Since the beginning of time, blue gemstones have been the most sought-after jewels. We have compiled a list of the 13 best blue gemstones most commonly used in jewellery.

13 best blue gemstones used in jewellery

  1. Blue sapphire is the most popular faceted blue gemstone in jewellery because of its intense colour saturation. It gets its deep blue hue from tiny quantities of titanium and iron. Blue sapphires occur in various colours, with velvety blue to violet-blue shades being the most attractive, while greenish tints are less appealing. Heat treatment is used to increase the colour and clarity of blue sapphires. They're firm, durable stones that rate 9 on the Moh's scale of hardness and are extremely resistant to chipping and shattering, which is why they're used in so many different forms of jewellery. One of the most famous coloured gemstones for engagement rings is the blue sapphire.
  2. Blue diamonds are the rarest of all coloured diamonds because they contain a lot of boron, which gives them their blue hue. Surprisingly, these jewels have a "superdeep" origin, having developed four times deeper in the Earth than most other diamonds and being thought to have come from ancient oceans. Although they may still break when struck, they have the same characteristics as colourless diamonds and are the hardest mineral known. The saturation of these diamonds is rarely great, although they might have a vibrant hue with a tinge of grey. The Fancy Dark greyish blue hue of the renowned Hope diamond is natural. Even so, lab-created diamonds can have a blue tint. Due to the high cost of genuine blue diamonds, you may choose synthetic or treated versions instead.
  3. Turquoise is a copper mineral with a blue-green to a magnificent brilliant blue hue. It is the only gemstone having a colour named after it. It's known as 'robin's egg blue or 'sky blue' in the industry. It's usually opaque and has black vein-like inclusions, although the most expensive stones are those with no inclusions. Turquoise is commonly seen in ancient jewellery, although it may also be found in contemporary designs. Turquoise is frequently polished into cabochons and shaped into round beads for strand necklaces. If you're searching for a piece to wear every day, the stone is too soft and porous, especially on rings, bracelets, and jewellery items that are prone to abrasion or impact. It needs careful care and maintenance and should be kept away from intense heat, harming the stone's surface or producing a discolouration.
  4. Garnet is a silicate mineral with a wide range of hues. Garnet's rarest hue is blue, making it difficult for jewellers to use it in jewellery creations. Certain garnets change colour when seen under changing lighting, moving from blue-green to a deep purple tint. Blue garnets have a softness of 6.5 to 7 on the Mohs scale, which indicates they might be damaged if worn regularly. Because of its rarity, this stone is not often used in jewellery, yet it is a favourite among many jewellery collectors.
  5. Because naturally occurring blue topaz is extremely rare, most of the stones on the market have been treated to produce a blue hue that is identical to the original. The blues of enhanced gemstones can range from mild to dark and intense. While the Sky Blue type is similar to aquamarine, the Swiss Blue variation is more greenish-blue, and the London Blue has a grey tinge to it. Blue topaz is an excellent gemstone for jewellery since it has a Mohs hardness of 8 and may survive for decades. However, it is more prone to chipping since it has a perfect cleavage, which means it tends to break along its defined planes. The nicest thing about blue topazes is that they're pretty inexpensive, making them a good choice if you like blue gemstones.
  6. Aquamarine is a blue type of beryl with a lovely light blue hue that never achieves the saturation and dark tones of blue sapphires. This gemstone comes in various blue hues, ranging from greenish blue to bluish-green, with the deeper the blue, the more valuable the stone. Most aquamarines on the market have been heat-treated to remove the green tints and produce a pure light blue hue. The clarity of most faceted stones in jewellery is good, and those that are too included are typically cut, polished into cabochons, or fashioned into beads. Aquamarine is a firm stone that scores 7.5 to 8 on the Mohs scale of hardness, making it suitable for everyday use. It's also less likely to shatter. However, excessive heat should be avoided.
  7. Tanzanite is one of the world's rarest jewels, discovered exclusively in the African nation of Tanzania, making it a symbol of the country's heritage and rich history. Because the crystal is brownish in its natural form, most blue versions on the market have been heat-treated. The blue tanzanite unearthed by Maasai tribesmen is the sole exception, as it was most likely exposed to a natural heat source within the Earth at some time. Tanzanite's colour ranges from light blue to deep blue and violet colours, resembling exquisite sapphire for a fraction of the cost. It is the second most common blue gemstone in the United States, behind sapphire. Tanzanite has a Mohs hardness of just 6-6.4, which indicates that if it is struck against a hard surface, it will readily break or chip. As a result, it's commonly seen as earrings, necklaces, and pins. It should be set in a protective setting when used in a bracelet or ring to prevent it from being damaged.
