Knowledge of wedding and engagement rings
Because wedding rings are meant to be worn for a long time, the choice of material is very important. Different materials require different looks, durability, price, and maintenance, so you want to choose one that suits your lifestyle and preferences.
If you have metal allergies, it is also important to choose a material that is gentle to the skin. This article provides a detailed explanation of the characteristics of each wedding band material and points to consider when choosing a wedding band, as well as recommended materials.
When it comes to material selection, it is hard to know what to compare. There are four points to keep in mind
Since wedding rings are items that are worn on a daily basis, resistance to scratching and discoloration are important.
Platinum is not only resistant to tarnish, but also durable. Gold-based materials have relatively tarnish-resistant characteristics, but their durability varies depending on the alloy composition, as is the case with white gold. Silver, on the other hand, oxidizes easily and requires frequent care. In addition, different materials such as titanium are extremely durable and have characteristics that resist scratches and discoloration. Wooden rings, however, are susceptible to water and moisture and should be handled with care.
Another important factor is whether the color of the ring blends with your skin. Choosing a material that matches your skin tone may make your hands appear brighter, so please try it on to be sure.
Different materials give different impressions. Platinum and silver give a cool impression, while yellow gold like white gold and champagne gold create a warm atmosphere. Pink gold blends well with the skin and gives a gentle impression. It is important to choose gold that goes well with the accessories you usually wear and your own fashion taste.
Those with metal allergies should pay particular attention to the choice of material for their wedding rings. While platinum, gold, and silver are generally considered less likely to cause allergic reactions, the type and proportion of alloys in these materials can cause allergic symptoms. For example, white gold may be mixed with metals such as palladium and nickel, which can cause allergic reactions in some cases.
If you are concerned about metal allergies, we recommend that you take a patch test beforehand to make sure the material is suitable for your skin. For those with metal allergies, materials such as titanium and stainless steel, which are also used in medical instruments, are suitable. These are less likely to cause allergic reactions and can be worn with peace of mind. Wooden rings and rings with designs that combine different materials are also allergy-free and can be considered as options, as long as they do not use any metal.
It is important to choose the material of your wedding band according to your lifestyle. For example, if you do a lot of manual labor on a daily basis, we recommend platinum or K18 (18k gold) gold-based materials, which are scratch-resistant. K18 in particular is a unit of gold purity, meaning that 751 TP3T of the total is gold. Overseas, gold is the most common material for wedding rings, and there are many variations such as white gold and pink gold. White gold has a white shine similar to platinum, but tends to be lighter and more reasonably priced.
Platinum and gold are also easy to process and offer a wide range of design options. Wooden rings, on the other hand, are sensitive to water and moisture, making them unsuitable for professionals who frequently wash their hands, but they can be worn on special occasions as a unique and different material. The width of the ring also affects lifestyle. For example, a thicker ring, such as 6 mm wide, has a strong presence and is recommended for men. However, the width that suits you will vary depending on the shape of your fingers and the size of your hands, so it is recommended that you try on the ring to confirm its suitability.
The materials used for wedding rings tend to be those of high value, such as platinum and gold. In addition to these, materials that take into account metal allergies and different materials with unique designs are also popular.
Platinum is highly popular as a standard material for wedding rings, symbolizing "eternal love" due to its pure white brilliance.
This material is ideal for wedding rings that will be used for a long time in daily life, as it is highly durable with little risk of tarnishing or discoloration. Platinum also has properties that make it less likely to cause metal allergies, so even people with sensitive skin can wear it with peace of mind.
For this reason, platinum is an excellent choice for rings that will last a lifetime, combining luxury and practicality.
Kobo Smith Sapporo uses hard platinum 950, which is even stronger.
Platinum is especially recommended for those seeking a wedding band that will not tarnish and will last a long time.
It is also gentle to the skin and suitable for those who are concerned about metal allergies, allowing it to be worn on a daily basis with peace of mind. Its elegant and refined white luster makes it easy to match with any attire, making it ideal for those who prefer a calm and mature atmosphere.

Yellow gold is an alloy of gold mixed with silver and copper, and is suitable for jewelry because it is harder than pure gold. yellow gold, such as K18, is one material that is relatively resistant to tarnishing, but this does not mean that it does not tarnish at all.

Pink gold is a material with a warm pink color, made by blending gold with copper and a small amount of silver.
The gold content of common pink gold is 75% (K18), and the color varies depending on the percentage of copper. The higher the copper content, the more reddish the color, and the lower the copper content, the lighter the pink color. In addition to blending well with the skin, it is chosen by many women for its soft, feminine appearance.

Silver is an unusual material for wedding rings, but its affordability and variety of designs make it a popular choice for couples seeking individuality.
While silver has one of the strongest shines among metals, it has the disadvantage of being easily oxidized and darkened. Therefore, frequent care is essential. You can maintain its beautiful shine by cleaning it with warm water in which a neutral detergent has been dissolved and polishing it with a silver polishing cloth. Also, be careful in places that contain sulfuric components, such as hot springs, as they tend to discolor easily.

Wooden rings are characterized by their natural texture and warmth, and offer unique designs. Since no metal is used at all, even those with metal allergies can wear them with peace of mind, which is a major attraction.
However, wood is a sensitive material that is vulnerable to water and shock, so care should be taken in its daily use. We recommend that you remove the ring during sports, when carrying heavy loads, or in situations where you have a strong grip on a bicycle. With proper care, it will become a special piece that can be used for a long time.

It also has the property of being resistant to discoloration, making it easy to maintain its beautiful luster.
