Custom Trends for Engagement Rings

Most people picture a diamond ring when asked to envision an engagement ring. In 2022, about 87% of buyers purchased a diamond engagement ring. However, another interesting 2022 statistic emerged: 48% of buyers customized their engagement rings to some degree.

One way to customize is to choose a primary gem like a moss agate.  

What is Moss Agate?

Moss agate is an affordable, beautiful, and sophisticated stone. The gem's body is colorless or a soft grayish/whitish color with a cloudy translucent appearance. This gives the impression of gazing into a fog. The name "moss" comes from the green branch-like inclusions which gently wind their way through the gem. Known in the trade as a "dendritic" pattern, it looks like a living plant grew inside the stone.

In this video, Jake Talve-Goodman of The Concierge Gemologist discusses the properties of moss agates and shows some amazing examples of their inclusions.

Is Moss Agate a Quartz?

Moss agate belongs to the quartz family, an expansive group of minerals. Quartz occurs all over the planet because it consists of silicon and oxygen. Both elements are amply available in the Earth's crust. Specifically, moss agate is a silicon dioxide with the chemical formula SiO2. Due to the abundance of raw materials, lapidaries can use many quartz varieties as gemstones, including moss agate. 

Many people are familiar with amethyst, a large single-crystal quartz with a purple or reddish-purple hue. However, not all varieties of quartz gems form as single crystals. Gems may also be aggregates of many small but eye-visible microcrystalline pieces or tiny cryptocrystalline quartz crystals that may only be distinguished under magnification.

What is Chalcedony?

Gemologists refer to quartz gems made of component crystals too small to see with the naked eye as chalcedony. The word chalcedony comes from a Greek word meaning "hidden," a reference to the minute size of the individual crystals that make up the gem. Not only are the individual crystals of chalcedony gems invisible to the eye, but they also feel perfectly smooth. Moss agate is one type of chalcedony.

What Gives Moss Agates Their Unique Appearance?

The green inclusions in moss agate that look so much like natural foliage are made of hornblende. During the gemstone's formation, these inclusions may become the mafic mineral chlorite. If the iron in chlorite becomes oxidized, its color changes from green to brown or red. Some moss agates may even contain dendritic inclusions that exhibit all three hues simultaneously.

Fortunately, there are no rules about which colors are most desirable in moss agate. If you want a moss agate engagement ring, pick a gem whose unique inclusions and colors most appeal to you.

Where is Moss Agate Mined?

Although you can find quartz virtually everywhere, only a few locations have experienced the proper geological conditions to produce moss agate. Perhaps the most famous deposit is located near the city of Mocha in Yemen, an ancient source of the gem. Some people still refer to moss agate as "mocha stone."

A helpful note for shoppers: vendors don't use the moniker "mocha stone" consistently. Some apply it to all moss agate, while others only use the name for gems with red or brown hues. Whenever purchasing a moss agate, always examine actual images of the stone before finalizing a purchase.

Other locations that produce moss agate include Armenia, Australia, Canada, Germany, India, northern Russia, South Africa, and the United Kingdom.

The United States boasts several dozen moss agate sources across the country. As a result, shoppers in the USA looking for a moss agate engagement ring have access to a significant amount of inventory.

What Does a Moss Agate Engagement Ring Mean?

The archeological record shows that ancient cultures have used many types of chalcedonies for jewelry and multi-purpose carvings, like amulets and talismans, for almost three thousand years. However, the lore surrounding moss agate specifically only goes back to the 18th century.

Good Luck for the Home

Thanks to the plant-like appearance of the chlorite inclusions, much of the symbolic meanings surrounding moss agate relates to a healthy ecosystem and cosmic balance. Not surprisingly, farmers favored moss agates. Perhaps they believed this gem's beautiful, organic appearance could magically help their crops grow bountifully. This association with plenty spread from farms into households. People came to believe a moss agate in the home could attract both prosperity and good luck.

Spiritual Balance

In addition to physical benefits, people believed the gem also had spiritual associations. Today, perhaps stemming from the stone's connection with a stable environment, some wearers believe it can help harmonize various aspects of their personalities and boost self-confidence.

Deeper Relationships

Some people consider moss agate a gem that promotes and strengthens friendships. On a deeper level, moss agate is also said to be connected with the heart chakra. As loving marriages are rooted in healthy and trusting friendships, some people believe wearing a moss agate engagement ring is a great way to help maintain a stable and supportive relationship with your partner. 

