Understanding Opal Doublets: A Gemstone Marvel
Opal doublets are a captivating type of gemstone that beautifully merges the enchanting allure of opal with the durability of other materials. This unique combination allows for the stunning play of colour that opals are renowned for, while also enhancing their practicality for everyday wear. In this blog post, I will explore what opal doublets are, how they are crafted, and their significance in the world of gemstones.
What is an Opal Doublet?
An opal doublet consists of two layers: a thin slice of natural opal combined with a backing material, typically made of black potch (common opal without colour), ironstone, glass, or another type of stone. The purpose of this backing is to enhance the opal's play-of-colour, making it appear more vibrant and striking. The doublet structure not only improves the visual appeal but also adds strength to the delicate opal, making it less prone to damage.
The Crafting Process of Opal Doublets
Creating opal doublets involves several meticulous steps:
1. Selection of Opal
The journey begins with selecting a high-quality piece of opal. This choice is based on its colour and clarity. Typically, the opal is a thin slice, as the doublet design requires a delicate layer of the gemstone.
2. Choosing the Backing Material
Next, a suitable backing material is selected. Black onyx is a popular choice because it enhances the opal's colours, but other materials can also be used. Each choice contributes to the overall aesthetic and durability of the doublet.
3. The Bonding Process
The opal slice is carefully bonded to the backing material using a strong adhesive. This step is crucial to ensure durability and longevity. A well-executed bonding process is what makes an opal doublet a reliable choice for jewellery.
4. Finishing Touches
Finally, the edges are polished, and the doublet is cut into the desired shape for jewellery-making, such as cabochons or pendants. These finishing touches elevate the beauty of the opal doublet, making it ready for its new home.
Benefits of Opal Doublets
Opal doublets offer several advantages that make them a popular choice among gemstone enthusiasts:
Enhanced Appearance
The backing material enhances the opal's colours, making the gemstone more visually appealing. This vibrant display of colours is one of the key attractions of opal doublets.
Increased Durability
The doublet structure makes opal doublets more robust compared to solid opals, which can be more fragile. This added strength allows for everyday wear without the constant worry of damage.
Affordability
Opal doublets are often more affordable than solid opals, making them accessible to a wider range of customers. This affordability does not compromise their beauty or charm.
Care and Maintenance of Opal Doublets
To ensure the longevity of opal doublets, proper care is essential. Here are some tips to keep your opal doublets looking their best:
Avoid Harsh Chemicals
Keep opal doublets away from harsh cleaning agents and chemicals that can damage the adhesive or the opal itself. A gentle approach is always best.
Gentle Cleaning
Clean the gemstone with a soft, damp cloth to remove dirt and oils. This simple practice can help maintain the opal's brilliance.
Proper Storage
Store opal doublets in a soft pouch or a jewellery box to prevent scratches and damage. Proper storage is key to preserving their beauty over time.
The Significance of Opal Doublets
Opal doublets hold a special place in the world of gemstones. They represent a harmonious blend of beauty and practicality. For those who appreciate the unique charm of opals but seek a more durable option, opal doublets are an ideal choice. Their stunning colours and affordability have made them increasingly popular in the jewellery market.
A Personal Touch
As someone who loves gemstones, I find opal doublets to be particularly enchanting. Each piece tells a story, reflecting the beauty of nature and the artistry of craftsmanship. Whether you are a collector or looking for a special piece of jewellery, opal doublets offer a delightful blend of beauty and resilience.
Conclusion
In conclusion, opal doublets are a beautiful and practical choice for anyone who appreciates the unique charm of opals. With their stunning colours and affordability, they have become a beloved option in the jewellery market.
