Why is Opal so Valuble?
It is no opal secret that opals are the most valuable and sought-after variety of gemstone. Even if you have never heard of the term, it is nearly impossible for anyone interested in the world of jewellery not to have seen at least an image of one. With its mesmerising play of colour and rare beauty, opal has captivated jewellery enthusiasts and collectors worldwide.
However, it is one thing to say that an opal is valuable, but another thing to answer why.
Opals are diverse gemstones, with no two being identical. It is this simple fact that has led to the creation of the many opal classifications that exist today.
There are three main aspects one must consider when determining an opal's quality (and therefore value). These are as follows:
- Colour
- Pattern
- Clarity
Once you understand how these three values interact, you are well on your way to truly understanding what makes an opal valuable. And, even more so, understanding why black opal stands on a pedestal in terms of value and status.
Opal Colour & Body Tone
It is no secret that an opal's colour is by far its most prominent feature. As eye-catching as it is iconic, the colours contained within the stone react to light, moving together to create an unpredictable and ever-changing display.
Although colour is the primary allure of opal, many will note that not every opal will appear vibrant. Although many things can impact this, the main one to consider is what is known as an opal's 'body tone'. This term describes the 'darkness' of the opal, which serves as the foundation on which the colour is formed.
This means that a darker body tone will allow for much brighter colours, whereas a lighter one will have a more subdued 'pastel' appearance.
Australian black opals are a distinctive stone, as they have a grey-to-black base tone that causes the body of the opal to be darker than that of other opals in the same price range.
A black opal strikes a unique balance between a dark body tone and vibrant shifting colours. This is ultimately what allows for a scenario where a smaller black opal with more colour is priced higher than a larger stone of a different opal type (such as boulder or crystal). Some say that black opals are incredibly pricey, while others contend that their value is relative to market factors (supply and demand). Whatever you may believe, it is no secret that black opal has captivated opal lovers globally.
Opal Clarity
Clarity refers to the presence or absence of visible flaws or inclusions within an opal, and this can have a major impact on the price of an opal stone. Opals free from visible imperfections command a higher value compared to those exhibiting noticeable inclusions or cracks. However, in some instances, inclusions can contribute to unique patterns or enhance the play of light, thereby augmenting an opal's value. Opals with clear and transparent bodies, devoid of significant blemishes, are highly prized for their ability to showcase the play of colour without any hindrance.
The Range of Value
The value of an opal can vary significantly depending on its quality, size, and the intensity of its play of colour. Australian black opals, specifically those from Lightning Ridge in New South Wales, are regarded as some of the finest (and most expensive) in the world. These opals are highly prized for their deep and vibrant colours, making them even more valuable and sought after.
When considering a black opal or any other opal stone, it's essential to verify its authenticity and quality. Working with reputable jewellers and gemstone experts is crucial to obtaining a genuine black opal of exceptional quality and value. These experts can guide you in selecting the right stone, assess its authenticity, and provide expert craftsmanship when creating a black opal ring or necklace.
Be wary, just because something is labelled 'black opal' does not mean it will be worth the accompanying price. Colour is the most crucial element to examine when looking at opal of any type. Look for bright ‘fire’ in the opal; bright red flashes that can be seen even out of direct light are a prime example of a quality gem.
Whether set in a pendant or incorporated into a statement necklace, an opal is a true showstopper and a testament to the beauty and rarity of Australia. Embracing anopal is to celebrate nature's artistry, making it a timeless addition to any jewellery collection.
