Budget and Payment
In the past, engagement rings had a strong value in terms of property, and we often heard people talk about "the equivalent of X months' salary," but these days, we often have our rings made in a variety of styles to suit our customers' values and requests. The average budget for an engagement ring made at our store is between 300,000 yen and 500,000 yen.
Our custom-made engagement rings are not more expensive than ready-made or brand-name jewelry from specialty stores because they are made to order in the true sense of the word, which means that they are made to order according to your wishes, including your budget.
Please feel free to tell us your budget and we will be happy to work with you to find the perfect engagement ring just for you.

Materials
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 we use 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, we can also apply rhodium coating, 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.
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 we make the base metal so that it develops a white color with our unique formula without coating.
We do not melt your jewelry for processing. We can take back ring frames used for remodeling, etc., so please consult with us.
Diamonds and Gemstones
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 it is around 100,000 yen for 0.2 ct. and around 250,000 yen for 0.3 ct.
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.
How to choose a recommended diamond
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.

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 at our store are provided with a certificate of authenticity free of charge. We use the two major official diamond grading institutes in Japan, the Central Gemological Laboratory or AGT Gem Factory (GIA Japan).

Design
About half of the customers who come to ADAM to have engagement rings made are men who come alone. Even if you do not have a clear design in mind, 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 you in many ways if you consult with us.

Wedding rings are often made in the same design, but there are many cases where the design chosen by the woman does not suit the man, or the man can only wear a simple design because of his work. For example, when a woman's ring design is not suitable for a man, or when a man's job allows him to wear only simple designs.
Our wedding rings can also be arranged, such as increasing the volume or width for only the man's ring. 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 base metal, or attaching stones, etc. Please feel free to let us know.
Unlike most jewelry retailers, we are a custom jewelry store specializing in custom-made jewelry, so we create jewelry that is unique to each customer according to their 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.
We hope that you will feel free to visit our store and tell our staff not only about your requests, but also about any concerns or worries you may have about jewelry.

We offer a one-year warranty from the date of receipt of repair, and will repair the same part of the chain at no charge. Due to the shape of chains such as Venetian chains, ball chains, rope chains, etc., they are more susceptible to stress after repair.
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 our store.
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 it becomes discolored, please bring it to our store.
Care of diamonds, rubies, and sapphires

Care of emeralds, moonstones, and other semi-precious stones
