Dynamis Round Box Silver Chain 2.5 mm Review

The Round Box Silver Chain 2.5 mm is a chain of 2.5 mm links in 925 Sterling Silver with a High Polish finish and a lobster clasp. It comes in four lengths, 32", 28", 26" and 24", and the price runs from $275 to $295 depending on the length. The listing gives an approximate weight of 16g but does not say which length that figure belongs to, and its opening description is general sales wording rather than detail about the links.

Specifications

Options and pricing

Length is the only option, with four choices: 32", 28", 26" and 24". The price follows the length: $295 for 32", $285 for 28", and $275 for both 26" and 24", so the starting price is $275. Metal, finish, width and clasp each have a single entry on the page. The one weight given, approximately 16g, is not matched to any of the four lengths.

How it compares

The Round Box Silver Chain 1.5 mm is the same link style at $225, with a 1.5 mm width, lengths from 24" down to 16" and a listed weight of 7g. The Cable Silver Chain (2.5 mm) matches this chain's 2.5 mm width at $210, in 26 inch, 24 inch and 22 inch lengths. The Foxtail Silver Necklace with Hook Clasp (2.5 mm) is $325 and lists 22g in 26", a weight tied to a named length.

Shipping and processing

• Processing. The store's shipping policy page says to allow 1-3 business days to process an order once payment is confirmed, or 2-4 business days during sales and holiday peaks, and that some products are made to order only, taking 4-6 weeks of processing on average before they ship (checked 2026-11-07).
• This product page says: "Processing time: 1-3 business days".
• Delivery. The same page gives average shipping times of 1-5 business days within Canada (Canada Post), 1-5 business days across North America (DHL) and 5-7 business days for international tracked shipments, which it says exclude weekends and holidays. It says tracking activates once the parcel has been scanned at the sorting facility and that crossing the border from Canada can take two days.
• Duties and taxes. The shipping policy says "Customs taxes, duties or import charges are included." The refund policy says "The return shipping costs as well as duties and taxes (if apply) are the customer's responsibility." Both are quoted as written.

Returns and warranty

• Returns. The store's refund policy page gives 14 days after receiving the item to request a return. The item must be in the condition received, unworn or unused, in its original packaging and in sellable condition, with the receipt or proof of purchase. Contact the store first: items sent back without a return request are not accepted. An approved refund goes to the original payment method, but items bought on sale are refunded as store credit (an e-gift card) only (checked 2026-11-07).
• Not returnable. The same page says custom products, such as special orders or personalized items, and final sale items cannot be returned. Cancelling an order costs a 7% fee, and the store asks to be contacted within 24 hours of ordering. For exchanges it says the fastest route is to return the item and, once the return is accepted, buy the new one separately. It asks buyers to inspect an order on arrival and to contact the store at once about a defective, damaged or wrong item.

• Warranty. The store's lifetime warranty page covers manufacturing defects and material failures for the lifetime of the original purchaser, starting at the purchase date: for example loose, damaged or missing stones, broken chains, snapped bracelet strands and malfunctioning clasps or hinges, when caused by a manufacturing defect (checked 2026-11-07). Every claim is reviewed case by case and must be approved.
• Not covered. The page lists lost or stolen items; scratches, dents and general wear; tarnishing, oxidization and discoloration; damage from chemicals, moisture, chlorine, perfumes, lotions or cleaning solutions; accidents, misuse or improper storage; third-party repairs, alterations, resizing or cleaning; resold items and items from unauthorized sellers; and "Sample sale, clearance, or final sale items, unless otherwise stated".
• Claims. A claim needs your name, current address, order number or proof of purchase, a description, two clear photos, one photo of the item beside a handwritten note with the order number and, where movement is involved, a video of up to 10 seconds. If a claim is approved the store may repair or replace the piece or issue store credit at its discretion, and it may issue store credit equal to the original value if the piece is no longer available. It offers no rainchecks for discontinued or out-of-stock items.

Care and custom orders

• Care. The FAQ says to use the provided Dynamis polishing cloth to clean the silver or gold areas gently, mild diluted soap with warm water for deeper cleaning, and to dry the piece thoroughly before storing it. It advises avoiding prolonged exposure to moisture, perfumes, lotions, chlorine and harsh chemicals (checked 2026-11-07).
• Tarnish. The FAQ says 925 sterling silver is 92.5% pure silver with a small amount of alloy and that it can tarnish with moisture, air, skin oils, sweat, lotions, perfumes or chemicals. It calls this normal and not a manufacturing defect, and says tarnish can usually be cleaned with a polishing cloth or proper silver-cleaning care. To reduce it the FAQ recommends storing the piece in a dry place, not wearing it while swimming, showering, exercising or applying lotions, perfumes or hair products, and wiping it with the cloth after wear.
• In the box. The FAQ says every Dynamis order arrives in signature Dynamis packaging and includes a polishing cloth.
• Gold versions. The FAQ says the store takes custom orders, including having certain existing Dynamis pieces made in gold, and that gold counts as a custom order. Custom orders start from $2,500, the final price depends on material, size, weight, design complexity and special details, and every custom order is final sale: it cannot be returned, exchanged or cancelled once production has begun. Requests go through the store's contact form (checked 2026-11-07).

Before you buy

Dynamis Jewelry says it is a family-owned brand based in Canada, run by a husband-and-wife team, Stepan and Yuliia. Its About page says the business grew from Stepan's work as a jeweller, that it specializes in solid 925 sterling silver and gold, inspired by faith, and that many pieces are produced in limited quantities. The FAQ says the pieces are not mass produced, and the About page says the name comes from the Greek word dynamis, meaning strength, power, fortitude and the ability to overcome (checked 2026-11-07).

Two points on the store's own pages disagree. The refund policy gives [email protected] for starting a return, while the FAQ gives [email protected], so check the address before you write. And the warranty page covers items bought from Dynamis Jewelry "or an authorized Dynamis Jewelry retailer", while the FAQ says authentic Dynamis Jewelry is sold only through the official website and official Dynamis channels and asks buyers to purchase directly from the store.
