"Good environment and excellent staff

STORE BASED
I passed by this shop when I went to the market. I was really in need of cash at that moment, so I just asked them about my diamond rings that I was using at that time. It’s a white gold ring with a diamond 4 carat. They asked me if I got the certificate, but I told them I lost them because I moved to a new house, so lots of my things were lost. I gave them both my rings. While waiting, they served me with drinks and snacks. Besides that, they explain to me roughly what things that they buy. They gave me a really good price, considered the pros and cons of diamond rings also white gold. I will come here again to sell my branded items. Thank you for your excellent and kind services.

I sold my diamond at Jewel Cafe Aeon Equine last week. It was an old diamond ring that I have not used for 15 years. Still, it was 4 carat with 916 ring gold. Luckily, I got a really good offer price. Even though I don’t have my GIA certificate because it has already been lost, but still because the diamond got a good cut. The staff answer me with a nice tone and treat me well. I called before I came here, and they told me it was okay. I’m so happy with the service here. I definitely will come here again to sell my other jewelries.

If you happened to want to find a shop that can buy your branded diamond ring, I would highly recommend this Jewel Cafe shop. But in my case, you must bring your ring certificate or else they will buy your ring according to the material of your ring. Actually, I just pass by the shop. Then ask about the ring to the staff at the counter. Their service was really good! They explained to me detailed and said that if I have the cert, than they can buy according to the brand. I went straight home after that and looked for all the details. It was good to experience here. They said my diamond ring got a good cut according to the 4C. This explained to me why they needed the GIA cert. I got a really good price offer.

"The store has improved more on buying diamonds

Thank you for selling your big diamond to us! As we start to expand our connection with the overseas country. As Japan does not expand enough on buying diamonds, that’s why we prefer buying diamonds with the GIA certificate. With this, we can rate you according to the GIA grading. All the 4 C’s matter. As for your diamond ring, it got an excellent cut. We will pay all the payment with instant cash! Thank you for your kind words towards the services that we provided. We will try to improve and enhance our service also the buying process for diamonds. We are looking forward to seeing you again!

In certain conditions, the Gemological Institute of America (GIA) created the world's first standard for representing diamonds. Today, the Color / Clarity / Cut / Carat Weight '4C for Diamond Quality' is recognized worldwide as the international standard for assessing the quality of any diamond.

Currently, the GIA method is the most widely used in Japan. At Jewel Cafe, our skilled staff will assess your loose diamond purchase with a wealth of knowledge.

Frequently Asked
Questions

Faq
Q
Does the size of the stone (diamond) affect the assessed price?
A
Yes, a carat is the unit of measurement for the size of a diamond stone, so the greater the number of carats, the higher the measured worth. Diamonds, on the other hand, have other measurement points such as colour, transparency, and cut, so the price will be decided after a detailed analysis.
Q
Does the assessment change depending on the shape of the diamond?
A
Yes, the price of a diamond varies based on its shape (cut). A brilliant round cut is the most common style, but there are also emerald, marquise, oval, and heart shapes. The price varies based on other factors such as colour and clarity, but the evaluation is free, so please fell free to visit us.
Q
Is it possible to appraise something without a certificate or license?
A
Yes, even though you don't have a certificate, we'll buy it!

Q
Is it okay to bring an old diamond I purchased a long time ago?

As a consequence, even though it's an old diamond, we will deliver a price that suits your desires while preventing a negative appraisal.
Q
Can the jewelry store pay a better price?
A
No, for example we as a purchase specialties stores, also offers high price purchase. In the case of a jewellery store, trade-in (buy new jewellery for the selling price and pay the difference later) is a scheme that some retailers have implemented, and the diamonds bought will be used for other jewellery. Jewel Cafe avoids reselling imported diamonds and instead sells them in markets where they can be sold for more fair rates, aiming to provide consumers with reasonable prices.
Q
Is it possible to sell tiny diamonds attached to the side of a larger diamond?
A
Yes, we'll be able to buy it. Wakiishi is usually referred to as melee diamond, but Jewel Cafe often buys melee diamond at a premium. The demand for melee diamonds is all over the world.
Q
Are you able to assess just the diamond stones?
A
Yes, we'll also buy diamond stones (loose diamonds). Diamonds that aren't embedded in jewels are known as loose diamonds. We also weigh diamonds and assess their consistency, but even though you don't have a certificate, we will gladly purchase it.
Q
Will the purchase price of diamonds fluctuate?
A
Yes, the global market price of diamonds also fluctuates daily. The value of diamonds may change significantly every few years, for example, because they are affected by the calculated amount of the country of origin, the needs of the diamond itself, and the exchange rate. If you think that you no longer need it, we recommend that you make a decision as soon as possible.

