[Shinjuku Marui Annex 2F] Pop-up store announcement [6/24 (Tue) ~ 30 (Mon)]


Following on from Hakata, we will be holding a pop-up store in Shinjuku, Tokyo in May!!
In addition to popular sections such as the birthstone feature for each month, the world's top five gemstones, and Paraiba tourmaline,
There will also be original jewelry and cut pieces by Sanjay, a skilled cutter from Sri Lanka.
These are all gemstones that KARATZ has collected from all over the world and can confidently recommend.
You can discover new charms in famous gemstones, or you can come and see rare stones you've never known before. I'm sure both collectors and beginners will enjoy themselves.
The venue will be the same as last time, Shinjuku Marui Annex 2F! Only at a pop-up store can you compare and choose while looking at the products in person! Please feel free to take a look at any gemstones that interest you.
The Shinjuku exhibition will be held for one week. Depending on the day and time, you may be able to enjoy the exhibition at your leisure.
We have some special benefits for you to visit us multiple times during the event, so please come and visit us!

💎Jewelry corner

We plan to bring a large selection of KARATZ original jewelry and Karafuri (Karatts Flea Market) jewelry this time as well!
They are made with great attention to detail, such as ones that change appearance when exposed to black light, and ones that use rare gemstones for the side stones.
*You can try on all items except earrings and pendants.
This ring has an andesine labradorite center stone, commonly known as "blue moonstone," which emits rainbow colors when exposed to light.
You'll be entranced by the soft, gentle light and find yourself staring at your fingers for hours.

Frame name: Charm
Center stone: Andesine labradorite
Side stone: Benitoite
Metal: K18YG
💎The world's top five gemstones corner
This corner features the world's five most famous gemstones: diamond , ruby , sapphire , emerald , and alexandrite .
From affordable items to slightly better items, we hope you will rediscover the charm of gemstones that have been loved since ancient times.


💎Paraiba Tourmaline Special

Paraiba tourmaline continues to fascinate with its unique color that reminds us of the color of the tropical sea . It is a gemstone with an endless charm that makes you want to have more even if you have one.
We will bring you pearls from Brazil and Mozambique, the main producing areas at present. Please compare them and feel the difference in their characteristics.
💎Moonstone Special

The June birthstone "Moonstone" emits a soft glow when light is shone on it . It has been prized around the world since ancient times as a stone associated with the moon.
This time, in addition to the usual "moonstone," there will be a special corner featuring "andesine labradorite" and "peristerite," which are commonly known as "rainbow moonstone" and "blue moonstone."
Both belong to the feldspar group, but when you compare them, you will notice differences in the way their optical effects appear. Please enjoy their unique beauty.

[About the auction listing and trade-in services]

From June 27th (Friday) to 29th (Sunday), we will be offering an auction listing service (Karaoke) and trade-in service exclusively at the Shinjuku Marui Annex!
*This event will not be held at the Hakata Marui venue. We appreciate your understanding. Karaoku is a new service provided by KARATZ in partnership with Aucnet, the world's largest dealer auction operator.
We will sell the jewelry you entrust to us at an auction attended by professional gem buyers from Japan and abroad, allowing you to sell for a higher price than you would with a typical purchase service.
*Some gemstones cannot be auctioned depending on their type and quality.
▶ Click here for more information about Karaoke
KARATZ can also trade in items that are difficult to put up for auction or items you wish to sell.
The trade-in amount will be given to you as a coupon to be used at the event, which can be used to purchase products or towards the processing fees for custom-made jewelry.
<What is the trade-in service?>
Unlike a purchase service where you are paid in cash, trade-in is a service where you are paid in the form of a coupon that can be used at events, Karatz Stores, etc.
In exchange for using the points to purchase products at Caratz, we will buy them at a higher price than we would buy them at.
If you are considering purchasing an item or creating custom jewelry, we recommend using our trade-in service.
*Due to regulations at Yurakucho Marui, we are unable to provide a purchase service, so this time we will only be able to offer the item for auction or trade-in. Thank you for your understanding.
*Jewelry and precious metals that are traded in will mainly be sold to overseas business partners (jewelers). They will not be sold at Caratz stores.
● Target items
Jewelry and bullion of K9 or above, Pt750 or above *This also includes broken earrings, cut necklaces, and earrings that are only missing one piece.
*Loose stones and rough stones are not included.
● Trade-in method
If you are interested, please contact the KARATZ staff.
● [Reference] Market price for purchasing precious metals
<As of Monday, June 2>
Gold: 16,716 yen/g Platinum: 5,256 yen/g

Weekdays (except the first day) from morning to evening tend to be relatively relaxed when you can view the items at your leisure, so this is especially recommended for those who would like to leisurely enjoy the jewelry or consult about custom orders.

*24th (first day), 28th (Saturday), and 29th (Sunday) are excluded.

You can also customize it by changing the side stones to Paraiba tourmaline, alexandrite, hot pink spinel, etc. Try placing it in the frame and expanding your imagination.
[Points to note when purchasing loose stones]
