The Increasing Allure of Teal Sapphire Engagement Rings

What is a Teal Sapphire, and how is it different from the traditional rich blue colored Sapphire? Read on to learn about the origin and uses of these beautiful gemstones in engagement rings.

The ever-popular Teal sapphire, also known as Montana sapphire or mermaid sapphire, is most used in nature-inspired settings due to its deep ocean blue and vivacious green hues.  These ethereal stones can present as a unique combination of blue green, teal, gray, and even aqua. The teal sapphire stone blends seamlessly with 14k rose gold, white gold, and platinum, and their beauty, durability, and affordability make them the perfect center stone for any piece of jewelry.

 This article will give you inspiration to use this type of sapphire in an engagement ring and show you some of our favorite blue-green sapphire engagement rings.

Why is it called Montana Sapphire?

Montana Sapphires are the first gem-quality sapphires found in the United States in 1865 by early gold prospectors and are one of the reasons for Montana’s nickname, “The Treasure State.” They are unique to the state of Montana and are commercially mined in the state. They are found in a wide variety of colors – the most well-known being teal, blue/green, and blue-gray, and green-blue. Most Montana sapphires have a distinct pale color that distinguishes them from the more vibrant and darker blue sapphires that most people are familiar with.

What is a Mermaid Sapphire?

Due to their teal, blue/green color, Montana sapphires are sometimes referred to as mermaid sapphires. They are often used in nature-inspired designs because of their rich greens and blue-green hues and are commonly found on Pinterest and Etsy.


Are Montana Sapphires Good for Engagement Rings?

Yes. Not only are they beautiful, but Montana sapphires (like all sapphires) are 9 out of 10 on the Mohs Hardness Scale used by jewelers and gemologists alike. They are one of the most durable options for jewelry, coming in third behind diamonds and moissanite. They’re also conflict-free because they’re ethically mined in the United States. These factors combined with their stunning hues make them a great option for an engagement or wedding ring. 

Here are some of our favorite teal sapphire rings we’ve custom-designed for our clients:

The JenniferThe Jennifer Montana Sapphire engagement ring custom made by Abby Sparks Jewelry.

Set in 14k rose gold, The Jennifer, a custom-designed engagement ring is a light green sapphire cluster engagement ring using a 3-carat light green trillion cut sapphire as a center stone. Diamonds, sapphires, and tourmaline stones are scattered around this main focal point in an asymmetric pattern, adding a variety of bold hues.  The diamond clusters on either side reduce significantly in size in order to allow the sapphire maximum attention.

The Sass

The Sass is a unique cluster engagement ring custom designed for a preschool teacher who loves the aqua-blue color the ocean and features a diagonally set pear cut Montana sapphire as the main focus. All of these ethically sourced stones are set low profile and close to the finger in white gold for comfort and durability for our client’s busy day-to-day activities as a preschool teacher.


The Megan

Our client loved the design of asymmetrical engagement rings, so we created a stunning sapphire cluster ring named The Megan for her. This light, greenish-blue oval sapphire is surrounded by champagne, gray, and white diamonds, along with some smaller sapphires which add special sparkle to the cluster without distracting from the star of the ring – the oval sapphire center stone. The band is platinum for a shiny finish that keeps an overall cool tone.

The Amelia

The Amelia sapphire clustered halo ring was designed for our client who is an artist and works in public health advocacy. She wanted something totally unique that didn’t look like other rings she had seen before. Using a pear cut teal blue sapphire as a center stone, we created an asymmetric mirrored design on each side of the center stone. Six pear cut and round cut sapphires set at North and South are rimmed in milgrain (an extremely tiny beaded detail that finishes an edge on a piece of jewelry) to frame and anchor the design. The side stones, featuring sapphires in various hues, then taper off into a subtle cluster design. The whole design is set in warm, 14k rose gold.

The Stephanie

The Stephanie teal sapphire and emerald cluster ring was created for our client who wanted a beautiful cluster ring with beautiful hues of blues and greens. We sourced a deep teal Montana sapphire in pear cut as a center stone. Set at a tilt, the rest of the stones cluster around the sapphire to create a unique, organic design. We used an array of emeralds, blue sapphires, and diamonds in various shades to create the constellation of colors our client had envisioned. The cool tones are contrasted against warm, 14k rose gold.

The Laura

Emerald cut teal sapphire engagement ring made for Laura by Abby Sparks Jewelry

This teal sapphire engagement ring was designed with a very specific color in mind. We sourced this perfect teal, 4-carat elongated emerald cut sapphire as the center stone and inspiration for the rest of Laura’s piece. Clustered around the center stone are diamonds and sapphires in various shapes and colors, giving this piece a very organic and unique look. The clusters are bezel set, with milgrain detailing around each stone. A 14k yellow gold band creates contrast, bringing out the teal color of the center stone.

The Lindsey

The Lindsey was created for our client who wanted a durable ring she could wear every day. She loved the idea of a disc with a cluster of diamonds and wanted something simple and dainty with organic shapes. Because she loves the light green stones, Montana sapphires were the perfect stone choice for her ring which is set in yellow gold in a cluster setting and surrounded by diamonds and sapphires.
