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.

Témoignages clients : Vente de bijoux en opale

Je suis particulièrement heureuse d’avoir obtenu une telle somme pour mes bijoux en opale.

J’avais quelques vieux bijoux mais je ne savais pas quoi en faire. Je n’avais pas très envie de vendre mes objets pour de l’argent, mais les garder ne m’apportait rien non plus, car je passais moins de temps à sortir. Finalement, j’ai décidé de tout vendre, de mes bijoux en opale aux autres objets dont je n’avais pas besoin. Une amie m’a parlé d’ALLU, un négociant en produits de luxe d’occasion, et j’ai donc décidé de faire évaluer mes objets. Je n’avais pas vraiment besoin de cet argent, mais j’étais heureuse que mes bijoux en opale valent autant. Merci ALLU.

Merci d’avoir vendu vos bijoux en Opale chez ALLU.

Nous vous remercions de nous avoir rendu visite pour vendre vos bijoux en opale et d’autres objets. Nous sommes heureux d’apprendre que votre amie nous a recommandés. Les gemmes d’opale que vous avez apportées avaient une grande valeur car elles avaient été laissées à l’état naturel, sans aucune taille ni aucun autre travail. C’est pourquoi nous avons pu vous proposer l’achat le plus élevé. Il est rare de voir des opales aussi naturelles, car la gemme est souvent travaillée avant d’être sertie. Nous étions impatients d’ajouter vos articles à notre inventaire, ce qui s’est reflété dans notre offre. Nous sommes ravis d’apprendre que vous en êtes satisfait. Merci encore de nous avoir rendu visite aujourd’hui et d’avoir choisi de vendre vos bijoux avec ALLU.
Cette expérience m’a beaucoup plu.

J’avais une pierre précieuse inconnue qui traînait chez moi depuis un certain temps. Je la trouvais bizarre et je ne savais pas ce qu’elle pouvait être. Un jour, alors que je parlais de cette pierre précieuse avec une amie, celle-ci m’a parlé d’ALLU. Je ne connaissais rien aux pierres précieuses, mais j’ai tout de même décidé d’essayer de la vendre. Je suis allée au magasin, j’ai fait évaluer ma pierre précieuse et c’est à ce moment-là que j’ai appris ce que c’était… une opale ! Pour être honnête, je ne connaissais pas grand-chose aux opales, mais je sais qu’ils m’ont proposé un tarif compétitif pour que je m’en débarrasse. Je me suis sentie très bien après cette expérience. Merci ALLU.

Merci d’avoir vendu vos bijoux en opale chez ALLU.

Merci de nous avoir rendu visite pour vendre votre opale. Lors de votre première visite et de la présentation de votre opale, il était évident qu’il fallait clarifier ce que vous vouliez vendre et combien elle valait. Nous avons été heureux de pouvoir vous informer de la nature de votre objet. Bien que vous ayez eu l’air surpris à ce moment-là, cette opale est une belle pierre précieuse en excellent état et, comme il s’agit d’un objet de grande qualité, nous avons eu le plaisir de vous l’acheter. Notre équipe d’évaluateurs a déterminé la valeur de votre opale et nous pensons être parvenus à un tarif correct. Si vous avez d’autres objets à vendre, nous espérons que vous envisagerez de recourir à nouveau à nos services. Nous nous réjouissons de vos prochaines visites.

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.
