About the Repair Menu
Budget and Payment
In the past, engagement rings had a strong value in terms of property, and we often heard people say, "It's worth X months of my monthly salary. The average budget for an engagement ring at ADAM is between 150,000 yen and 300,000 yen.
ADAM's custom-made engagement rings are not more expensive than ready-made or brand-name jewelry from specialty stores, because they are custom-made in the true sense of the word: made to order, including the budget, to suit your wishes.
Please feel free to let us know your budget and we will be happy to discuss your unique and wonderful engagement ring with you.
ADAM originalSelect Order Wedding RingsThe price of K18YG is 69,300 yen (including tax) when made with K18YG.
Although the price varies depending on the material, ADAM's average price is about 70,000-100,000 yen per ring, or 150,000-200,000 yen for a pair. The bride's ring often has diamonds, etc., so the price may be higher than that of the groom's ring.
A deposit of at least 10,000 yen is required at the time of design decision, and the remaining full amount is due at the time of delivery after completion of the product.

About Lettering
Rings made by ADAM can be personalized with the text of your choice on the inside. Up to 15 characters in two alphabets and numbers can be added free of charge.
If you specify the typeface or wish to have it engraved in Japanese, it can be done by laser marking, but there will be an actual charge (about 5,000 yen per piece depending on the number of characters).
Laser marking and hand engraving are available. In the case of laser marking, not only your favorite text, but also marks and illustrations can be added. Please consult our staff for details.
It can be placed by laser marking or hand engraving. It can be placed on either the inside or outside of the ring.

Laser marking is available. Please consult our staff for details. It is also possible to place it on the outside of the ring.
About Bullion
Yes, of course we can make it.
We also receive many orders for pink gold for the bride and white gold for the groom in the same design.
Normally, white gold is coated with rhodium to make it look whiter, but ADAM uses a unique combination of base metal that makes it look whiter only with white gold, without any coating. The color is softer than platinum. Of course, rhodium coating can also be applied, so please feel free to ask us.
Champagne gold is a shade between white and yellow gold, and is popular for its soft yellowish color and gentle impression. It is recommended for those who feel that yellow gold is too unique.
Lime gold is popular for its cool, bluish yellow color. It is recommended for those who like a stylish and unique impression.
ADAM uses champagne gold and lime gold, which we developed in-house and process from base metal in our workshop.
Custom-made in platinum, K18 gold (yellow, pink, white, champagne, and lime), and silver is available.
As a metal, platinum is characterized by its extremely high melting point and viscosity compared to white gold. Platinum is a more tenacious metal than white gold, especially when it comes to delicate, thin nails used to set diamonds.
However, as for the overall strength of the ring, there is absolutely no problem with either platinum or white gold.
In terms of color, solid white gold is slightly darker and softer white than platinum. Normally, rhodium coating is applied to make it white, but ADAM uses a unique formula to make the base metal so that it develops a white color without coating.
Normally, we will take back the bullion from your ring, make a new ring with new bullion, and then deduct the trade-in amount equivalent to the bullion we took back from the processing fee.
It is also possible to process rings with your own bullion, such as rings that hold memories for you. However, when making a ring, you will need several times as much bullion as the finished product, so when your ring is melted down and used as bullion, new bullion will be added to make the new ring.
There is also an additional fee for reclaiming excess bullion after it has been made. Please consult our staff for details.
About Diamonds and Stones
Diamonds vary in price depending on size and grade.
Generally, diamonds of about 0.2 to 0.5ct in size are often chosen. As it depends on the grade of the diamond, the price is only a rough estimate, but 0.2 ct. is around 100,000 yen and 0.3 ct. is around 200,000 yen.
We will work with you to select the diamond of your choice, whether it is a larger diamond or a higher quality diamond, even if your budget is the same.
ADAM Recommendations for Selecting Diamonds
Yes, of course it is possible. We do not charge any additional fees. If you have a certificate of authenticity, please bring it with you.
We can also perform identification and prepare a certificate of authenticity for diamonds brought to us (actual costs will be charged). Please feel free to contact us.
Yes, of course we can make it. More and more people are remodeling their own engagement rings using the diamonds from their mother's ring. In Europe, where jewelry has a long history, engagement rings are traditionally passed down from generation to generation.
In addition to diamonds, we can also take back the ring's base metal and deduct it from the processing fee.
All graded diamonds purchased from ADAM are provided with a free appraisal certificate. We use the two major official diamond grading institutes in Japan, the Central Gemological Laboratory or AGT Gem Factory (GIA Japan).
Of course it is possible. We will find the loose pieces you are looking for according to your budget. Also, ADAM's owner directly purchases loose gemstones from overseas and displays them for sale in the store. Please feel free to ask our staff.
Yes, we can provide a gemological identification and certificate of authenticity prior to processing. If you are unsure of the type of stone you have, we can have a gemologist identify and certify the stone before processing (actual costs will be charged). Please consult our staff for details.
About Design
About half of the customers who come to ADAM to have an engagement ring made are men who come alone. Even if you have not decided on a specific design, our experienced staff will be happy to discuss it with you. We would like you to visit our store first to see the samples in the store.
The biggest problem when making a surprise engagement ring is how to measure the ring size, but everyone has their own ideas, and we can help in many ways if you consult with us.

