They are perfect for jewelers, recyclers, coin dealers, or anyone that needs a convenient, easy-to-carry magnet to test for iron, nickel, or cobalt content. Featuring a durable N40 neodymium magnet housed in a plated metal shell, it has a pull force of over 2 pounds. Determine if jewelry is silver or gold plated by testing if ferrous metals are used as the base metal (excluding some nickel alloys). If a magnet responds to jewelry, it is not fine silver or anything near pure gold. The same is also true of brass and bronze antiques, many are just brass plating over steel or iron. This strong magnet can also be used to determine polished aluminum from stainless steel in most cases, and is very handy for testing industrial metals for recycling.The key magnet features a powerful N40 grade (2 lbs minimum pull strength) neodymium rare earth magnet encased in a plated steel housing for durability and comes with a stainless steel split ring.Product Specifications Type: Neodymium Magnet KeychainMaterial: N40 NeodymiumDimensions: 0.47 inches wide at its widest point x 1.57 inches long (12 x 40 mm)Weight 0.6 oz (18 g) ## Features - 【Product Size】0.47 x 1.57 inches with N40 Neodymium Magnets; Package: 1 Piece; Pull Power: Over 2 pounds per magnet. This gold testing magnet is the perfect size and strength for identifying fake silver and gold jewelry! - 【Jewelry & Coin Testing】Identify fake/plated jewelry, which often has steel or nickel alloys as the base material (some alloys, like nickel-silver and German silver are non-magnetic, despite having ferrous metals present). Generally, the magnet test is only the first test performed when verifying the authenticity of coins and jewelry, before density and acid testing. - 【Precious Metals Testing】Identify/sort chrome plated items from polished aluminum, silver, and non-magnetic grades of stainless steel (chrome plating requires a nickel layer, which is magnetic). Identify and sort solid brass and bronze from steel-plated items (handy in the antique market and hardware store). - 【Practical Magnetic Keychain】This magnetic keychain is strong, small, light in weight, and easy to carry. You can put it in your pocket or purse when you go out. It provides you with a versatile multi-functional magnetic testing tool. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08QV75QMX | | ASIN | B08QV75QMX | | Additional Features | Magnetic | | Age Range Description | Adult | | Best Sellers Rank | #162,816 in Arts, Crafts & Sewing ( See Top 100 in Arts, Crafts & Sewing ) #83 in Jewelry Gold Testers | | Brand Name | Envistia | | Closure Type | Split Ring | | Color | Silver | | Customer Reviews | 4.6 4.6 out of 5 stars (931) | | Date First Available | March 23, 2021 | | Department | mens | | Fit to Size Sentiment | Good Fit | | Garment Size Country | United States | | Included Components | stainless steel split ring | | Item Dimensions | 1.57 x 0.47 x 0.47 inches | | Item Shape | Rectangular | | Item model number | Kmt-2023 | | Manufacturer Part Number | JM-MAG-0004 | | Material Type | Aluminum,Brass | | Number of Pieces | 1 | | Pattern | Solid | | Product Dimensions | 1.57 x 0.47 x 0.47 inches; 0.71 ounces | | Product Style | Brass | | Shoulder to Bottom Hem Length | 40 millimeters | | Style Number | Kmt-2023 | | Theme | Silver | | UPC | 732387205982 | | Unit Count | 1 Count | ## Product Details - **Color:** Silver - **Included Components:** stainless steel split ring - **Material:** Aluminum,Brass - **Special Feature:** Magnetic - **Theme:** Silver ## Images ![Mall Keychain Magnet for Testing Gold, Silver, Brass, Precious Metal & Jewelry, Non-ferrous metal verification - Image 1](https://m.media-amazon.com/images/I/61nirqq5jjL.jpg) ![Mall Keychain Magnet for Testing Gold, Silver, Brass, Precious Metal & Jewelry, Non-ferrous metal verification - Image 2](https://m.media-amazon.com/images/I/41StdVJLeFL.jpg) ![Mall Keychain Magnet for Testing Gold, Silver, Brass, Precious Metal & Jewelry, Non-ferrous metal verification - Image 3](https://m.media-amazon.com/images/I/41V7hOVbSNL.jpg) ![Mall Keychain Magnet for Testing Gold, Silver, Brass, Precious Metal & Jewelry, Non-ferrous metal verification - Image 4](https://m.media-amazon.com/images/I/31iw5vR7R8L.jpg) ![Mall Keychain Magnet for Testing Gold, Silver, Brass, Precious Metal & Jewelry, Non-ferrous metal verification - Image 5](https://m.media-amazon.com/images/I/31DMJDMjf0L.jpg) ## Frequently Bought Together - Envistia Mall Keychain Magnet for Testing Gold, Silver, Brass, Precious Metal & Jewelry, Non-ferrous metal verification - Presidium Instruments Gem Tester II (PGT II) with Assisted Thermal Calibration (ATC) for Identifying Diamonds/Moissanites and Common Colored Gemstones - Professional Gold, Silver, Platinum Jewelry Testing Kit with Stone Instructions and Box with 30X Eye Loupe Magnifier Precious Metals 10K 14K 18K 24K 999 925 Scrap --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hu/products/267530708-mall-keychain-magnet-for-testing-gold-silver-brass-precious-metal](https://www.desertcart.hu/products/267530708-mall-keychain-magnet-for-testing-gold-silver-brass-precious-metal) --- *Product available on Desertcart Hungary* *Store origin: HU* *Last updated: 2026-08-08*