How Durable is a Moss Agate Engagement Ring?

Although durable enough for engagement ring use, how does moss agate compare to other more conventional engagement ring stones like diamond, ruby, and sapphire?

Like other varieties of chalcedony, moss agate has a Mohs hardness score of 6.5-7. That's a critical range. Moss agates below a hardness of 7 may accumulate scratches if not worn or stored carefully. In contrast, moss agates at a 7 or above have great resistance to scratching. (Diamond famously has a hardness of 10, and ruby and sapphire have a hardness of 9). Nevertheless, moss agate has a Wearability rating of Good.

Luckily, lighting conditions and water won't affect moss agate. However, some chemicals may harm it. This means you can wear and enjoy your moss agate engagement ring most of the time. Just remember to take it off when handling household chemicals.

Also, keep in mind that even diamond, ruby, and sapphire gemstones can chip or crack if worn carelessly and struck against a hard surface. Remove your moss agate jewelry before engaging in physical activities that could literally impact it.

Can You Wear Your Moss Agate Engagement Ring Every Day?

Moss agate is a translucent gem, and its magical beauty comes from the unique dendritic patterns the chromite inclusions make. As a result, the gem is often cut into relatively thin pieces, which allows you to see through the stone and admire those internal moss-like inclusions.

Since gem cutters emphasize surface area, not depth, when working with moss agates, finished gems tend to have thin edges, which can easily chip. If you plan to wear your moss agate engagement ring daily and have an active lifestyle, consider a protective gem setting that uses metal or other gems, or both, to protect the stone's edges.

How to Clean Moss Agate

Use a soft brush or cloth with mild, soapy water to clean your moss agate jewelry. Avoid using mechanical cleaning systems since these can shatter some inclusions and fracture your stone. Consult our gemstone jewelry care guide for more recommendations.

Remember to clean the back of your gem with as much care as the front. Your moss agate is most likely cut to let you see the inclusions, so make sure the light can shine through it. If grime accumulates behind the gem, the stone will appear darker and the inclusions more muted and difficult to distinguish. You want your moss agate garden to look as bright and wholesome as possible!

How to Buy a Moss Agate Engagement Ring

You have three major choices when purchasing a moss engagement ring: the vendor, the mounting, and the stone itself.

Where to Shop

Since moss agate engagement rings are unconventional, you likely won't find them in most brick-and-mortar stores. Fortunately, an online search will yield many options.

We recommend working with a highly rated custom jeweler like CustomMade. Their experts can help you choose the right stone for your budget and create the perfect ring for you and your sweetheart.

Choose Your Mounting

With some precautions, moss agate is strong enough to wear every day. Most importantly, protect your ring from exposure to chemicals and impacts. People with particularly active lifestyles should ask for protective settings that surround the gem's perimeter. On the other hand, if your lifestyle doesn't present a high risk of damage to your ring, you can opt for a lovely open design that features unobtrusive prong settings.

What Metal Color Goes Best with Moss Agate?

Fortunately, moss agate is a very accommodating gem that can be set in any color of jewelry metal you like. This makes it easy for anyone to find a design that flatters their skin tone and complexion.

Choose Your Stone

Every moss agate will have unique inclusions. Some may have a delicate, light green color juxtaposed against a sheer background. Other stones will feature thick and dense inclusions set against a milky body color. Some moss agates may even show oxidized inclusions with beautiful red and brown colors.

The trick to finding that perfect engagement ring is patience. Look at lots of moss agates until you find that perfect one that reaches out and grabs your attention. Some vendors recognize the very individual nature of moss agate and offer multiple gems that the purchaser can select and have mounted for comparison.

What Accent Stones Go Best with Moss Agate?

You can pair your moss agate with a wide variety of accent gems, from colorless diamonds to colorful red tourmalines, blue sapphires, green tsavorites, and more!

Moss Agate Prices

For those on a tight budget who want to purchase an unexpected and one-of-a-kind engagement ring, moss agate is a wonderful choice. The most practical boon of buying a moss agate engagement ring is the price.

In 2022, the average cost of an engagement ring hovered at about $6,000. In contrast, moss agate engagement rings have a significantly lower price point. You can easily find rings with price tags in the hundreds of dollars rather than thousands.

Much of the cost of a moss agate ring comes from the mounting itself, including the metal and labor. If you want to spend under $500, look for a silver or gold-plated metal setting. Of course, higher-quality metals, accent stones, and more intricate jewelry designs will increase prices.
