ALLU Frequently Asked Questions
How do you decide the selling price of gold, platinum and other precious metal accessories?
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?
Can I sell broken items such as broken necklaces, rings with missing stones, or earrings with one pair missing?
How long does it take for an appraisal at the store?
Do scratches and stains affect the selling price?
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?
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?
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?
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?
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.
