Brand efficiency

Le 31 is Simons' in-house brand, bypassing wholesale markups for a direct-to-consumer price.

Why this is supported

The ring is sold under Simons' exclusive in-house brand, Le 31, which avoids traditional retail markups.

Le 31 bypasses the wholesale and brand-licensing markups that push third-party signet rings north of CAD 60 for equivalent specs; CAD 39 essentially functions as a direct-to-consumer price with the convenience of a national department store return policy.Value compared to similar stainless steel signets — le_31_private_label_pricing

This pricing structure allows the ring to offer substantial value despite its low price.

Stone type

Stainless steel band with a synthetic polished stone

Why this is supported

Le 31 Q&A confirms that

similar Le 31 rings from the same line use faux gemstone for their textured ring [3]What specific type of black stone is used (e.g., onyx, hematite, or synthetic)?

and deep research adds that

the high polish of the synthetic surface often appears more reflective and uniform than its mined counterpartValue compared to similar stainless steel signets — synthetic_stone_trade_off

, so the stone is a deliberately chosen synthetic for uniformity and polish.

The ring is solid stainless steel with no plating, eliminating the risk of plate wear exposing allergenic base metals underneath.

no reference to plating, so the band is solid metal through its thickness — there is no risk of a gold or rhodium plate wearing off to reveal a different color underneathHow stainless steel rings hold up over time — solid_body_no_plating

Stainless steel is generally hypoallergenic, but the product description cautions that some alloys may contain trace nickel, so buyers with severe nickel sensitivity should consult a jeweler.

generally considered hypoallergenic and safe for most people with sensitive skin. However, we cannot guarantee it is completely nickel-free as some stainless steel alloys may contain trace amountsIs the ring hypoallergenic and nickel-free for sensitive skin?

Furthermore, the chromium oxide layer on stainless steel is self-repairing and reduces metal ion release, and the band is rust- and tarnish-proof, preventing corrosive byproducts that could irritate sensitive skin even with daily exposure to sweat and humidity.

While many rings at this price use electroplated alloys, the stainless steel construction avoids the chipping and tarnishing common in cheaper rings.

Stainless steel is uncommon at CAD 39 — most rings in this band rely on electroplated brass or zinc alloy, which are prone to chipping and tarnishing within months; the solid stainless construction means the ring maintains its color and resists wear better than the vast majority of fast-fashion alternatives.Value compared to similar stainless steel signets — stainless_steel_over_plated_alloys

Similarly, the stone—likely a synthetic—addresses the fragility of natural onyx.

Resulting in a ring that delivers better long-term appearance than its price suggests.

The stainless steel band is solid throughout with no plating, so surface scratches remain the same silver tone.

The stone is a faux gemstone or glass, chosen for its uniform reflectivity and durability.

The unspecified black stone is almost certainly a faux gemstone or glass, which is actually an advantage at this price: it eliminates the care and fragility concerns of natural onyxValue compared to similar stainless steel signets — synthetic_stone_trade_off

The steel's chromium content also provides self-repairing corrosion resistance.

Stainless steel contains at least 10.5% chromium, which forms an invisible, self-repairing chromium oxide film on the surfaceHow stainless steel rings hold up over time — chromium_oxide_self_passivation

And the stone and metal wear at the same pace, avoiding uneven patina.

the two materials wear at nearly the same pace — the ring won't develop the uneven patina where a hard gemstone stays flawless while its soft setting becomes a scratched messHow stainless steel rings hold up over time — mohs_match_between_stone_and_metal

This ensures the ring ages evenly and consistently.

Care

Stone (Mohs 6.5–7) resists scratches and wears evenly with the band; gently clean with soap and water

Sizing

Available in US sizes 8–12; runs true to standard sizing but resizing limited by bezel setting.

Why this is supported

According to the brand's Q&A,

Stainless steel rings in this style typically run true to standard US sizingDoes the ring size run true to standard US sizing, or should I size up/down?

. However, resizing is not straightforward. As the Q&A adds,

Stainless steel can be resized, but if the stone is set in a bezel or prong, significant size changes may require resetting or risk damaging the stone.Can the ring be resized by a jeweler, or is the design fixed?

. Therefore, choosing the correct initial size is crucial.

Cleaning

Clean with a soft cloth and mild soapy water; avoid harsh chemicals, ultrasonic, and steam cleaners.

Harsh treatments are warned against:

Storage

Store separately from harder items; the stone and steel wear evenly due to similar hardness.

Maintenance

Solid, rust-proof steel and resilient synthetic stone mean less upkeep than silver or plated rings.

Why this is supported

The stainless steel band is solid without plating, so

there is no risk of a gold or rhodium plate wearing off to reveal a different color underneath, and any surface scratches that accumulate over years remain the same silver tone, allowing a jeweler's polish to restore a mirror finish.How stainless steel rings hold up over time — solid_body_no_plating

Additionally, the steel is passively corrosion-resistant:

this barrier stops oxygen and moisture from reaching the iron in the alloy, making the ring essentially rust- and tarnish-proof in normal wear — it can handle hand washing, sweat, and humidity without the discoloration that silver or brass would develop.How stainless steel rings hold up over time — chromium_oxide_self_passivation