However, there are many cases where the design chosen by the woman does not suit the man, or where the man's job requires him to wear only a simple design. For example, if a woman's design is not suitable for a man, or if a man can only wear a simple design for work.
ADAM wedding rings can also be arranged, for example, by increasing the volume or width for only the man. We can also accept requests for the same motif design, but only for the woman's ring, such as making it more design-oriented, changing the type of metal, or attaching stones, etc. Please feel free to let our advisors know.
Unlike most jewelry retailers, ADAM is a jewelry store specializing in custom-made jewelry, so we create jewelry that is unique to each customer according to his or her wishes and budget.
If you are unsure of your own tastes or what kind of jewelry would suit you best, we will listen to your impressions, your age, your lifestyle, and your intended use of the jewelry, and work with you to create jewelry that is unique to you. We will discuss with you the jewelry that is just for you.
Please feel free to visit our store and tell our staff not only your requests, but also any concerns or worries you may have about jewelry.

Silver is a very difficult metal to repair because it conducts heat extremely well compared to platinum and gold, welding itself is difficult, and in the case of items with stones, the possibility of damaging the stones is very high.
Adan will take a look at your item and if it can be repaired, we will keep it for you. Please feel free to contact us.
About Repair Click here for more information.
We are sorry, but we cannot accept repairs that require welding or polishing work for titanium and stainless steel because the melting point and hardness of these metals are very different from those of precious metals.
Although the Atelier takes the utmost care in repairing and processing, there is a possibility that your item may be irreversibly damaged in the course of the work.
In addition, for soft stones, including emeralds and opals, the stones themselves may be damaged even by normal operations, depending on their condition.
In such cases, we are sorry to say that we are unable to offer warranty or reimbursement. Please be aware of the above when you leave your item for repair.
Care and Maintenance
Diamonds never lose their luster, as the saying goes, "Diamonds are eternally brilliant. However, because of its oil-sensitive nature, the diamond may lose its luster as it gets dirty with sebum or other dirt over time. If this happens, cleaning will restore the shine.
To do this at home, dilute a neutral detergent in lukewarm water, brush lightly, wash well under running water, and blot dry with a soft, dry cloth.
If you have time, please feel free to bring them to our store and let us know, as we are always happy to clean them in-store for free.

Pearls are very delicate gemstones. Because they are naturally organic, they do not like to dry out and are sensitive to acids and cosmetics. When worn on a hot day, for example, it is best to use a special pearl polishing cloth to remove sweat and dust to preserve its beauty. A soft towel can also be used. Wipe the necklace by sliding the cloth over it, avoiding pulling on the threads. In addition, wipe the metal clasp (clasp) together. Many clasps are made of silver, and they may oxidize due to perspiration, etc. if left as they are.
Washing pearls with tap water should be avoided, even if they are heavily soiled.
If you are concerned about stains, please bring your necklace to our store and we can clean it, although it will require a thread change.
If it has not been used for a while, silk threads may be damaged, and we recommend that you change the threads. Also, if there is a gap between the pearls and the threads are visible, it is a sign that the threads are stretched.
→directional marker or indicatorClick here for information on pearl thread changes and repairs.
The method of care depends on the base metal and stones used. Please handle your jewelry gently so as not to damage it.
Care of platinum and K18 materials
Use lukewarm water and scrub gently with a toothbrush or similar tool to remove dirt. After washing under running water, wipe well. If deep scratches or deformation is noticeable, please bring the product to ADAM.
Care of silver materials
Use lukewarm water and scrub gently with a toothbrush or similar tool to remove dirt. After washing under running water, wipe well. If the surface becomes darkened, wipe lightly with a polishing cloth specially designed for silver to remove it. Also, be sure to remove the product from a hot spring bath, as it may discolor. If it becomes discolored, please bring it to ADAM.
Care of diamonds, rubies, and sapphires
Use lukewarm water and scrub gently with a toothbrush or similar tool to remove dirt. After washing, wipe well with water. Although the stone is relatively resistant to water and heat, please be careful not to give it a strong shock.
Care of emeralds, moonstones, and other semi-precious stones
Use lukewarm water and scrub gently with a toothbrush or similar tool to remove dirt. After washing, wipe well with water. The stone is soft. Do not subject it to an ultrasonic cleaner as it may cause cracking or chipping. In particular, please be careful not to give it a strong shock.
