Rings, and especially wedding rings, take on a lot of daily wear, so choosing a strong gemstone is crucial. We work with diamonds, moissanites and sapphire, as these stones are the strongest as well as beautiful. We’ve put together this guide for you to help you understand how gemstones rank in hardness. Softer stones can be great for other jewelry like earrings and necklaces, or even special occasion rings that won’t be worn day to day. 

What is the Mohs Hardness Scale for Gemstones?

When selecting the perfect gemstone for your jewelry, especially in rings, it can be helpful to consult the Mohs Hardness Scale. This fundamental scale, developed in 1812 by Friedrich Mohs, provides a comparative measure of a mineral's resistance to scratching. The Mohs Scale characterizes the scratch resistance of various minerals through the ability of harder materials to scratch softer ones. It serves as a guideline for determining the durability and maintenance needs of gemstones, which can be key information when choosing stones for jewelry that will be worn daily like wedding and engagement rings. Friedrich Mohs, a German mineralogist, introduced the scale to provide a straightforward method of comparing mineral hardness. Although modern tools and methods can measure hardness more precisely, the Mohs scale remains a popular reference for its simplicity and ease of use.

The scale is composed of 10 reference minerals, each representing a specific level of hardness:

1. Talc

2. Gypsum

3. Calcite

4. Fluorite

5. Apatite

6. Orthoclase Feldspar

7. Quartz

8. Topaz

9. Corundum (Sapphire)

10. Diamond

Each mineral can scratch those below it on the scale. For example, a quartz gemstone, rated at 7, can scratch anything with a hardness of 6 or below but will be scratched by topaz, corundum, and diamond.

For rings, especially wedding bands that are worn consistently, selecting a gemstone with a higher Mohs rating ensures longevity and resistance to everyday wear and tear. Diamonds and Sapphires (Corundum) are very strong stones, their popularity for wedding jewelry can be attributed to how well they wear, as well as their beauty. 

The Strongest Stones

Diamonds, rated at 10 on the Mohs scale, are renowned for their unparalleled hardness and brilliance, and have been a top choice for wedding and engagement rings for many years. Their ability to resist scratches ensures that they maintain their sparkle and shape throughout a lifetime. Due to their incredible physical qualities, Diamonds have also been revered by a multitude of cultures throughout history, from being symbols of status to even being believed to possess special properties. Diamonds were often linked with gold, possibly due to the joint occurrence of diamonds with quartzite, quartz veins and an occasional occurrence of gold in them.

Their incredible ability to catch and refract light, creating that characteristic sparkle has always been captivating. They have come to be seen as symbols of strength, purity and endurance. They are also the April birthstone, and symbolize a sixty year anniversary.

Corundum minerals, which include sapphires and rubies, rate at 9 on the Mohs scale. These stones are excellent choices for rings due to their toughness and vibrant colors. Sapphires are available in a wide range of hues, from classic blue to pink and yellow, offering versatile options for personalizing jewelry. We also particularly love pairing sapphires with mokume gane, a stone in a complimentary color can be perfectly suited to the beautiful mix of metal colors and patterns that characterize our mokume rings. Traditionally sapphires symbolize nobility, truth, sincerity, and faithfulness. They have often been associated with spirituality and connection to the celestial. Sapphire is the birthstone for September, and symbolizes 45th wedding anniversaries.

Another lesser known but amazing option for wedding jewelry is the moissanite. It rates at roughly a 9.5 on the Mohs scale. It was originally discovered by Henri Moissan while examining samples from a meteor crater in Arizona in 1893.  Most moissanite available today is lab grown, as it is made of an incredibly rare naturally occuring material, whose origins have been traced to meteorites. Moissanites have a beautiful sparkling quality, evoking the material’s origins of outer space. They are often visually indistinguishable from diamonds, but being lab grown, are sourced sustainably and are a much more affordable option. 

Understanding the Mohs Hardness Scale is invaluable for anyone involved in jewelry design or purchasing. By considering the hardness of gemstones, you can select stones that not only complement your aesthetic preferences but also suit your lifestyle and durability needs. Our mokume gane rings are made at heirloom quality, crafted with care and skill to ensure they last you this lifetime and beyond. Choosing stones that will stand the test of time like mokume gane itself will help you create jewelry that is not only stunning but also built to last, ensuring that your pieces remain cherished for years to come.

Mokume Gane rings are the perfect material for unique wedding rings, and a wonderful combination of symbolism and high quality craftsmanship that will stand the test of time.

The process of making mokume itself is at its’ core about creating a strong bond. Taking sheets of different precious metals such as various colored golds, palladium, and silver, and forging a connection between them with heat and pressure to create a billet. This part of the process is the foundation for the ring, requiring great skill and attention. 

Mokume Gane rings are not only beautiful but also durable. Like a traditional style band, the precious metals wear well and are made to be heirloom quality. We believe in making pieces that will last a lifetime and beyond. 

Each mokume ring is carefully handcrafted, so each is unique! This quality is perfect for wedding rings, as even within a matched set, each ring will have small details that make it one of a kind. 

Each person can choose designs to both suit their own tastes and style but also to match with features of their partner's ring, keeping a strong connection to the other. For example, choosing to have the same pattern for both rings, but each picking a different palette (or vice versa).

Finish is also important to consider, as oxidizing makes a distinct visual difference with darkened outlines. Two rings made in the same palette can even look different, if one person prefers a lighter look than the other they can choose the non oxidized option.

