Blue gemstones have always been an excellent choice in jewelry because they match a variety of fashions, are never out of fashion and can be used for a variety of occasions. You are stress-free when you have light blue gemstone jewelry or dark blue gemstone jewelry. Whatever your preference, we are here to introduce you to various types of blue gemstones from the world over.
Best Known Marine Blue Color Gemstones
Undoubtedly, sapphire is the most legendary of all the blue gemstones. It’s rare, with dazzling clarity and brilliance, and is just as expensive as rubies and diamonds. Blue sapphire is often paired with colorless diamonds on wedding rings and engagement rings. The most beautiful quality sapphires have a deep and rich color saturation that makes you feel like you are swimming in blue. It is the gemstone for the fifth wedding anniversary as well.
Sapphire is one of the most robust gems around because it rakes in a nine on the Mohs scale of hardness. A single carat of this precious stone can fetch a minimum of $500 to $5,000. It is durable and highly scratch-resistant, and many say that even diamond can’t break a blue sapphire.
Amazonite holds the distinction of having a distinctive blue-green shade that can be compared to aquamarine. Take note that “amazonite” is a registered trade name for a class of gem-quality feldspar. The feldspar family includes jasper as well. The greenish overcast in amazonite is said to be caused by the presence of small quantities of lead in the chemical structure of the gemstone.
This precious stone has been in human use for over 2000 years now, but it is not as popular as the other stones, so it may be difficult for you to find it in department stores and small jewelry stores. However, you may have hope in gem shops where gemstones are sold for energy healing and crystal practices.
Agate is a subtype of chalcedony that features a host of colors, from blue to orange. All agate are subtypes of microcrystalline quartz. “Chalcedony” is another name for quartz with differing microcrystalline structures, just so there is no confusion.
Aqua agate is a banded type of chalcedony with similar shades of blue and green comparable to amazonite. Like another banded chalcedony, this gem has a focal point where concentric layers of various colors emanate from.
Agate is well-known for having an eclectic mix of patterns in individual samples, so it’s not surprising that even the aqua agate variant shows great diversity if you observe the color patterns across the samples or specimens. Note that not all aqua gate has deep color saturation – others have very light saturation that may even make them look like light green jade.
Apatite is a class of phosphate mineral that is used not just for jewelry but also for agricultural applications. Apatite contains phosphates that are necessary for fertilizing agricultural land. It is not a very durable stone because it scores only a five on the Mohs scale of hardness. Nonetheless, the specimens that have the best color saturation and clarity are taken to cut and polish for jewelry and other ornamental applications.
Blue apatite is often cut into cabochons to maximize beauty when set on rings and other types of jewelry.
Benitoite is a rare type of gem that also happens to be the official gemstone of California. Benitoite was first formally descended in 1911, and it naturally occurs as a blue gem with high brilliance and clarity.
This gem is said to have been the product of hydrothermal metamorphism. Visually, benitoite is a natural simulant of sapphire, and untrained eyes will likely mistake this gem for sapphire because it looks so good. However, some necessary tests like density and hardness will reveal which is which.
Aquamarine is a highly transparent glass of mineral that often occurs in nature as large crystals. Aquamarine has either a resinous or vitreous luster, and due to its abundance, it is one of the more affordable blue gems in this countdown. You can purchase a carat of aquamarine for just $10.
The higher quality aquamarine cuts will fetch around $500/carat, depending on the type of jewelry that you buy. Aquamarine is often set in jewelry rings, but this doesn’t mean that they won’t look good on pendants, general daily wear rings, and bracelets.
Howlite is a borosilicate mineral that was first discovered in Nova Scotia in 1868. It occurs in nature as either transparent or translucent, and it features opaque mattings of webs throughout. It may also have more beautiful veins that are either grey or black, depending on the sample.
Lapis lazuli is a magnificent stone that has multiple uses, from ornamental wares to pigments. It is still used today as a pigment for students of traditional art. Inclusions in lapis lazuli include a variety of minerals like calcite, which produces white veins and matting patterns, and pyrite, which occurs in lower levels but forms noticeable granular flecks of gold-colored mineralization.
The moonstone is a fascinating gemstone with a schiller effect called adularescence. Adularescence refers to the faint glow that comes from within the moonstone that reminds people of moonlight when the skies are clear. This effect is the result of light diffracting and bending inside the moonstone because of multiple minerals’ layering.
Turquoise is a hydrous phosphate mineral with a most amazing blue-green color. Its color is in a class of its own. The deeper, bluish-green turquoise stones are considered high-value and are much more desirable than specimens with yellowish hues or have lighter blue tones.
Zircon is a mineral comprised chiefly of the element zirconium. It is found mainly in metamorphic or igneous rock hosts. It has been in recorded human history for over two thousand years, and it has a brightness and fire that rivals the best-cut diamonds. Cubic zirconium is often used as a high-level natural simulant of the diamond.
Because of its opaque look and unique color quality, Smithsonite is also called “turkey fat,” which is one of the unique names ever in gemology. It is a type of zinc carbonate that was first described in the early 1800s. It has either a pearly or vitreous luster, and it has a trigonal crystal system with a Mohs scale ranking of four to 4.5.