  8. Blue opal- There are many different kinds of opals, and not all of them have the multicoloured flashes known as "play-of-colour." The Peruvian opal is a common opal discovered in Peru, and it comes in a variety of colours ranging from light to dark pastel blue. The shimmering hues of precious opals resemble the sunshine on the ocean's surface. Black opal is a gemstone that has a dark blue, dark grey, or dark green colour. Blue opal is a delicate stone with a Mohs hardness of 5 to 6.5, making it readily scratched and broken. However, it’s still a beautiful stone for earrings, pendants, and brooches. When it comes to rings, choose a protective setting such as bezel versus prong, which exposes the diamond to impact. Your opal jewellery will last a long time if you take proper care of it.
  9. The majority of blue tourmaline has a greenish tinge, with tones ranging from mild to dark. Its blue hues can be bright or muted, and grey, but pure blue stones are highly prized. The deep violet-blue hue of tourmaline rivals that of the best sapphires. Many blue tourmalines are heat-treated and include traces of iron that give them their hue. The Paraiba tourmaline, which is highly coveted for its beautiful neon blue and blue-green hues, is one of the rarest kinds of blue tourmaline. Tourmalines are extremely hard (Mohs scale: 7-7.5) and may last a lifetime if properly cared for. Although blue tourmaline in jewellery is uncommon, it is possible to obtain tiny stones under a carat in modest sizes. However, because of the stone's scarcity, prices might reach several hundred dollars per carat.
  10. Blue zircon is one of the most dazzling gemstones on the planet, and it resembles a blue diamond in appearance and brightness. The most common zircon colour is blue, which comes in various hues ranging from light pastel blue to dark vibrant blue. Stones with intense saturation are highly uncommon and valuable. The hardness of blue zircon ranges from 6 to 7.5 on the Mohs scale. Because it is a fragile stone that can be broken or worn down over time, it should be put in a protective context. The birthstone for December is blue zircon.
  11. Blue spinel- For decades, spinel was mistaken for sapphires, earning it the moniker "the great impostor of the jewellery industry." Spinel is a magnesium aluminate mineral that may be found in the same mines as corundum. When professionally cut, most blue spinel is eye-clean and displays brilliance and fire. Although spinel is a rare gemstone equivalent in durability and beauty to sapphires, it is less expensive and may be purchased at reasonable rates. Even though it has been synthesised, spinel is never processed or heated. Spinel is a hard gemstone that scores eight on the Mohs scale and is suitable for everyday use.
  12. Lapis lazuli comprises multiple layers of minerals such as lazurite, calcite, and pyrite and is recognised for its distinctive, cosmic look. The stone's stunning blue hue is caused by lazurite grains, while the golden, metallic-looking specks are caused by pyrite. The golden pyrite flakes aren't always visible, although white calcite streaks can be seen. This stone's hue ranges from dark blue to greenish and violet-blue, and it's been dubbed royal, midnight, and sea blue by some. The most valuable Lapis is referred to as "Afghan" in the trade, and it has a vivid, somewhat violet-blue hue with little or no pyrite and calcite. These stones are frequently fashioned into beads, cabochons, sculptures, and inlays. Lapis lazuli is a beautiful gemstone for jewellery, but it is prone to scratching and isn't suitable for everyday use. The best part is that jewellery created from this stone is relatively inexpensive, and it may endure for decades with proper maintenance.
  13. Lolite is a kind of cordierite mineral that is frequently confused for more valuable tanzanite or sapphire. It comes in various blue hues, from light to vibrant, but saturated violet-blue is the most popular. Iolite is historically significant since it is said to be the sunstone utilised by Vikings for maritime navigation. Iolite is a mineral with a hardness of 7 to 7.5 on the Mohs scale; however, it is not highly durable due to its pronounced cleavage, which can cause the stone to shatter if struck hard. Despite its beauty and amazing hue, the stone isn't highly valued because it's abundant in nature. If you're looking for a blue gemstone on a budget, iolite is a beautiful and affordable alternative to more expensive stones like sapphires.