If both wedding rings are made in the same palette, they will be cut from the same billet, further symbolizing the bond between the two rings and the relationship between the people wearing them. If the same pattern is chosen, the rings will be matched to each other in a unique design that only you two share. 

Our mokume gane rings are each lovingly made by hand. They are beautiful, unique, and made to last and to be handed down for generations to come. 

One of the first choices you may make in designing your custom mokume gane ring is which palette you would like! There are many possibilities, each metal combination offers a different look.

Check out our gorgeous Design Guide, which shows the metals used in each of our stocked palettes. All of our mokume gane is made with only precious metals, recycled and nickel free. One of the most beautiful aspects of our mokume work is its multi-colored nature.

We thought we would group our options into a few categories to show the range of options. See what suits your and your partners taste. 

Warm toned palettes:

Red gold forward 

Flame                                             Embers

Yellow gold forward 

Spark                                                   Flare

Generally Warm

 (these palettes have both red and yellow gold, so they vary between leaning toward either color, and Blaze in particular feels very warm and vivid as it’s all gold, no silver)

       Fire                                                Firestorm

Blaze                                              Cinders

Cool/Neutral toned palettes:

Smoke                                                    Ash   

Our palettes are fire themed, as Arn feels drawn to the making process of mokume itself, using heat and fire to bond the metals. So rather than naming based on the wood grain appearance of the patterns, he draws inspiration from the forge itself.

A benefit of a ring made in mokume gane is that they are made with precious metals which inherently offer vivid and lively color combinations. As opposed to an option like damascus, which would always be only shades of gray, as damascus is made in steel. 

Mokume gane wedding rings combine the luxury and beauty of gold and silver as traditional materials, with a more unique and contemporary organic style. They are the perfect choice for the individual who wants to use precious and high quality materials that hold value and stand up to time. 

With our custom design options, you can also choose a completely custom billet if one of our stock options isn’t exactly what you’re envisioning. We can incorporate other precious metals like 18 or 22kt golds or platinum. 

Along with the metal palette, finish affects how the colors of your ring will look! 

Oxidation darkens the silver layers of the ring, and this overall gives the ring a higher contrast look. This is one of Arn’s distinctive design choices that sets him apart from other artists.

Etching is also a consideration with finish, this is part of Arn’s signature in his work, many other mokume makers do not etch their rings, but Arn feels it adds contrast, only enhancing the patterns and bringing out small details that would be harder to see with a smooth finish. Etching also adds to the resemblance the rings have to wood, a trademark element of mokume gane. 

Once you have chosen your palette you can move on to the pattern. We will go into this in our next blog. Please sign up for our mailing list so that you can have new blogs, sales, and news delivered to your inbox.

The tradition of exchanging wedding bands symbolizes a commitment, love, and unity between two people. And there are so many options for finding the perfect rings to symbolize this bond.

Many couples choose their bands together, to find a pair of rings that feel symbolic of each individual, and the connection between them.

There is also a unique appeal of custom made wedding rings, and specialty techniques like mokume gane allow for an added level of personalization.

The Growing Trend of Couples Choosing Wedding Bands Together

In the past, couples have separately chosen each other’s rings, but in recent years, the trend of couples selecting their wedding bands together has gained popularity. This collaborative approach adds an extra personal touch to the rings.

Selecting wedding bands as a couple can be a wonderful unifying experience. It allows partners to discuss preferences, styles, and meanings behind different designs. 

When couples choose their rings together, they have the opportunity to choose what design elements would best symbolize their relationship and the marriage that they are building.

By selecting wedding bands together, couples can also ensure that their rings complement each other aesthetically. This is perfect for a pair who have distinct personal styles and tastes, but would still like their wedding bands to feel like a set.

Exploring Custom Wedding Bands

Custom wedding bands offer couples the flexibility to create rings that are as unique as their relationship. The journey begins with a design consultation, where couples share their vision with a goldsmith. This initial discussion helps both the designer and couple understand the direction to take the designs and what will be feasible for their budget, timeline, and personal preferences, in bringing their vision to life.

Choosing the right materials is an essential step in creating custom wedding bands. This is where mokume gane in particular is a great choice, both in quality of craft and symbolism of a strong bond.

Mokume Gane Wedding Ring Sets: A Unique Choice

Mokume gane, with its roots in traditional Japanese metal working, is a perfect style for wedding bands. This technique involves layering different metals and fusing them together, then manipulating the metals through carving and forging to create beautiful patterns. Mokume gane wedding ring sets are particularly appealing for couples seeking distinctive and artistic designs.

The creation of mokume gane rings involves fusing layers of precious metals like golds, palladium, silverand platinum. This stack of metals, called a billet, can then be twisted, folded, carved, all by hand. This painstaking process results in rings that are as unique 

The artistry behind mokume gane rings goes beyond aesthetics. The technique represents the blending of different elements—metals in this case—to form a harmonious whole. This perfectly reflects the concept of a union like a marriage, a strong bond forged to bring two people together and create something new. 

Couples can further personalize mokume gane wedding ring sets by selecting the metal combinations and patterns that resonate with their relationship. This customization allows them to create rings that are not only visually stunning but also deeply meaningful. Arn’s mokume gane work especially offers a wide variety of options, as each of his patterns has a distinct look and are inspired by different elements of nature, so the individual can choose a pattern that most reflects their personality and style. Choosing different patterns but the same metal palette is one example of a way to create a cohesive set that doesn’t feel too matching, but clearly complements each other.
