Frequently Asked Questions
-
QWhat is the best time to sell gemstone jewellery??
-
AThe value of gemstone jewellery goes up and down every day, but the market for second-hand gemstone jewellery is booming, so this is the best time to sell. In addition, the valuation proposed by Jewel Cafe is not only based on speculation on the purchase price of the gemstone jewelry, but also considers various background factors of the jewelry item, so we can always recycle at a higher price.
-
QIs there any additional cost involved in purchasing or assessing gemstone jewellery?
-
AOur gemstone jewelry identification service is completely free. Even if you are dissatisfied with the final estimate, we still do not charge any fees. Jewel Cafe is famous for quick store acquisitions, but we also provide free home delivery and on-site acquisition services. Welcome to choose the acquisition method that best suits you.
-
QAny tips for increasing your gemstone jewelry acquisition rate??
-
AIf you bring gemstone jewelry along with other designer items, this will result in a higher assessed price. Combinations such as "jewelry, boutique bags" or "metals, fine watches, diamonds" are no problem. We will propose a 10–20% bonus for simultaneous identification of a large number of items. For details, please contact the store staff.
-
QI have gemstone jewelry that I want to sell. Do I need to make an appointment?
-
AThe appraisal of gemstone jewellery does not require an appointment. Welcome to visit anytime! Jewel Cafe's stores are located in prime locations such as MRT stations and department stores, so you can also stop by when shopping. However, when there are many people, you may have to wait for a while, so in order to conduct appraisal and acquisition more smoothly, it is better to make an appointment in advance.
-
QWon't jewelry stores offer higher appraisal prices??
-
Ait's not true. Only a professional recycling shop like us can offer a higher appraisal price. Jewelry stores only accept trade-in (exchange the value of old jewelry for new jewelry, and recharge if it is not enough), or it is also possible to install the recovered gemstones on another jewelry. On the contrary, Jewel Cafe not only does not reuse the purchased jewelry, but also strives to offer a fairer and more satisfying purchase price.
-
QCan jewelry without warranty be authenticated?
-
AWe also accept jewelry without a warranty! A warranty can indeed enhance the credibility of the jewelry, but Jewel Cafe is constantly looking for the latest research on gemstone verification and market conditions, so we are confident that we can still provide the jewelry without a warranty. Jewelry offers an appraisal price that will satisfy you.

Amethyst purchase
Trivia of Amethyst
About Amethyst purchase
Amethyst has a wide range of colors from pale lilac to dark purple, but in the 19th century it was believed that internal manganese was the cause of coloring. Since then, it has become possible to think that some organic component may be involved in the color because of the property that changes color easily with heat.But in fact, however, it has been found that the change in the arrangement of iron ions, which are present as impurities inside, due to radiation is the color factor of amethyst. Therefore, if you add iron ions to a colorless crystal and then irradiate it with radiation, you can easily artificially create amethyst.
Amethyst that can cause discoloration even when exposed to ultraviolet rays is called a "color change amethyst" (or color change type amethyst), or a green transparent crystal is a "green amethyst" which is often called. Amethyst is also widely used as a power stone, and various theories are in agreement that it acts as a tranquilizer. Brazil, Uruguay, and Madagascar are famous as amethyst production areas. They have a rough characteristic that they are pale purple in Brazil, purple close to red and violet in Madagascar, and deep purple in Uruguay. Amethyst that is so beautiful and high-quality that it has been praised is the "Kaga purple" which is produced in Japan. When purchasing amethyst, good condition is of course, but we are also actively making Amethyst purchase even if the condition of the product has removal of side stones or distortion of the metal, so please feel free to make a request for the Amethyst purchase assessment. We are confident in our Amethyst purchase price.