About Ideal cut diamond

For diamond cut grade, it is generally said that the excellent cut is the best cut. Excellent cut refers to proportion category such as table size, crown angle, pavilion dept, etc. are within a certain range and based on the proportions published by Marcel Tolkowsky in his “Diamond design” book in 1919. This proportion is called “Ideal cut” and many experts has the same opinion that ideal cut is the great method to lead the diamond brilliance. Ideal cut is shown as following proportion. Table: 53%, crown angle: 34.5-degree, pavilion dept: 43.1% (40.75 degree) (average girdle diameter as 100%), overall dept exclude girdle: 59.3% (average girdle diameter as 100%). Excellent cuts, which used by many grading institutes today, allows slight wider range of proportion than ideal cuts. Ideal cut is a rainbow coloured cut, which looks dark but has rainbow coloured glitter. The excellent standard of Japan (G.I.A.) has a wider range of excellent evaluation than ideal cut, so there are various types from diamonds with brightness to fire. When we purchase ideal cut diamonds, of course we look for diamonds in good condition, but we also actively buying previous ideal cut diamond which have missing part or with scratches. Therefore, please visit us for ideal cut diamond assessment. We are confident with the ideal cut diamond buying price.

Tips on how to sell diamond jewelry!

●Select a shop that specializes in diamonds. Instead of selling, some gem shops have implemented a trade-in scheme (buy fresh gems for the selling price and pay the difference later), and some shops measure uniformly based on the number of carats and grades. We recommend selling at a specialized shop that has a strong track record of buying diamonds.

●Bring both a license and a certificate if you have it with you. It would be more accurate to verify the quality of diamonds, particularly if you have a credential, and this can influence the estimated amount too. Especially for large diamonds, there are many stores that attach a certificate when purchasing, so please bring it with you.

●If you don't think you'll need it, we suggest making a decision as soon as possible. If you think you may need it someday, the product's value may drop or you might lose it, so if you decide not to use it, we suggest selling it as soon as possible.

● If you have a large diamond (1 carat or more) but no certificate, contact the certificate distributing agency, have a certificate issued, and then sell it for a high price. This is because some buyers pay higher prices for a certificate, but there is a chance that the price will rise in the future, particularly for big diamonds. It would be typical to provide a GIA certificate or a central gem certificate.

● Pay close attention to the form of storage. While diamonds are extremely hard, they can be chipped due to the angle of damage or friction between diamonds. Separate it from other jewellery when handling it and keep it in a protected spot.

● Bring your jewellery without removing the stones (diamonds) from your jewelry. The same is true even if you want to sell only stones (diamonds), because there is a possibility that the diamonds will be damaged when you remove them with the equipment you have at home. At Jewel Cafe, stone removal is free, so please feel free bring it to us.

Diamond Jewelry Trivia of the Week

Tips of diamond jewelry
1 carat diamond necklace
with certificate
クオーカード

Big solitaire diamond necklaces are a classic piece of diamond jewellery. It's a jewellery that literally fastens the diamond, removes needless development, and highlights the diamond's initial beauty at the collar, but the big diamond has a greater appearance and offers an elegant performance. As a result, many jewellery stores sell this item, but we also purchase a lot of them at our shop adding to purchase higher-quality diamonds or are tired of designing as the main reason.


There was a period when higher-quality diamonds were used for rings, then for necklaces, and finally for earrings, depending on the use. Since I was looking at the diamond closer to my own eyes, I preferred to concentrate on quality as much as possible when it came to rings. Earring are casually guided because necklaces tense to draw more attention. Each has a specialized role, and diamonds can be used effectively.


The grade of the diamond may be clearly labelled, particularly in the case of a large diamond necklace with a single stone (solitaire), but there are distributors that use diamonds with a slightly lower rank in the above period. Therefore, when purchasing a new item, we recommend that you choose a necklace with a certificate that clearly states the quality of the diamond.


Also, if you want to buy a new design necklace or replace it with a higher-grade diamond, please come to Jewel Cafe, where you can sell your diamonds at a high price.
