FAQ
About Shopping
Q: Can you deliver the product urgently?
A: Since our store's jewelry is made to order, it takes about 1.5 to 2 months for delivery. (For bridal rings, about 2 months~) As each piece is handcrafted by artisans, this is the necessary production period. Therefore, we generally decline all requests to expedite delivery due to customer circumstances. We appreciate your understanding.
We are updating the "Estimated Shipping Date" on our blog as needed.

Q: What happens to the delivery if I order both in-stock items and made-to-order items at the same time?
A: Unless you have specific requests, we will ship the made-to-order jewelry once it is completed. If you would like to have in-stock items shipped first, please kindly let us know.
Q: What happens to the wrapping if I order multiple items at the same time?

About the item
Q: Can you make it in a size that is not listed in the selection?
A: We generally do not accommodate sizes outside of the standard sizes, but there may be cases where we can create them. For example, for a ring with [Supported Sizes #6 to #17, size adjustments up to ±1 size], you can generally consider that we can accommodate sizes up to [#5 to #18].
The basic supported sizes are proposed as "the maximum size range where the ring looks beautiful and maintains a perfect circle," including size adjustments. We cannot accommodate sizes that exceed the size adjustment. Additionally, sizes below 0 (negative sizes) cannot be created. Thank you for your understanding.
Q: How do you use the adjuster ring?
A: Our necklace chains come with an adjustable ring (a round loop) attached to the clasp side.
By passing this adjustable ring through the clasp, you can use it shorter by that amount.

Q: Can you convert earrings into clip-ons?
A: Most of the earrings we make at our store are small and do not have a part to attach earring components, so they cannot be changed to earrings.
Q: Can I purchase just one earring?
A: We apologize, but except for items listed as single-ear sales, all products are sold as left-right pairs.
However, there are some types that can be handled if you have lost one side. Please contact us via the repair request form.

Q: I have a metal allergy, is it okay to wear this?
A: Generally, it is often summarized as "metal allergy," but the types of metals that actually cause reactions vary from person to person. The gold used in our jewelry contains various metals such as copper, silver, zinc, and palladium in addition to gold, so for those who are sensitive to these metals, there is a possibility that allergic symptoms may occur even with K18. Additionally, there are cases where reactions occur during the summer when sweating, prolonged use, or temporary reactions to other metals.
Since there are individual differences, it cannot be said definitively, but if you are concerned, please refrain from purchasing.
Furthermore, after purchase, if you feel any abnormalities on your skin or experience symptoms such as rashes, our store will not take any responsibility. Please stop using the product immediately and consult a specialist.

Q: The total length of the chain received is shorter (longer) than stated.
A: We carefully craft necklaces and bracelets to be as close as possible to the specified total length, but there may be some discrepancies during the assembly of each part. A tolerance of ±5mm is accepted. Thank you for your understanding.
Q: The colors of the same type of stone appear different, don't they?
A: When setting the jewelry, we select stones that are as similar as possible, but since all the stones used are natural, there are individual differences in color and transparency. Additionally, the angle, the way the stone is set, and the way the stone absorbs the color of the metal can cause variations in appearance.
Customization and Materials
Q: Can you make it with a different material? (e.g., change K18 to platinum, yellow gold to white gold, etc.)
A: We apologize. For all jewelry, we propose materials that we believe are most suitable for the design, so we do not accommodate such requests. Thank you for your understanding.
In particular, regarding the "birthstone rings made of silver/platinum," which we receive many inquiries about, we do not accommodate this at all due to reasons related to strength and durability.

Q: Can I order with a different ring width?
A: We apologize, but we cannot accept any orders with changes to the width or thickness.
Q: Can I change the chain to a different type?
A: We apologize. For all jewelry, we do not offer customization as we propose the chain that we believe is most suitable for the design. Thank you for your understanding.
Q: Can the length of the chain be changed?
A: It can be changed in ±1cm increments. When ordering, please write your desired length, such as "Chain total length +3cm", in the remarks column of the cart.
Please note that additional charges vary depending on the type and length of the chain.
K10: 990 yen～
K18: 1,320 yen～
(Each including tax/per +1cm)
If you want to shorten it, please understand that we will charge the same amount as the regular length.
* If you wish to change the length after delivery, additional processing fees, etc. will be incurred. Please contact us from this page.

Q: Can the number of stones be changed? (e.g., from 5 stones to 6 stones, etc.)
A: We apologize. Customization and changes to the number of stones are not possible for any jewelry. Thank you for your understanding.
Q: Can I change the stone from diamond to birthstone?
A: We apologize. We do not accommodate requests as we propose stones that we believe are most suitable for the design of all jewelry. Thank you for your understanding.
Q: Can I change to a stone that is not listed in the birthstone list? (e.g., change moonstone to pearl, etc.)
A: We apologize. We do not accommodate requests as we propose stones that we believe are most suitable for the design of all jewelry. Thank you for your understanding.
Q: Can I place a full order or a customized order?
A: We apologize. We do not accept full orders that require creating from design or prototype. Please understand that we also do not accept production using your existing loose stones.

Q: How do I take care of it?
A: Our jewelry is very delicate. Leaving it wet with sweat, etc., can cause discoloration and corrosion. After use, please gently wipe it with a soft cloth.

Q: Is it okay to keep the jewelry on?
A: For all jewelry, it is recommended to remove it each time to keep it looking beautiful for a long time.
In particular, for items with stones or jewelry made of K10 or silver, we recommend not to keep them on continuously and to remove them each time. This is because it can lead to issues such as stone loosening, stone breakage, discoloration, and deformation. Additionally, some birthstones are sensitive to moisture or impact, so caution is necessary.
However, rings made of only precious metal can generally be worn continuously. Just be sure to remove them when entering hot springs, the sea, or a pool, or during intense physical activity.
In reality, many people do wear them continuously, and after delivery, we leave the decision to you. We also offer maintenance services at any time, so please feel free to use them for everyday wear.

Q: Is it okay to use alcohol disinfectant while wearing jewelry?
A: Applying alcohol disinfectant with strong antibacterial properties frequently is honestly not a very good condition for jewelry. Especially some birthstones are prone to discoloration and cracks, so we recommend removing them whenever possible during alcohol disinfection. However, we understand that it can be very difficult to take them off and put them back on while out and about. Therefore, please feel free to use them casually without worrying too much about it.
About baby rings
Q: Can I have a set delivered that includes a baby ring and rings other than a mother ring?
A: We can accommodate that. For example, if you purchase the Baby Ring_matte and the Birthstone Ring_milgrain (4 stones) together, we will deliver them set together in an original box for the baby ring. If you prefer separate packaging, please let us know in the remarks section of the cart.
Q: I want to know how to care for my commemorative plate because it has become dull.
A: The commemorative plate is made of brass, which has a property of oxidizing when exposed to air.
Where it is touched by hand, sebum remains, so (especially in summer) oxidation may proceed at a fairly fast rate. Additionally, even if it is not touched, oxidation will gradually progress over time due to aging.
We have summarized the care methods you can do at home in the blog below. Please take a look if you like.

Q: Can a regular ring be made in baby ring size?

Q: Can I order only the commemorative plate or baby ring (single item)?
A: We do not accept orders for the commemorative plate only. Additionally, we do not accept orders for the baby ring without the commemorative plate.
Q: Can I customize the commemorative plate?
A: We apologize, but we cannot make any changes to the engraving content, engraving position, or design layout outside of the template. We also do not accept changes to the material or shape. Thank you for your understanding in advance.
