Wedding Rings
The majority of Costco’s wedding bands are offered in three precious metal options: 14ct gold, 18ct gold, and 950 platinum. Discover the natural beauty and characteristics of each, and decide which one is best for you. All 14ct and 18ct white gold that Costco offers has been rhodium plated to enhance lustre, durability and brightness to the gold. This does not affect the percentage of gold in the item. Some 950 platinum is also finished with rhodium for the same reason. If an item is rhodium plated, it will be noted on the product page.
Whether you’re purchasing a band to wear alone, with an existing wedding ring, or to complement your partner’s ring, you’ll find exactly what you’re looking for at Costco. We carry a broad selection of fine gold and platinum bands, for both men and women, in a variety of widths and finishes. Choose from a classic gold band with a mirror finish, a two-tone band with filigree detailing, or a platinum band with diamond inlay. Whatever your choice, you can shop with complete confidence, knowing that Costco offers only the highest quality rings at the lowest possible price.

14ct Gold
14ct gold is comprised of 58% pure gold. It is blended with a higher percentage of alloy metals, which makes it lighter and substantially stronger than 18ct gold. Its strength makes it more durable and scratch resistant, and less likely to bend. 14ct gold wears well, and is often the choice for jewellery that is worn on a daily basis.
Each piece of 14ct gold jewellery sold by Costco is hallmarked. Unlike our gold jewellery that includes gemstones or diamonds, our gold-only jewellery does not come with any type of paper authentication, such as a certificate or Article of Description. In the case of our gold-only jewellery, the stamp itself, is the actual authentication.
18ct Gold
18ct gold is comprised of 75% pure gold. It is blended with a lower percentage of alloy metals, which makes it heavier and softer than 14ct gold. Jewellery crafted from 18ct gold can be more susceptible to scratches. It also has a slightly warmer hue, which is appealing to many people.
Each piece of 18ct gold jewellery sold by Costco is hallmarked. Unlike our gold jewellery that includes gemstones or diamonds, our gold-only jewellery does not come with any type of paper authentication, such as a certificate or Article of Description. In the case of our gold-only jewellery, the stamp itself, is the actual authentication.
Platinum
950 platinum jewellery is comprised of 95% pure platinum and 5% alloy. Prized for its purity, it is the strongest, heaviest, and most durable of the precious metals offered by Costco. Platinum has a clean silvery-white colour and a natural sheen. It rarely tarnishes, which makes it a wonderful low maintenance option for jewellery. Not only does platinum wear well, it also has natural hypoallergenic characteristics.
Although platinum is stronger than gold, it is a softer metal and scratches more easily. Over time, platinum jewellery will lose some of its sheen and develop a softer patina. Many people prefer this look, but if you’d like to restore your platinum jewellery to its original high-gloss finish, simply have it re-polished or re-plated by a professional jeweller.
Platinum is a rare metal, which creates a high market demand. And because metal is priced by weight, the density of platinum adds to its cost. Due to its exceptional strength and durability, many people consider platinum to be worth the price.
Each piece of platinum jewellery sold by Costco will be stamped 950. Unlike our platinum jewellery that includes gemstones or diamonds, our platinum-only jewellery does not come with any type of paper authentication, such as a certificate or Article of Description. In the case of our platinum-only jewellery, the stamp itself, is the actual authentication.

Metal Care & Cleaning
Avoid all harsh chemicals such as bleach, ammonia, chlorine, hair spray, and perfume, as they may cause permanent damage to metals. Do not wear your gold jewellery while using a pool or hot tub.
Gold jewellery can be cleaned using a solution of lukewarm water with a drop of mild soap. Place the jewellery in the solution, and let it soak for 10 to 30 minutes. If necessary, you can gently wipe the jewellery with a soft-bristle brush or cotton cloth. Rinse the jewellery thoroughly, and ensure that it is completely dry before storing. If you choose to use commercial jewellery cleaner, be sure to use one that is specifically designed for use on gold jewellery. Some solutions do contain chemicals that can cause permanent damage to certain metals, as well as sensitive gemstones and pearls. Use with caution.
Maintenance
You can easily maintain the beauty of your gold jewellery by having it polished by a jeweller. A basic polishing will remove any nicks and scratches, and restore its natural lustre. You can have your jewellery polished every 1-3 years, depending on usage. Over time, white gold can lose some of its lustre and bright white colour. You can restore your gold jewellery to its original brilliance by having a jeweller re-plate it with rhodium, which will give it a shiny protective finish that will last for years.
