[Shinjuku Marui Annex 2F] Pop-up store announcement [May 23rd (Fri) - 29th (Thu), Shinjuku]

Carats Pop-up Store Event
Carats Pop-up Store

A pop-up store will be held in Shinjuku, Tokyo in late May!

This issue's feature on gemstones based on their properties is " Gemstones that Emit Beautiful Fire " - when they sparkle in the light, you will be greeted with a brilliance that will take your breath away.

In addition to the traditional birthstones, the world's top five gemstones, and the popular Paraiba tourmaline, there will also be many new loose stones by Sanjae, a skilled craftsman from Sri Lanka, and the latest KARATZ original jewelry!

From famous gemstones that everyone knows to rare stones that you rarely see, please come and see the carefully selected gemstones that KARATZ has collected from all over the world.

This time, the event will be held in Shinjuku for the first time in a while. The space will be much larger than last time, so I think you will be able to take your time looking around.
If you work nearby, why not stop by on your way home and be soothed by the jewels?

The best thing about a pop-up store is that you can compare the same types of gemstones and choose while looking at them in person.
If you see any gemstones that interest you, please come and check them out.

This time, the exhibition will be held for a week. If you want to take your time looking around, we recommend going during the day on a weekday (except for the first day) or in the evening on a weekend.
We also have special offers that will allow you to visit us multiple times during the event.

💎Jewelry corner

We plan to bring a large selection of items this time, including KARATZ original jewelry made by KARATZ staff with attention paid to even the side stones, and Karafuri (Karatts Flea Market) jewelry!

This ring features a deep, vibrant color-shifting amethyst as the center stone. When exposed to black light, the pink sapphires and hackmanite side stones fluoresce vividly, taking on a completely different look.

Frame name: Vivace
Center stone: Color shift amethyst Side stones: Pink sapphire, hackmanite, tanzanite Metal: K18PG


The new work has been completed!

First, let us introduce the ring that uses the new original design frame, Chandulier, which was created with the image of a chandelier in mind.

This ring combines gorgeousness and glamour with a dark Oregon sunstone center stone that shows off metallic schiller.

The different shades and characteristics of the blue gemstones complement each other, creating an exquisite harmony. The sharp sparkle of the platinum adds to the sophisticated atmosphere.

Center stone: Bicolor sapphire Side stones: Tanzanite, Paraiba tourmaline, purple sapphire, London blue topaz Metal: Pt950


Next, we would like to introduce two rings that use May's birthstones.

Let's start with emeralds, which have a beautiful vibrant green color.

Emerald Ring Spiritosa

The arabesque design arm and diamond side stones give this ring an elegant feel, making it suitable for both casual and formal occasions.


Frame name: Spiritosa
Center stone: Emerald
Side stones: Diamonds Metal: K18YG


This is a heart-shaped jade ring.

Since it uses emeralds as side stones, it is especially recommended for those looking for a May birthstone ring. In addition, the green diamond (lab-grown) on the opposite side of the emerald creates a gorgeous sparkle. This is a ring that you can enjoy with a mature feel.

[About the auction listing and trade-in services]

From Friday, May 23rd to Sunday, May 25th, we will be offering an auction listing service (Karaoke) and trade-in service exclusively at the Shinjuku Marui Annex!

Karaoku is a new service from KARATZ in partnership with Aucnet, the operator of one of the world's largest B2B auction sites.
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.

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, at the "Karatts Store", 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 Shinjuku Marui Annex regulations, 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 Friday, April 22nd>
Gold: 16,990 yen/g Platinum: 4,779 yen/g
*The price is calculated based on the bullion market price on the day of the transaction (which changes daily).

■ Weekday-only lottery

If you purchase products between May 26th (Mon) and 29th (Thu), you will have the chance to enter a lottery to win original goods!

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.
After enjoying shopping, try your luck with the weekday-only lottery! It's your chance to win some wonderful original goods.

*Since Hakata Marui will be open for four days, there will be no weekday-only lottery.

💎Custom-made consultation corner


You can request a custom-made ring, pendant, etc. on the spot using the gemstone you selected on the day.
This also applies to loose stones previously purchased from Caratz and stones purchased from Shimizu Precious Stones. If you are considering purchasing, please bring them with you.

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]
If you would like to have a custom-made item made from a loose stone that you have previously purchased from Caratz or Shimizu Precious Stones, please be sure to read and agree to the following precautions before bringing it in.
