How to Pick the Right Opal Gemstone

Opal gemstones, with their mesmerizing play of colours, are a true wonder of nature. From fiery reds to iridescent blues, opals come in a stunning array of hues that make them captivating choices for jewellery. However, selecting the right opal gemstone requires careful consideration to ensure that you find a piece that aligns with your preferences and suits your needs. In this comprehensive guide, we'll explore the key factors to consider when picking the perfect opal gemstone. 

Understanding Opal Types and Varieties

Opals are classified into several types based on their appearance and colour play:

• Precious Opals: These opals exhibit a captivating play of colours known as "opalescence." Precious opals can display a range of colours, and their value is often determined by the intensity and variety of colour play.

• Fire Opals: Known for their fiery red, orange, and yellow colours, fire opals lack the play of colours seen in precious opals. Instead, they dazzle with their vibrant hues.

• Common Opals: These opals lack the play of colours seen in precious opals and are often translucent or milky in appearance. Common opals can come in various colours, including white, gray, and green.

When selecting an opal, consider the type that resonates with your preferences. If you're drawn to the captivating play of colours, precious opals are the ideal choice. If you prefer bold and vibrant hues, fire opals can be a stunning option. Common opals, on the other hand, offer a unique charm with their diverse colours and translucence.

Evaluating Opal's Play of Colours

The play of colours, also known as opalescence, is a mesmerizing phenomenon seen in precious opals. It occurs when light interacts with the internal structure of the opal, creating a stunning display of hues that shift as the stone is viewed from different angles. When picking an opal gemstone, consider the following aspects related to its play of colours:

Intensity: The intensity of the colours is a crucial factor. Look for opals that exhibit strong, vivid colours that are easily visible even in different lighting conditions.

Variety: A diverse range of colours that transition smoothly and create a harmonious blend adds to the beauty of the opal. Seek opals with a captivating interplay of hues.

Pattern: Opals can display various patterns, such as pinfire, flash, and harlequin. Patterns add depth and character to the stone. The highly prized harlequin pattern features large, distinct colour patches in a geometric arrangement.

When evaluating the play of colours in an opal, examine it under different lighting sources to witness the full spectrum of hues. Keep in mind that the play of colours is one of the most enchanting aspects of opals, so prioritize stones that exhibit this phenomenon effectively.

Opal's Body Tone and Transparency

Opals come in a range of body tones, which refers to the base colour of the stone. Body tones can vary from white and light gray to black. The body tone affects how the play of colours is perceived:

• Light Body Tone: Opals with a light body tone tend to have a more translucent appearance. The play of colours is usually bright and vibrant, making them a popular choice.

• Dark Body Tone: Opals with a dark body tone can create a striking contrast with the play of colours. The colours often appear more saturated against the dark background.

• Black Opals: Black opals, with their dark body tone, are particularly prized for their intense play of colours. Their rarity and deep, captivating hues make them highly sought after.

When selecting an opal, consider how the body tone enhances or contrasts with the play of colours. Keep in mind that personal preference plays a significant role, as some individuals may prefer the contrast of a dark body tone, while others may be drawn to the brightness of a light body tone.

Opal's Cut and Shape

The cut and shape of an opal can greatly influence its overall appearance and how the play of colours is showcased. Some considerations include:

• Cabochon Cut: Cabochon, a smooth, rounded, and polished cut, is the most common cut for opals. It enhances the play of colours and showcases their beauty without facets that can interfere with the phenomenon.

• Shape: Opals are available in various shapes, including oval, round, pear, and free-form. Consider the shape that complements your jewellery design and personal style.

• Orientation: The orientation of the cut can affect how the play of colours is seen. Some opals are cut to display the colours from a specific angle, so ensure the stone is positioned to highlight its best features.

When choosing an opal's cut and shape, think about how it will be incorporated into your chosen jewellery piece. The cabochon cut is often preferred for rings, earrings, and pendants, as it offers a smooth surface that's comfortable for daily wear.

Opal's Durability and Care

Opals are relatively softer gemstones compared to diamonds and sapphires. To ensure your opal remains beautiful for years to come, follow these care tips to maintain its appearance and longevity:

Avoid Extreme Temperatures: Opals are sensitive to extreme temperature changes, which can cause them to crack or lose their play of colours. Remove opal jewellery before engaging in activities that involve rapid temperature shifts, such as hot tubs or saunas.

Avoid Harsh Chemicals: Opals are porous gemstones and can be affected by chemicals found in household cleaners, perfumes, and cosmetics. Remove your opal jewellery before applying lotions or engaging in cleaning tasks.

Gentle Cleaning: Clean opal jewellery using a soft, damp cloth. Avoid using abrasive materials or harsh brushes that can scratch the surface. If needed, use a mild soap with lukewarm water, but make sure to rinse thoroughly to remove any soap residue.

Storage: Store your opal jewellery separately from other gemstones to prevent scratches. Consider using a soft pouch or individual compartments to keep your opals safe from potential damage.

Regular Inspections: Periodically inspect your opal jewellery for any signs of damage or wear. Loose stones or damaged settings should be addressed by a professional jeweller to prevent further issues.

In conclusion, picking the right opal gemstone involves considering factors such as the type of opal, play of colours, body tone, cut and shape, and durability. By understanding these key aspects and taking proper care of your opal jewellery, you can enjoy the captivating beauty of opals for years to come. Whether you're drawn to the fiery hues of fire opals or the enchanting play of colours in precious opals, the perfect opal gemstone awaits to adorn you with its unique and iridescent charm.
