This article aims to provide a thorough overview for professionals and enthusiasts operating within the United Kingdom, with specific considerations for the Glasgow region.

What is Zircon Crystal?

Zircon crystal is a naturally occurring silicate mineral composed of zirconium and silicon dioxide. It is one of the oldest minerals on Earth, with some zircons dating back over 4.4 billion years, making them invaluable for geological dating. Its crystal structure is tetragonal, and it typically forms as prismatic or pyramidal crystals. Zircon is known for its exceptional hardness, scoring 6.5 to 7.5 on the Mohs scale, which contributes to its durability in jewelry and its utility in industrial applications.

The mineral is found in various geological environments, primarily in igneous rocks like granite and syenite, as well as in metamorphic rocks and detrital sediments. Major sources of gem-quality zircon include Australia, Sri Lanka, Myanmar, South Africa, and Thailand. The colour of zircon can vary significantly due to trace impurities. For instance, yellow and brown varieties are common, while green and blue hues are rarer and often achieved through heat treatment processes. Blue zircon, often called ‘Starlight Blue’ or ‘Royal Blue,’ is particularly sought after in the jewelry market, especially among consumers in the United Kingdom looking for unique and vibrant gemstones.

The Science Behind Zircon’s Brilliance

Zircon vs. Cubic Zirconia: Understanding the Difference

It is crucial to distinguish between natural zircon crystal and cubic zirconia (CZ). Cubic zirconia is a synthetic material, a crystalline form of zirconium dioxide, manufactured to imitate the appearance of a diamond. While CZ is significantly cheaper and widely used as a diamond simulant, it lacks the natural origin, geological history, and superior hardness and durability of natural zircon. Natural zircon possesses unique geological characteristics and trace elements that contribute to its distinctiveness and value, making it a genuine gemstone with its own merits. Consumers in the United Kingdom are increasingly seeking authentic natural gemstones, and understanding this distinction is vital.

Types of Zircon Crystal

• Zircon (Baddeleyite): This is the pure mineral form of zirconium dioxide (ZrO2), which is less common than zirconium silicate. It is exceptionally refractory and is used in the production of high-temperature ceramics and refractories.
• Zirconium Silicate (ZrSiO4): This is the most common form and the one typically referred to as ‘zircon crystal’ in gemological contexts. It is found in a variety of colours and is widely used as a gemstone and in the production of opacifiers for ceramics.
• Coloured Zircon: Zircon crystal occurs naturally in various colours, including yellow, brown, red, green, and blue. The most commercially significant colours are blue and yellow, with blue zircon often enhanced by heat treatment.
• Hyacinth Zircon: A rare, yellowish-orange to reddish-orange variety of zircon.
• Jargoon: A colourless, pale yellow, or greyish variety of zircon.
• Matura Diamond: A colourless, transparent variety of zircon that resembles diamond.

The colour of zircon crystal can be altered through natural geological processes or artificial heat treatment. For example, brown zircons can be transformed into desirable blue or green hues by heating them to specific temperatures. This process is common in the industry and widely accepted, particularly for enhancing the aesthetic appeal of zircon for the jewelry market in the United Kingdom.
