Understanding Blue Gemstones

What Are Blue Gemstones?

Blue gemstones refer to any stone that falls under the spectrum of the color blue. There are many different varieties of colors and many different kinds of gemstones - from precious gemstones to semi-precious gemstones, sparkling crystals, and cool minerals. They can be rich in color and dark and stormy as the sea or they can be pale and lucid like angel wings or even come in shades of greenish blue too. Often, blue gemstones will take their coloring from the presence of trace elements such as titanium and iron. 

Some common blue gemstones for daily wear include sapphires, aquamarines, blue topaz, and lapis lazuli, each with distinct physical and chemical properties that contribute to their appearance and their metaphysical energy. 

Historical Significance:

Looking back throughout history blue stones have played an important part. In Ancient Egypt, Lapis Lazuli was considered one of the most protective gemstones and was closely connected with the heavens. It was ground down into a beautiful blue-gold pigment and used in everything from painting to cosmetics, and in its stone form was often used in jewelry and as amulets. 

Beyond the ancient Egyptians, blue gemstones also enjoyed a period of divine popularity in the medieval ages when they became a status symbol of royalty and reality while also representing wisdom, purity, and protection.

The Hope Diamond was considered one of the most famed blue gemstones. This stunning deep blue diamond weighs 45.52 carats. Its history is shrouded in mystery and legend, with tales of curses and misfortune befalling its owners. Today, it rests in the Smithsonian Institution, drawing countless visitors each year. There's also the Blue Giant of the Orient. A massive blue sapphire weighing around 486 carats, this gemstone is notable for its rich, vivid color and immense size, making it one of the largest faceted blue sapphires in the world.

Assessing the Quality of Blue Gemstones


Blue gemstones are highly revered due to their color, and different stones will have different hues, tones, and saturations that all add to their splendor. The more impressive the color is - the higher the quality and the cost. Because there is a wide range of shades of blue, you may find that the hue varies, with some stones having purple hues and others having green. The tone is also important and speaks to the lightness or darkness of the color, and saturation is how intense the color is. Stones like sapphire are celebrated for their medium dark tone and vivid blue hue, whereas Tanzanite has a rich purple-blue hue.


All gemstones have inclusions, a natural byproduct of being born from the earth. For example, it is common to see rutile needles in sapphire stones. Inclusions can add to a gem's character and prove that the stone is real and authentic, but too many can devalue the stone as it can take away from its beauty and give it a dull appearance. 


The cut can also enhance a gemstone's brilliance. A well-cut gem will showcase its blue colors in all its beauty and play with light. Some popular choice cuts for blue gemstones include round and oval cuts that maximize sparkle. The teardrop pear is also a solid choice for those who want their blue gemstone rings to appear larger and heavier. 

Carat Weight:

The carat weight measures the heaviness of the gem rather than its size. The larger the carat weight, the higher the price usually. However, when it comes to your jewelry collection and blue stones, its worth noting that all four C's play their part. So carat is not enough if the cut color and clarity aren't good. A smaller, brighter, and well-cut stone can be worth more than something heavier but with a lesser color and clarity. 

Uses of Blue Gemstones


Blue gemstones have long been coveted in jewelry - from stunning sapphire engagement rings of our modern day to vintage Hollywood pieces and, of course - the regal splendor of crown jewels. Today, blue gemstones are also used in rings, necklaces, earrings, and bracelets and are popular with those who love ocean energy, clarity of communication, and the calm blue hues these stones bring. One of the best things about blue gemstones is the fact that you can choose from a multitude of hues - from greenish blue turquoise tales to pale topaz dreams and intense stormy sapphire - there’s a blue gem for all tastes.

Metaphysical and Healing Properties:

Blue crystals come loaded with healing properties, and often, they share attributes of being connected to calmness, communication, and easy, energetic flows. Think of ocean energy, those cool blue shades that calm hot heads and invite you to embrace change with ease. This is one of the skills of blue gemstones. Blue gemstones are also used to aid healthy and harmonious communication. They are connected to the throat chakra which means they will cleanse any blockages that are holding you back from open, honest, and clear communication. When our throat chakra is open, it means we are better equipped to convey our truth to the world, and it helps us forge closer bonds and feel understood.

Decorative Objects:

Blue gemstones can also be used in carvings and decorative objects in the home. Blue always cultivates a calm environment, and choosing blue crystal towers, pyramids, spheres, and other sacred shapes can be a great way of pulling more gentle blue energy into your home. You can place these decorative objects in areas where you want to nurture clear-hearted communication.

Caring for Blue Gemstones


If you want to keep the sparkle in your blue jewelry for centuries, then you need to give your gemstones some solid TLC and clean them. There are many methods for cleaning precious stones, but the most important thing to remember is to avoid harsh chemicals and use ultrasonic cleaners or abrasive cleaning products. A simple solution of mild soap, water, and a soft cloth will do the trick for most stones.


Preserve the precious nature of your gemstones by storing them correctly. You want to make sure that each gem is stashed in its own separate compartment, or you can store them in soft pouches to avoid gems clashing together and risking scratching each other. Also, avoid placing gemstones in direct sunlight and minimize exposure to extreme temperatures, as this could negatively impact the color of your stone.


If possible, put on your blue gemstone jewelry after using lotions, applying makeup, and other rituals, as you don't want to expose your stone to too many chemicals. You should also remove your gemstones when showering, swimming, or doing household chores that may expose your stone to knocks, scratches, and chemicals.


Gemstone enthusiasts fall hard for blue stones - whether a bright blue topaz gemstone or a gentle blue agate, radiant blue chrysocolla, a blue moonstone, or a truly impressive sparkling sapphire, each brings its own beauty and healing benefits. Known for their soothing properties, communication, and sense of peace, you can never go wrong with exploring your favorite crystal shop and adding blue gemstones as part of your crystal collection. Share with us your favorite blue gemstones, and don't be afraid to play around with adding different gem types to your growing collection.
