Amber Gemstone Guide

Amber at a Glance

How Amber Forms

Amber begins as sticky resin produced by ancient trees. When this resin was buried beneath layers of sediment, it underwent chemical changes over millions of years. Through a process called polymerisation, the volatile compounds within the resin evaporated and the remaining material hardened and fossilised, eventually becoming the amber we recognise today.

The transformation from fresh resin to true amber requires immense geological time and specific environmental conditions. This lengthy process distinguishes amber from younger, less mature resins such as copal.

Colour and Appearance

Amber displays a beautiful range of warm hues. The most familiar colours include pale yellow, honey, golden, orange, and reddish-brown through to deeper brown tones. Some amber may appear white or milky, whilst rarer examples can show greenish or even blue coloration under certain lighting conditions.

The material may be transparent, translucent, or opaque. Many pieces contain internal structures such as flow lines, bubbles, or organic inclusions. These natural features contribute to amber's unique character and visual appeal.

Inclusions in Amber

One of amber's most remarkable qualities is its ability to preserve ancient plant material, insects, and other small organisms. These inclusions offer a fascinating glimpse into prehistoric ecosystems and can make certain pieces particularly interesting.

Durability and Suitability for Jewellery

Amber's Mohs hardness of approximately 2–2.5 makes it considerably softer than most mineral gemstones. This means amber is vulnerable to scratching and should be handled with care. It also has relatively poor toughness, making it susceptible to chipping, cracking, or breaking if dropped or struck.

Despite these limitations, amber is well suited to jewellery types that experience less daily wear and impact:

• Earrings
• Necklaces
• Pendants
• Bracelets
• Beads
• Rings (when worn with additional care)

One advantage of amber is its very low density, which means even larger pieces remain relatively lightweight and comfortable to wear.

Where Amber is Found

Amber deposits occur in various locations around the world. Recognised sources include the Baltic region, the Dominican Republic, and Myanmar, amongst others. Each deposit can produce amber with different ages, colours, and characteristics.

Geographic origin alone does not determine quality. Amber from different sources may vary in appearance and properties, but desirability ultimately depends on the individual piece's colour, clarity, inclusions, and overall condition.

Baltic Amber

Baltic amber has a long and distinguished history of use in European jewellery and decorative objects. Sourced primarily from countries surrounding the Baltic Sea, this material has been prized for centuries and remains one of the most recognised types of amber in the jewellery trade.

Assessing Amber Quality

When evaluating amber, customers may consider several factors:

• Colour: The hue and saturation of the material
• Transparency or opacity: Whether the amber is clear, translucent, or opaque
• Clarity: The presence or absence of internal features
• Inclusions: Type, rarity, condition, and overall quality of any preserved organisms or plant material
• Cut and polish: The quality of shaping and surface finish
• Size: The dimensions and weight of the piece
• Surface condition: Freedom from cracks, chips, or damage
• Treatments: Whether the amber has been heated, pressed, or otherwise altered
• Overall visual appearance: The combined aesthetic appeal

It is important to note that inclusions do not always increase value. Desirability depends on the type, rarity, condition, and quality of the inclusion, as well as the overall appearance of the piece.

Natural, Treated and Pressed Amber

Natural amber may be heated or otherwise treated to alter its colour or clarity. Such treatments can enhance the material's appearance or create certain visual effects.

Some amber may be pressed or reconstructed from smaller pieces using heat and pressure. This process creates a solid material from fragments that might otherwise be too small for jewellery use. Dyes may also be applied to create or enhance certain colours.

Treated or pressed amber should be accurately represented and disclosed where relevant, allowing customers to make informed purchasing decisions.

Amber vs Copal

Copal is younger resin that has not undergone the same degree of fossilisation as true amber. Whilst amber and copal may appear similar, they differ in age, chemical composition, and maturity.

Copal is softer and less stable than amber, and may be more susceptible to damage or deterioration over time. Understanding the distinction between amber and copal is important when assessing authenticity and long-term durability.

Amber Imitations

Glass, plastic, resin, and other manufactured materials may be used to imitate amber. These imitations can sometimes be convincing, particularly to the untrained eye.

Simple home tests are not always reliable and may damage jewellery. For valuable pieces where identification matters, assessment by a qualified gemologist or gemological laboratory is recommended.

Caring for Amber Jewellery

Amber Meaning and Symbolism

Throughout history, amber has been associated with warmth, protection, sunlight, and good fortune. These associations reflect cultural traditions and historical beliefs rather than proven effects.

Amber's warm golden tones and ancient origins have made it a valued material in jewellery and decorative arts for thousands of years. Today, it continues to be appreciated for its natural beauty, unique character, and connection to the distant past.
