Sell Your Opal at ALLU

To trace the history of opals, we must scale back to the ancient Roman empire. The nobles and generals of that time were fond of opals, a trend that has never left humanity over the centuries. As of 2020, Australia and Mexico are the two main opal-producing countries. Australia, in particular, accounts for about 75% of all opal production and is known as the supreme home of opals.

Opals can come in a variety of colours, including red, blue, yellow, and purple. Red and orange opals, particularly, are called “fire opals” because of their flame-like hues and garner high popularity in Japan. Opals with blue or green colour effects on a clear, colourless base are called “crystal opals.” However, the most coveted of all these gems is the “black opal,” which glows in red and green hues on a black background.

Opals are also known for the characteristic of containing water: due to the unusual structure that houses the liquid, an unique colouring effect is born within this gemstone. It is said that improper handling of opals can cause them to crack, but there is little need to worry about this in Japan, thanks to the high temperature and humidity that characterise the country’s climate. Jewellery stores, however, sometimes keep a bottle of water nearby as a precaution.

Also, opals are popular not only as jewellery but also as amulets or lucky pieces. Although it is unknown to what extent opals are effective as a charm, many artists and creators wear opals, accepting the belief that they enhance creativity. At ALLU, we strive to buy opals at high prices, so please take advantage of our services at ALLU.

About Icons

The manufacturing and distribution process for brand products emits large amounts of carbon dioxide (CO2) and consumes large amounts of water. The images below represent the amounts of carbon dioxide and water consumption that can be reduced by reusing a product.

Carbon Dioxide (CO2) Reduction

CO2 reduction expressed by the amount of CO2 absorbed by a cedar tree annually.

Water Consumption Reduction

Water consumption reduction expressed by the volume of the 200-litre bathtub.
(Typical household bathtub size)

About Our Calculation Method

Our Calculation Method

The 'Resale Impact' is not a display of an actual environmental reduction but rather a quantification of the environmental impact (CO2 emissions and water consumption) generated by the manufacturing and distribution process that can be theoretically omitted when a customer purchases a product we resell instead of a buying a brand new item of the same type. Since our calculation is predicated on the emissions in the omitted manufacturing and distribution process, actual reductions in environmental impact may differ from our projected estimate.
Since our company does not manufacture goods, our calculations cover any resold goods (watches, bags, jewellery (including bullion), apparel, and accessories).
Our company does not check and verify the actual numerical value of each item's environmental impact (CO2 emission and water consumption) for our Resale Impact. Instead, we base our calculations on data from the LCA database "Gabi*" and estimate the total environmental impact of an item's entire life cycle, from the procurement of its materials to its disposal and/or recycling. Our calculations were overseen by a third-party consulting firm.
Discrepancies in LCA results may occur due to differences in calculation assumptions or deficiencies in the manufacturing process.
Due to revisions in calculations, the latest calculated values of products may differ from those shown on product tags, etc.

Customer Testimonials: Selling Opal Jewellery at ALLU

I’m particularly happy that I got so much for my opal jewellery.

I had some old jewellery but didn’t know what to do with it. I wasn’t overly concerned with selling my items for money, but keeping them wouldn’t do me any good either, as I spent less time going out. Finally, I decided to sell everything, from my opal jewellery to other items I didn’t need. A friend told me about ALLU, a luxury pre-owned trader, so I decided to have my items appraised. I didn’t particularly need the money, but I was happy that my opal jewellery was worth so much. Thank you, ALLU.

Thank you for selling your opal jewellery at ALLU.

Thank you for visiting us to sell your opal jewellery and a number of other items. We are happy to hear that your friend recommended us. The opal gems you brought were very valuable because they had been left in their natural state with no cutting or any other work done to them. As a result, we could offer the highest purchase. It is uncommon to see such natural opals, as the gem is frequently worked on before being set. We were very eager to add your items to our inventory, and this is also reflected in our offer. We are thrilled to hear that you were satisfied with it. Thank you again for visiting us today and choosing to sell your jewellery with ALLU.
The whole experience left me feeling great.

I had an unknown gemstone lying around in my house for some time. I thought it was odd and didn’t know what it could be. One day, when talking about the gem with my friend, they told me about ALLU. I didn’t know the first thing about gemstones, but I decided to try to sell them anyways. I went to the store, had them appraise my gemstone, and it was then that I first heard what it was—an opal. Well, I didn’t know much about opals, if I’m being honest, but I do know that they offered a competitive price to take it off my hands. The whole experience left me feeling great. Thank you, ALLU.

Thank you for selling your opal jewellery at ALLU.

Thank you for visiting us to sell your opal. When you first came in and presented your opal, it was clear that there needed to be more clarity about what you were trying to sell and how much it was worth. We were glad to be able to inform you of what your item was. While you looked surprised at the time, this opal is a lovely gem in excellent condition and, being such a fine item, it was our pleasure to be able to buy it from you. Our appraisal staff determined the value of your opal, and we believe we arrived at an accurate price. If you have any other items you want to sell, we hope you consider taking advantage of our services again. We look forward to your future visits.

Learn About Market Prices and Valuation! Opal Selling Price FAQ

Are selling prices higher for trending designs?

In general, opal rings, brooches and other circular jewellery tend to fetch high selling prices. However, the general rule is that trending designs do not automatically equal high selling prices. The most important factor is the quality of an opal, which is determined by size, lustre and wear. This means that even old designs can be sold at high prices if they are of a high quality. At ALLU, rest assured that our experienced staff members will use their reliable appraisal skills to determine the best selling price for your jewellery.

Does the size of the stone affect the selling price?

Although the quality of an opal is the most important factor, its size can also affect the selling price. If two opals of the same quality vary in size, it can be expected that the larger of the two will demand a higher value based on the scarcity of larger stones.

Is there anything I should bring with me when visiting for an appraisal?

If you have a certificate of authenticity for an opal, please bring it with you. It acts as proof of the value of an opal, so bringing it with you will increase the chance of a high selling price.

Do you buy loose or rough opals?

Yes, we buy loose and rough opals. Depending on the grade of an opal, we may be able to offer a high selling price for it.

What kinds of jewellery do you buy at high prices?

When it comes to opals, black opals in excellent condition are the most likely to fetch a high price. In addition, Red-in-Black opals—rare opals of incredibly high quality with a lush red iridescence in six varying shades—command incredibly high selling prices. It is also important to note that a piece’s design, base metals and grade of supplementary stones (stones other than a piece’s main stone) are important factors when assessing opal jewellery. At ALLU, our experienced staff members will use their reliable appraisal skills to evaluate each of these points to offer you an optimum selling price.
