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.

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.

18-Karat Gold (K18) Market Price FAQ

How is the price of 18-karat gold determined?

18-karat gold is made up of 75% pure gold, with the remaining 25% being a mix of other metals, so its price is lower than that of pure gold. 18-karat gold is mainly processed into jewellery. However, if not scratched or damaged, branded 18-karat gold products can sell for prices higher than their market value.

What is the difference between 18-karat and 14-karat gold?

18-karat gold and 14-karat gold differ in regard to their gold purity. The purity of gold is usually expressed in fractions out of 24- the closer to 24, the higher the purity: 18-karat gold is 18/24, meaning it is 75% pure; 14-karat gold is 14/24, or a purity of 58.3%; 14-karat gold is 14/24, or a purity of 58.3%.

How is 18-karat gold used?

Solid 18-karat gold can be found in necklaces, rings and other jewellery. Pure gold is too soft by itself and needs to be mixed with another metal to increase its strength. Coloured gold, such as yellow gold and green gold, also mainly consists of 18-karat gold. 18-karat gold is also used in watches and lighters, as it is practical and easy to work with.

How long does it take to appraise 18-karat gold?

The time required for an 18-karat gold appraisal depends on the appraisal method, the type of item, and the number of items. For example, the average time to appraise one 18-karat gold necklace is 10-15 minutes. If you have any questions, please do not hesitate to ask our staff in person at our store or over the phone.

Is it possible to sell a tangled 18-karat gold necklace that cannot be disentangled?

The short answer is yes. An inextricable 18-karat gold necklace, a deformed ring, an incomplete set of earrings- all of these can still be sold. Gold and other precious metals possess inherent value, even if they no longer function as accessories. We would be happy to buy any item which we appraise as 18-karat gold.

Does the price of 18-karat white gold differ from that of regular 18-karat gold?

18-karat white gold is an alloy consisting of 75% gold and 25% silver or palladium, which gives it a silvery-white colour. Likewise, other hues of gold, including yellow gold and pink gold, are produced by mixing various metals into gold. The value of these gold alloys depends on the value of the mixed metals, so the price of 18-karat gold and white gold will differ.

18 Karat Gold (K18) Widely Popular in Watches and Accessories

18 Karat gold is a gold alloy that has a good balance of durability, luxury, and cost and might be the most common purity among gold alloys. The reality is that 18 Karat gold is used for a large number of fashion items, such as accessories and watches. ALLU has a long track record of buying 18 Karat gold, and in this section, we will give an overview of 18 Karat gold, explain how it differs from pure gold, and look at items in which 18 Karat gold is used.

What is 18 Karat Gold?

18 Karat gold is a general term for a gold alloy with a purity, in other words, a gold content of 75%. Gold purities are defined as a fraction out of 24; in 18 Karat gold, that fraction is 18/24 or 75%. 18 Karat, 18K and K18 refer to the same 75% ratio of gold to other metals. 18 Karat is a common gold alloy widely used as a material for accessories in particular. Silver and copper are commonly used in these alloys and account for 25% of the non-gold metal content. Colour varies greatly depending on the ratio of metals in the alloy. Many items generally referred to as coloured gold, such as yellow gold, green gold and red gold, are made from 18 Karat gold.

The Differences Between 18 Karat Gold and Pure Gold

Gold does not deteriorate easily. However, it is soft and weak to heat. These characteristics are most pronounced in 100% pure gold. Another characteristic of gold is that it is easy to mix with other metals. For this reason, gold is commonly mixed with other metals in accordance with the desired application. As an alloy, the added metals serve to improve gold's relative softness, giving way to a harder compound. Thus, used as an alloy, the shortcomings mentioned above are reduced, and these gold alloys can be used in items where damage is a potential concern. 18 Karat gold is mixed at a 75% gold to 25% ratio, so the hardness is greater than pure gold. Further, the refining of 18 Karat gold has purposes beyond just improving hardness. Mainly to add colour to the shine of the original gold. This colour changes according to the proportion of non-gold metals in the alloy. In terms of 18 Karat gold, the impact of the alloyed metals on the colour is striking. Due to this, among coloured gold items, 18 Karat gold is a commonly used purity.

