"Offered me with good price even without receipts

STORE BASED
Thank you for your last time. It helped me a lot. Now I’m on my way home to my hometown Australia. I came to your shop because it came out 1st on my google search. They also accept all my jewelries even without receipt because mostly of them were gifts as wedding gifts. I’m facing a bit of difficulties through my previous selling because I’m not local, but the staff did a full check with my passport and visa and did simple questioning on me. I fully understand all this as they need to follow all the procedure stated by the company. The staff was so nice and really offered me a very good price because all of them were 916. She also understands that I want to use money to go back to Australia. I’m glad my custom-made blue diamond ring they can buy. They offer me quite a reasonable price. They also explained to me very clearly. Thank you again!

"The staff were professional!

STORE BASED
I dropped by this shop after I bought my computer spare part. Then, they greet me nicely and cheerfully. The staff followed the SOP strictly, which to me is so amazing as the COVID cases kept rising. I felt safe here. They ushered me to the confront table and while they were filling in the form, they served me with snacks and drinks. I want to sell my diamond ring as I’ve got this as a present from my friend. So, I don’t have any certificate. They did all the checking process, my diamond is authentic. They offered me a reasonable price as they said the carat was quite big. Besides, my ring is made of white gold 750. I definitely will be back here again.

"They buy my custom made diamond ring!

STORE BASED
Thank you for your kind service last time. I love the service here. I want to sell my wedding ring because I can’t wear it anymore. But due to my love for the blue color, it’s a bit hard to find a seller in Malaysia. I did some research, and I found this shop. Luckily, they can buy. First, it’s a bit hard to sell my blue diamond ring, but because I still kept the GIA certificate, so they can accept my diamond ring. It passes all the process. They offered me quite a nice price. As long I can get good value, then I’m okay with it.

"We do buy blue diamond ring

As we, Jewel Cafe, we started to establish in Japan a diamond purchasing business. If you have the GIA certificate, then we can give you a real good deal according to the GIA rate. Indeed, it’s a bit hard to find a color diamond buyer here in Malaysia as Malaysia is not really into the diamond market. Do call us if you have any questions more on your diamond collection. We hope to see you again!

4Cs of Diamonds

Diamond’s 4Cs
There was no universal indicator for measuring diamonds until the mid-twentieth century. 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.

Purchase of Loose Diamonds

A loose diamond is a bare diamond, meaning the diamond itself has not been processed into jewelry. A loose diamond is a diamond that has not been processed into jewelry. The 4C grading scale, other than the weight scale, was first developed by the Gemological Institute of America (GIA). Initially, the GIA (Gemological Institute of America), a gemological education organization in the United States, developed the 4C scale on its own. 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.

When the trapezoidal shapes are aligned in the same direction, a curve is created to express a delicate design.

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! While having a certificate would give you more confidence in the appraisal price, Jewel Cafe conducts regular analysis on diamond authenticity and conducts the most current market research, but even though you don't have a certificate, we will provide you with a confident price.
Q
Is it okay to bring an old diamond I purchased a long time ago?
A
There are no problems with old diamonds. Diamonds are hardened atoms in a stone. Its elegance is maintained even though it is aged, and depending on the cut, it can produce a new radiance. 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.

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.

1 carat diamond necklace

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.
