Citrine: Meaning, Colour, Properties & Jewellery Guide

What Is Citrine?

Citrine is a yellow to orange variety of quartz, one of the most abundant minerals in the Earth's crust. Its warm, sunny colour has made it a popular choice for jewellery for centuries, valued for both its beauty and its durability.

As a member of the quartz family, citrine shares the same chemical composition as amethyst, rose quartz and smoky quartz, but it is the presence of iron within the crystal structure that gives citrine its distinctive golden hues.

Citrine Colour

The colour of citrine is its most defining characteristic. Citrine gemstones range from pale, delicate lemon-yellow through to rich golden yellow, warm orange and deep brownish-orange tones sometimes referred to as Madeira citrine.

This colour is caused by iron-related changes within the quartz crystal structure. The intensity and exact shade depend on the concentration and distribution of iron, as well as any natural or applied heat treatment.

Natural and Treated Citrine

Naturally occurring citrine exists but is relatively uncommon in nature. Much of the citrine available in the jewellery trade today is produced by heat-treating amethyst or smoky quartz, both of which are also varieties of quartz.

When certain types of amethyst are heated to controlled temperatures, the purple colour transforms into the warm yellow and orange tones characteristic of citrine. This process is stable and permanent, and the resulting gemstone is still genuine quartz.

Heat-treated citrine is widely accepted in the jewellery industry, though treatment should be accurately described and disclosed where relevant. Both natural and treated citrine are valued for their beauty and durability.

Citrine Durability

Citrine has a Mohs hardness of 7, making it a durable gemstone suitable for many types of jewellery, including rings, earrings, necklaces, pendants and bracelets. This hardness means citrine is resistant to scratching from everyday wear, though it is not indestructible.

Like all gemstones, citrine benefits from sensible care. Avoid hard impacts, sudden temperature changes and prolonged exposure to harsh chemicals to keep your citrine jewellery looking its best.

Where Is Citrine Found?

Citrine is found in several locations around the world. Recognised sources include Brazil, Bolivia, Madagascar, Zambia and other producing regions. Brazil is particularly well known for its citrine production, both natural and heat-treated.

It is important to note that origin alone does not determine gemstone quality. Citrine from any location can vary in colour, clarity and overall appearance, and quality should be assessed on the individual characteristics of each stone.

Citrine Quality Factors

Several factors influence the quality and value of citrine gemstones:

• Colour: The most important factor. Vivid, saturated colours are generally preferred, though personal taste plays a significant role.
• Clarity: Citrine commonly occurs with good transparency and clarity, though natural inclusions can still be present.
• Cut: A well-executed cut maximises brilliance and colour.
• Carat weight: Larger citrine gemstones are readily available, making size less of a rarity factor than with some other gemstones.
• Treatments: Whether the citrine is natural or heat-treated may affect value and should be disclosed.
• Overall appearance: The visual appeal of the finished gemstone is paramount.

Caring for Citrine Jewellery

Citrine is relatively easy to care for, but following a few simple guidelines will help preserve its beauty:

• Clean citrine jewellery with lukewarm water, mild soap and a soft cloth or brush.
• Avoid harsh chemicals, including bleach and household cleaners.
• Protect citrine from hard impacts and sudden temperature changes.
• Avoid prolonged exposure to high heat, which may affect colour in some cases.
• If colour fading is a concern, limit extended exposure to intense sunlight.
• Store citrine jewellery separately to prevent scratching from harder gemstones.

Citrine as a November Birthstone

Citrine is one of the modern birthstones associated with November, alongside topaz. Its warm golden tones make it a popular choice for birthday gifts and personal jewellery for those born in this month.
