How To Personalize Your Cobalt Wedding Band With Engraving

Cobalt wedding bands are a popular alternative to gold, silver, and platinum wedding rings. They are made from a hard, lustrous, silver-grey metal that is combined with other metals such as chromium, tungsten, or iron to increase its durability. While cobalt rings are scratch-resistant, they cannot be engraved using traditional techniques and tools due to their density and scratch-resistant properties. Laser engraving is the most effective method for engraving cobalt wedding bands.

Can cobalt rings be engraved using traditional techniques?

Cobalt rings are made from a highly durable cobalt alloy that is extremely strong, scratch-resistant, and shatterproof. The metal is harder than precious metals like platinum, gold, and silver, and is also used in medical implants and the dental industry.

Due to its extreme strength and scratch resistance, engraving cobalt rings using traditional techniques and tools is considered a difficult and risky process. One jeweler has said that cobalt chrome "will absolutely laugh at HSS tools and I doubt carbide will work either". Another jeweler has said that "if HSS won't cut it, you can pretty much write it off as not possible".

However, one company does offer traditional engraving upon request, although they suggest laser engraving because it offers a bolder appearance on the ring. Laser engraving is a modern technique that can effectively etch strong, dense metals.

What are the pros and cons of engraving cobalt rings with lasers?

Cobalt rings can be engraved with lasers, but traditional engraving methods do not work on them due to their durability and hardness. Here are some pros and cons of engraving cobalt rings with lasers:

Pros

• Cobalt rings are hard and durable, making them a good choice for people who lead active lifestyles or work with their hands. Engraving with lasers can create precise and detailed designs that will last a long time without wearing off.
• Cobalt is hypoallergenic and often used in medical devices, so engraving with lasers can ensure that the ring remains safe for people with sensitive skin or metal allergies.
• Laser engraving is a precise method that can create intricate designs, allowing for customisation and personalisation of the ring.

Cons

• Laser engraving can be more expensive than traditional engraving methods due to the specialised equipment and skills required.
• The hardness of cobalt may limit the depth and complexity of the engraving, and once scratched, cobalt rings cannot be refinished to remove those scratches.
• While laser engraving can be done on cobalt rings, the range of designs available for cobalt rings is generally more limited compared to traditional metals like gold or silver.

What are the best engraving ideas for cobalt wedding bands?

Cobalt wedding bands are a popular choice for couples due to their affordability, durability, and resemblance to precious metals like platinum or white gold. While cobalt bands are challenging to engrave due to their density and hardness, laser engraving techniques can successfully etch designs onto these rings. Here are some thoughtful engraving ideas for cobalt wedding bands:

Traditional Engravings:

• The date you met or your wedding date.
• Your initials or your partner's.
• Religious verses or symbols.
• Romantic quotes or snippets from poetry.
• "The beginning of forever."
• "To the moon and back."
• "You're my everything."

Companion Engravings:

• Little Spoon / Big Spoon.
• Love Is Patient / Love Is Kind.
• I Am My Beloved's / My Beloved Is Mine.
• Yin/Yang symbols.
• GPS coordinates of a significant location, like where you met.
• "I love you" written in Morse code.

Fun and Creative Ideas:

• A reference to your favourite TV show or movie.
• An inside joke or a private nickname.
• The year of your wedding in Roman numerals.

How does cobalt compare to other metals when it comes to engraving?

Engraving is the practice of incising a design on a hard, usually flat surface by cutting grooves into it. It is one of the oldest techniques in printmaking.

Cobalt is a hard, lustrous, silver-grey metal, considered a "transition metal". It is combined with other metals, such as chromium, tungsten, or iron, to create jewellery.

Cobalt is a very hard metal, which makes it difficult to engrave. In fact, it is so hard that conventional tools cannot engrave it. It is comparable to tungsten in this regard, which is also very difficult to engrave. However, it is possible to engrave cobalt using a laser.

Compared to other metals, cobalt is harder than gold, silver, and platinum, which are more commonly used for engraving. This is because these metals are softer and easier to cut into. Gold, silver, and platinum have long histories as materials for engraving, whereas cobalt is a more recent addition to the world of jewellery-making.

Cobalt is also harder than titanium, which is another metal that can be engraved. Titanium is often used for engraving because it is hypoallergenic, but cobalt alloys that do not contain nickel can also be hypoallergenic.

In terms of weight, cobalt is lighter than gold, platinum, and palladium, but heavier than titanium.

Overall, cobalt is a very hard metal that is difficult to engrave with conventional tools. It is harder than many other metals commonly used for engraving, such as gold, silver, and platinum, but it can be engraved using lasers.

What is the process of resizing a cobalt ring?

Cobalt rings are resizable, but the process is challenging due to the metal's toughness and high melting point. The alloy used for jewellery varies from batch to batch, and there is no suitable cobalt solder that can be used without issues with colour and hardness. Therefore, resizing a cobalt ring often results in damage to the ring's design.

When resizing a cobalt ring, a jeweller with experience and expertise in resizing such rings is required. The process involves heating the ring to extreme temperatures to increase or decrease its size. While it is possible to resize cobalt rings without significant damage, especially if they have simple designs, it is not easy to do so without distorting intricate patterns or settings. For this reason, many jewellers will refuse to resize cobalt rings or advise customers to purchase a new ring.

It is recommended to resize cobalt rings by a maximum of half a size to one full size to prevent substantial damage. If a more significant size change is required, the ring may need to be cut and re-soldered, which can leave visible marks. Additionally, if the ring has precious stones, they will need to be reset, and the setting may need to be changed to accommodate the new size. This process is labour-intensive and can result in an uneven stone setting.

In summary, while it is technically possible to resize cobalt rings, it is a difficult and specialised process that may result in damage to the ring. It is essential to ascertain the resizing policy from the jeweller before purchasing a cobalt ring, as it is likely that any resizing will need to be done by returning the ring to the retailer.
