[Kobe Marui 1F] Pop-up store announcement [April 22 (Wed) - 28 (Tue)]
The KARATZ pop-up store is returning to Kansai for the first time in three years! It will be held for the first time in Kobe in April!!
We look forward to welcoming you with a wide range of gems, from familiar ones like the world's five major gemstones (diamond, ruby, sapphire, emerald, alexandrite) and Paraiba tourmaline, as well as birthstones for each month, to rare and unusual stones.
We also offer a wide selection of products that allow you to enjoy gems in various ways, including beautifully cut gemstones by skilled domestic and international polishers, meticulously crafted jewelry using KARATZ original settings, tools such as penlights and loupes, and rough stone polishing kits.
In addition, we will be bringing many new loose stones that have just arrived from the Tucson Gem & Mineral Show, one of the world's largest jewelry exhibitions.
This is a valuable opportunity to see and purchase KARATZ gemstones, which are usually only available on our online store, up close!
You can compare multiple stones, examine them with a loupe, and check the finer details.
We can also lend you tools, so please feel free to visit even if you don't have your own.
Our knowledgeable staff will be on hand, so please feel free to ask any questions you may have.
Our "Custom Order Consultation," where you can place a stone in a setting on the spot and see the finished image, is always very popular.
Please try creating your own unique piece of jewelry by choosing a stone and designing it yourself.
We also offer various benefits for purchasers, such as coupons that can be used at events starting the next day, and a gemstone lottery for purchases over 10,000 yen!
The event runs for a week, so please find a convenient day and time to come and visit us!

You can choose from approximately 40 types of settings (*), just like regular custom orders, and we offer a variety of gemstone types, including diamonds, alexandrites, and Paraiba tourmalines. *Some settings may have size or cut limitations. *The processing fee (setting price) varies depending on the design and metal. *There are also sets made with gemstones from Shimizu Kiseki, and event-limited products.

We will be offering a trade-in service and auction consignment (Karaoku) only from April 24th (Friday) to 26th (Sunday)!
If you have jewelry made with precious metals (gold, platinum), please bring them during this period!
For trade-ins, the payment will be in the form of coupons that can be used at the event, instead of cash. You can use them for product purchases or as processing fees for custom-made jewelry, so please take advantage of this if you are planning to purchase an item or create a custom piece.

＜About the trade-in service＞
The trade-in service, unlike a buying service where you receive cash, is a service where you receive payment in the form of coupons that can be used at events or on the "KARATZ STORE".
In exchange for using the coupons for purchases at KARATZ, we will buy your items at a higher price than a typical buying service.
＜About Karaoku (Auction Consignment Service)＞ 
Karaoku is a KARATZ service conducted in partnership with Aucnet Inc., which operates one of the world's largest business-to-business auctions.
We consign your jewelry to an auction where professional jewelers from Japan and overseas gather, which can lead to higher selling prices than typical buying services.
*Some items may not be eligible for auction consignment depending on the type and quality of the gemstone.

For items that are difficult to consign to auction or items you wish to sell, KARATZ can purchase them at a later date.
*Due to Kobe Marui's regulations, buying services cannot be offered. Therefore, only auction consignment or trade-ins will be handled at the event venue. Thank you for your understanding.
*Jewelry and precious metals acquired through trade-in will primarily be sold to overseas trading partners (gemstone dealers). They will not be sold on the KARATZ STORE.
●Eligible Items
Jewelry and precious metals of K9 or higher, Pt750 or higher
