Understanding Blue Gemstones: Formation, Varieties, and Quality

Blue gemstones are minerals which showcase a blue color, whether they form in nature or in a lab. They get their blue color when infinitesimal elements inside the stone interact with the light. Although, their structure and the way of passing light through them also affect their color.  In simple terms, these stones absorb some colors of light and reflect the blue color that you usually see.

Different elements produce different shades of these blue gemstones. Such as iron and titanium give sapphire a deep blue color. While copper gives turquoise a blue color. Each gemstone integrates these elements in its own way, that gives it a unique and beautiful color.

Some gemstones appear through light scatter and this phenomenon is called the Tyndall effect rather than from any single element. Moonstone’s blue adularescene, a floating allure that shifts with viewing angle, in one example of the structural color rather than chemical color.

Types of blue gemstones:

A deep guide below about types of blue gemstones covers each and everything need collectors know:

Precious blue gemstones:

The term “precious” in the gemstone trade traditionally refers to diamond, ruby, sapphire, and emerald. Two of these blue sapphire and blue diamond sit at the blue gemstone hierarchy.

• Blue Sapphire is the defining precious blue gem. It is a variety of corundum (aluminum oxide), it registers 9 on the Mohs scale of hardness which makes it the second hardest natural gemstone after diamond. Its color ranges from pale cornflower blue to the deep royal blue and intense velvety blue. The most valued shade is medium dark, vivid blue with having slight violet, which is often called Kashmiri blue or Royal blue. Sapphires from Kashmir, Burma (Myanmar), and SriLanka command the highest prices. Most commercial sapphires undergo heat treatment to improve color and clarity, a widely accepted practices in the trade. 
• Blue Diamond is among the rarest and most expensive gemstones on the earth. The blue color results from boron impurities within the crystal structure. Since, natural blue diamonds at gem quality are extraordinarily scarce; most come from the Cullinan mine in South Africa. Whether Lab grown blue diamonds exist and offer a same chemical composition at a fraction of the price.
• Tanzanite is sometimes grouped with precious stones due to its exceptional color and rarity. It is found only near Mount Kilimanjaro in Tanzania, it displays a striking blue violet  trichroism appears different colors hinge on the viewing angle. It scores 6 to 7 on the Mohs scale of hardness, which makes it softer than sapphire, and geologists that consider it approximately 1,000 times rather than diamond. Current reserves are expected to be exhausted within decades.

Semi precious blue gemstones:

Semi previous blue gemstones are a broad old fashioned term that covers the most colored stones that except diamond, sapphire, ruby, sapphire, and emerald. Many of them are still beautiful and durable, even if they are not precious.

• Aquamarine is a blue to blue-green type of beryl. It gets its name from “Sea water” and ranges from pale sky blue to rich medium blue. Since top stones are pure blue without having green color. Aquamarine is quite hard ranks 7.5-8 on the mosh scale of hardness, means good for everyday wear, and mostly it is slightly heat treated to remove green tones. Brazil is the major source.
• Blue topaz is the most popular and affordable gemstone. Natural topaz is generally colorless or pale; almost all blue topaz stones are treated with irradiation and heat to create shades like 8 on the mohs scale of hardness means great for daily wear jewelry like ring, and bracelet.
• Turquoise is basically recognized as the oldest gemstone. It is a hydrated copper aluminum phosphate with a waxy shine and colors from sky blue to blue-green. The best turquoise is a clean, pure robin’s egg blue with little or no brown veining. It is porous and soft ranks 5-6 on mohs scale.
• Lapis lazuli is a rock and Lazurite mineral makes it with white calcite and shiny gold pyrite specks that look like a night sky. It has been used for thousands of years, even as a blue paint pigment. It is moderately soft and ranks 5-6 on Mohs scale, so it works best in earring, pendant, or protective setting rather than heavy use ring.
• Moonstone showcases a soft, floating blue glow called “adularescene,” that is caused by thin layers of feldspar that scatter light. The best stones have a strong blue sheen on nearly colorless base. It is slightly softer and ranks 6-6.5 on mohs scale and a bit fragile.
• Iolite which is also called water sapphire or Viking compass stone looks blue one direction but can appear yellow or almost colorless when it is turned. It is an affordable alternative to sapphire and is fairly hard ranks 7-7.5 on mohs.
• Blue kyanite is a striking blue mineral with having long, blade-like crystals. It has unusual hardness; softer along the 4.5-5 but harder across the width like 6.5-7. It is still an under appreciated and uncommon gem.
• Zircon is natural mineral with having very high sparkle, sometimes close to diamond. Blue zircon is a brilliant popular gem that showcases a bright, electric blue color.

Rare blue gemstones:

There are several blue gemstones are so rare which collectors generally see them only in specialist markets, not in everyday jewelry stores.

Under shortwave UV light, it grows brightly, and its vivid blue color holds strong fire and sparkle. Benitoite serves as California’s state gem and commands high prices because of its scarcity and beauty.
• Blue grandidierite is a teal to blue-green gem comes from Madagascar that only recently entered the gem collector scene. Transparent, clean stones are extremely hard to find, and the gem showcases strong trichroism, which means it can shift between different blue and green tones as you turn it.
• Jeremejetive counts among the rarest minerals on Earth. When it forms gem quality crystals, they usually show up pale blue or nearly colorless and mostly attract mineral collectors rather than mass market buyers.
• Hauyne is a deep blue mineral that belongs to the sodalite group, found majorly in Germany and Morocco. Since, hauyne stones rarely appear outside private collections, because gem quality material is  scarce and difficult to work.
• Paraíba tourmaline, is a special variety of tourmaline, that produces an electric neon blue to green color we are grateful to copper and manganese in its crystal structure. You can find it in Brazil, Nigeria, and Mozambique, but faceted stones of top quality rank among the most expensive gems per carat in the world.

