Shades of Blue

Despite being a relatively rare color in nature – reds, browns, greens, and yellows are much more common – blue comes in an entire spectrum of brilliance, from the lightest sky blue and gentle baby blue to bright azure and ultramarine to dark navy or midnight blue. This broad gradient includes shades such as cornflower, cobalt, turquoise, denim, cyan, indigo, cerulean, and much more.  

Some shades of blue are named for their geography, such as Prussian, Persian, or Pacific blue, while others are named for sports teams or other affiliations, such as Air Force, Carolina, Dodger, or Tiffany blue.

Blue is a generally cool color and may have green, purple, or grayish undertones that give even more distinction to particular shades. With such great variety in the overall color, there can be beautiful blue gemstones to suit anyone’s jewelry preferences.


The most popular blue gemstone is the precious gem sapphire, the September birthstone known for its rich, royal hues. The lighter, watery shades of aquamarine, the fiery sparkle of blue diamond, and the blue-green luster of turquoise are also popular blue gemstone choices. Tanzanite is known for its purple-blue hues, while the clarity of blue topaz gives it extra glitter. Other top gemstones that have stunning blue shades include moonstone, opal, pearls, spinel and zircon.

The exact shade of blue varies for each gemstone, and different types of gems all have their own range of blue hues they may exhibit. This creates great variety for blue gemstones. While some of these gems are more difficult to find than others, each one offers great options for stunning blue jewelry.

5 Most Popular Blue Gemstones

• Sapphire

Sapphire, renowned for their stunning beauty and durability, are a highly prized gemstone available in a variety of colors, with blue being the most iconic. Sapphires are often used in engagement rings as symbols of loyalty, faithfulness, and sincerity. Their enduring quality reflects the commitment of a lasting relationship.



• Aquamarine

Aquamarine, known for its stunning blue to blue-green hues, is a captivating gemstone that evokes the tranquility of the sea. This variety of beryl has a Mohs hardness of 7.5 to 8, making it durable enough for everyday wear while retaining a brilliant clarity and sparkle. Highly valued for its serene and calming properties, aquamarine symbolizes courage and inner strength, making it a popular choice for engagement rings and various other jewelry pieces.

• Blue Zircon

Blue zircon is a captivating gemstone known for its brilliant blue color and exceptional fire, often rivaling that of diamonds. With a Mohs hardness of 6.5 to 7.5, it is relatively durable, though it requires careful handling to prevent scratches and damage. Blue zircon is believed to promote wisdom, honor, and spiritual growth, making it a popular choice for those seeking a meaningful and beautiful stone.

• Opal 

Opal is a mesmerizing gemstone renowned for its unique play-of-color, displaying a spectrum of vibrant hues that seem to dance across its surface. This phenomenon, caused by the diffraction of light through its microstructure, makes each opal unique and captivating. Opal can exhibit blue colors as part of its unique play-of-color. This optical phenomenon occurs due to the diffraction of light within the gemstone's internal structure, which consists of microscopic silica spheres

Blue Symbolism

But why do we love blue so much? The answer may vary depending on one’s culture, faith, and personal preferences.

• Meaning & Symbolism

The color blue has a wide range of symbolic meanings. In general, blue is considered a calming, peaceful, relaxing shade. It is often associated with conservatism and steadfastness, as well as loyalty and integrity. Deeper blue shades evoke authority, while lighter shades have a delicateness that can symbolize fragility. Hope, healing, determination, grace, and emotional depth are all symbolic meanings connected to the color blue. In some cultures, blue is a sacred color associated with paradise, and can be protective against the evil eye. 

Official symbolism of the color blue is likewise widespread. More than 50 percent of the national flags in the world feature at least some blue in their design, and blue is a popular color for sports teams, corporate logos, and schools.

• Birthstones

Certain blue gemstones are also official birthstones – sapphire is the September birthstone, aquamarine is the March birthstone, and five blue gems – blue zircon, blue topaz, tanzanite, turquoise, and lapis lazuli – have been named as December birthstones. Different blue gems are also official wedding anniversary gemstones – blue topaz for the fourth anniversary, sapphire for the fifth, and lapis lazuli for the ninth. Even more blue gems are connected to higher anniversary years: aquamarine (19), iolite (21), spinel (22), tanzanite (24), sapphire (45), and sapphire again (65). 

With so much symbolism, there are many reasons to choose a blue gemstone, no matter what you may want it to represent.

Meghan Markle, the Duchess of Sussex, wore Princess Diana's aquamarine ring to her wedding reception in 2018. This ring has a deep personal significance and showcases a stunning emerald-cut aquamarine stone.

The Marie Louis Diadem is yet another outstanding example of royal blue gemstones, but this exquisite piece features 79 Persian turquoise stones. Once belonging to Marie Louise of Austria, second wife of Emperor Napoleon of France, the diadem frames its signature cabochon turquoise stones with meticulous scrollwork and delicate filigree in floral motifs.
