timeHow stainless steel jewelry holds up over time — no_plating_to_wear_off

Additionally, the alloy resists corrosion from sweat and water

and does not tarnish like silver

Unlike sterling silver, which reacts with sulfur compounds in air and sweat to form a black tarnish within weeks of exposure, 316L stainless steel is inherently tarnish-resistant due to its chromium oxide passivation layerHow stainless steel jewelry holds up over time — tarnish_resistance_vs_sterling_silver

. Its hardness also prevents scratches that could create rough edges

Care instructions

Mild soap and water cleaning, dry storage, and separate pouch; onyx color is permanent.

Why this is supported

Catalog verified proper care from the brand's Q&A and gemological analysis. The brand advises,