Blue gemstone colors and variations:

Blue gemstones cover almost the entire visible blue range, and use clear color terms can help buyers to describe what they want and evaluate stones more effectively.

• Sky blue gemstones showcase a pure, medium strength  blue without strong violet or green undertones. Whether Swiss blue topaz and some aquamarines of ten fall into this category, and their balanced shades remain the most popular and universally flattering colors in the market.
• Royal blue and deep blue introduce the classic sapphire look as like a rich, saturated, medium dark blue color that feels intense but not black.
• Navy blue gemstones lean toward very dark with having slightly lower saturation. London blue topaz fits this group, as do the similar darker sapphires and dark blue tourmalines. These deeper blues suit men’s jewelry and bold, statement that makes designs.
• Blue-green gemstones live in the space in between blue and teal. Although, Paraíba tourmaline, grandidierite, some aquamarines, and turquoise all showcase this blended color.

Are blue gemstones valuable?

Yes blue gemstones are among the most expensive substances on the earth to some of the most affordable gems in commerce. Value hinges almost entirely on the specific stone, its quality, and treatment status.

Pricing factors:

Five key factors that determine the values of any blue gemstones:

1. Color  is the most crucial factor. In colored gemstones, color accounts for roughly from 50 to 80% of value. The ideal color is typically a vivid, pure, well saturated blue without gray, brown, or expensive violet masking. Hue, tone, and saturation all matter a washed out blue or an overly dark blue both reduce value as compared to the ideal.
2. Clarity matters differently across stone types. In sapphires and aquamarines, fine inclusions significantly reduce value. Whether in turquois and Lapis Lazuli, which are opaque blue nature, clarity in the traditional sense doesn’t apply instead, of the quality and evenness of color and matrix pattern drive value.
3. Carat weight affects price per carat dramatically. A 3 carat of blue sapphire is equal quality to a 1carat stone that doesn’t cost three times as much it costs exponentially more, because larger clean sapphires are far rarer.
4. Treatment status has major pricing implications. Since, natural, untreated gemstones hold premium prices over treated stones. Although, heat treated sapphire of identical appearance to an unheated one can cost 30 to 200% less. Certification from a respected gemological laboratory that confirms “not heat” treatment adds substantial value.
5. Origin adds a premium for certain sources. Since, Kashmir sapphire, Burmese ruby, Colombian emerald, and  Paraíba tourmalines from Brazil all command origin premiums due to historical reputation and quality associations. An origin certificate from a recognized lab is required for these premiums to apply.

The connections are deeply related to the metaphysical and spiritual traditions. They are symbol and cultural, but can’t be substituted for medical advice or treatment.

How to identify realistic blue gemstones:

Many practical tests and indicators can help buyers to differentiate between natural blue gemstones and synthetic lab created means heat treated gemstones:

Temperature test:

Natural blue gemstones, are mineral crystals, which make you feel noticeably cool to the touch at room temperature. Since, glass and plastic imitations warm up quickly in the hand. Whether a realistic sapphire or aquamarine hold against the cheek will feel distinctly cool. This is a first pass indicator, not a definitive test.

Hardness test:

Recognizing the Mohs scale of a stone can help to confirm identity. Sapphire is 9 can’t be scratched by knife blade owns around 5-5.5 or a glass plate 5.5; blue glass imitations can be. So the test must only be performed on areas of unset stones.

Inclusions under magnification:

Natural gemstones normally showcase tiny inclusions, like crystals, healed fractures, rulite needles in sapphires, or growth tubes in Aquamarine. Whether synthetic stones often look too clean or showcase curved growth lines under magnification. Imitation glass typically has curved bubbles.

Dichroism:

Several blue gemstones are pleochroic because they showcase vary colors in different viewing directions. Although, Aquamarine displays blue and near colorless. A simple dichroscope discloses this immediately. Glass and most imitations show no pleochroism.

Specific gravity:

Each mineral owns a characteristic density.  A stone that seems unusually light for its size can be named by glass or synthetic. If we take an example of sapphire which has specific gravity of around 4.0 glassy typically runs 2.6 to 3.5.

UV fluorescence:

Some of the stones fluoresce characteristically under ultraviolet light. Whether many other Sri Lankan sapphires showcase orange to red fluorescence under longwave UV. Synthetic sapphires and natural sapphires from other origins often don’t. Whether Aquamarine can show weak blue to green fluorescence.  Blue topaz is typically inter under UV.

Certification:

For any significant purchase, always request for a laboratory certificate from a recognized gemological laboratory like GIA, Gübelin, SSEF, GRS, or AGL.

Although, these labs test specific gravity, refractive index, spectroscopic absorption, and microscopic inclusions characteristics to confirm identity, origin, and treatment status. No other method comes close to lab certification in reliability.

Blue goldstone:  

deserves a specific note, it is usually a man made glass with having embedded copper crystals that create a sparkly, deep blue appearance.

It is not a natural mineral or gemstone. It is sometimes sold without clear disclosure. Genuine natural blue gems don’t contain a regular lattice of metallic glitter that characteristic appearance is unique to gold-stone.