Items in Which 18 Karat Gold is Used

Higher-purity gold has a high rate per gram and is valuable as an asset. Of course, although the value of 18 Karat gold is high, it is rarely used in physical assets such as ingots (gold bars) and coins. Due to the characteristics mentioned above, it is mainly used as a material for making accessories. It is often used as a material for basic accessories such as necklaces, earrings, bracelets, rings, etc. In addition, it is also common to see 18 Karat gold in coloured gold items where alloyed metals adjust the colour. Including the standard yellow gold, various colours are used according to the item or need, such as rose gold, which is popular with women, or the simple, appealing white gold. Compared to higher-purity gold, 18 Karat gold's hardness also allows for thinner shapes when designing products. As such, 18 Karat gold is an excellent material for making accessories due to its freedom in colour and moulding. Indeed, 18 Karat gold is often used to achieve solid and original designs for jewellery brands. Particularly when it comes to colour, even while using the same 18 Karat gold, products will vary greatly depending on the alloy's unique ratio to each brand. Another use of 18 Karat gold is as the material in gold watches for the world's leading luxury watch brand Rolex. The characteristics to achieve the luxury of gold as well as the robustness that Rolex models demand, is unique to 18 Karat gold. A number of Rolex classic models, such as the Day-Date, Sky-Dweller, and GMT Master II, have been released in 18 Karat coloured gold variations.

The High Selling Price Potential of 18 Karat Gold

Items made of 18 Karat gold have been lauded by many due to their variation in colour and ease of handling. Among those who do not value the brilliance of gold above all, 18 Karat gold's popularity is comparable to higher-purity gold such as 22 Karat gold and pure gold. Of course, 18 karat-gold items are also frequently traded in the pre-owned market. At ALLU, we welcome and actively make offers for 18 Karat gold items such as necklaces, rings and watches at high prices. Our appraisal price considers not only the basic price of gold by weight but also the product's design. For popular 18 Karat gold items, you may receive an appraised price that exceeds your expectations.

ALLU Frequently Asked Questions

How do you decide the selling price of gold, platinum and other precious metal accessories?

The selling price of precious metals such as gold and platinum is determined according to the 'market price', which is set on a daily basis.
We measure the items you bring to us and derive the appraisal value based on the market price x weight. However, in some cases, if the item possesses an exceptional design as jewellery, we may consider the additional value.

My gold/precious metal does not have any engravings. Can I still get it appraised and sell it?

We can evaluate the item, and if we are able to determine that it is gold, we can purchase it. However, please understand that it may take us some time to check the ratio and other details of the precious metal in question, and there may be cases where we can not proceed with a transaction due to the evaluation.

Can I sell broken items such as broken necklaces, rings with missing stones, or earrings with one pair missing?

We will evaluate the item(s) in question, and if we can determine they are made of precious metals, we can make an offer for them.

How long does it take for an appraisal at the store?

We estimate 10 to 15 minutes for a single item. It depends on the item and the quantity, so please ask our staff when you visit.

Do scratches and stains affect the selling price?

Generally, the condition of the item does not have a major impact.
In the case of ingots, depending on their condition, they may be treated as scrap, which may significantly affect the selling price. For other precious metal products, we will have to actually observe the item in question before making a decision.

Can I sell old coins and foreign gold coins?

If, according to our regulations, we can determine that the item(s) can be treated as precious metals, we can make an offer for them at the best possible price.

Some commemorative and foreign gold coins have a premium value, as they are hard to obtain due to their small circulation. If you bring such gold coins to us, they may be worth more than ordinary precious metals.

When is the best time to sell gold and precious metals?

Compared to past gold market prices, the current prices can be considered quite advantageous, so we believe that the present is a favourable time to consider selling.

However, the market price of gold and precious metals fluctuates daily, so it is very important to notice the timing when the market price is high.

Is the selling price different for ingots and gold jewellery?

Yes, the selling price of ingots and gold accessories is different.
Ingots have their own values and prices: we can make an offer at the ingot price if the brand is recognised in our regulations. On the other hand, even if it is 24-karat gold, gold jewellery is treated as scrap, so that the price will be slightly lower.

Is there a difference in selling price between ingots with and without engraving?

Ingot prices are determinable only for the brands recognised by our regulations. Even if the item in question has the shape of an ingot, if it is not engraved, or if the issuing brand is not one of the recognised brands, there may be cases where it cannot be treated as an ingot.
