Verified claims

Versatility

The black stone signet works across streetwear, tailoring, and day-to-night settings.

Placement

Worn on the pinky for heritage or index for a bold statement.

Proportion

The 16 mm stone fits proportionally on ring sizes 8–12, bold on size 8, tailored on size 12.

Brand efficiency

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

Stone type

Stainless steel band with a synthetic polished stone

Care

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

Value

At CAD 39, the 16 mm stone face undercuts natural-stone signets (CAD 65–80)

Sizing

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

Cleaning

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

Storage

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

What a 16 mm stone looks like on the hand

• At 16 mm, the polished black stone catches light from conversation distance without projecting 'jewelry' in a self-conscious way — this is the size where a signet ring transitions from afterthought to quiet mainstay, making it a safe choice for someone new to the style.
• Men's signet ring stone faces typically range from 10 mm (delicate) to 20 mm (statement), so this 16 mm width lands right in the center — large enough to feel intentional and offer a solid visual anchor, yet small enough to avoid vintage or costume excess.
• Since the ring is available in US sizes 8 through 12, the 16 mm stone covers proportionally more of a size 8 finger, creating a bold, nearly full-finger look, while on a size 12 finger it leaves more negative space and reads as a more tailored, classical proportion.

How stainless steel rings hold up over time

• The product description states only 'Stainless steel' with 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 underneath, and any surface scratches that accumulate over years remain the same silver tone, allowing a jeweler's polish to restore a mirror finish.
• Stainless steel's tensile strength (typically 500–750 MPa for common 304 alloy) vastly exceeds that of gold or silver, so a direct impact that would flatten or twist a precious-metal signet ring leaves this one unscathed; the 16 mm stone setting is firmly supported by a band that holds its shape under daily knocks.
• Stainless steel contains at least 10.5% chromium, which forms an invisible, self-repairing chromium oxide film on the surface; 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.
• With the black stone at an estimated Mohs 6.5–7 and the stainless steel band at 5.5–6.5, 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 mess, so the whole piece ages with a cohesive character.

Value compared to similar stainless steel signets

• Most men's signet rings priced under CAD 50 use stone faces of 10–14 mm; the 16 mm width here is a deliberate step up that reads as more traditional and authoritative without adding cost, effectively delivering a premium proportion at an entry-level price.
• At CAD 39 (roughly USD 28), this ring is priced lower than many US-based competitors after currency conversion, giving Canadian buyers an implicit discount versus shopping American brands — and making it an easy cross-border add-on for US customers ordering from Simons.
• 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 onyx, while the high polish of the synthetic surface often appears more reflective and uniform than its mined counterpart.
• As Simons' exclusive in-house brand, 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.
• 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.
• Sterling silver black onyx signet rings with 14–16 mm faces typically start at CAD 65–80 on Amazon and Etsy, while 14k gold-plated options land around CAD 50–70; the stainless steel Le 31 ring undercuts both by $10–$40 while offering comparable weight and a hyper-black stone finish.
