Higher price for my 4ct fancy diamond heart shape with GIA certificate.

I saw Jewel Café in website that they buy any diamonds even fancy cut especially with GIA certificate. I done survey others place for my 4ct fancy cut diamond heart shape and I came to Jewel Café to get free estimations. Nice place and the environment so relax and calm. All the lady staff are so friendly and so talkative. I am not feeling awkward to waiting during the appraisal. I also have a hot coffee and Japanese snacks. Once they quote the price I feel so satisfied with the price and so huge different with others place that I surveys. They also added me extra 10% from website promotion. So nice and love the member privileges and the lucky draw gift. Despite the huge million dollars, they made the transfer immediately on the same day and I felt reassured as a big company. Highly recommended.

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.

Purchase of Multiple Diamonds

In the Roman writings of ancient Europe, diamonds were introduced as a type of substance called 'Adamas', which described hard objects, including steel. The word 'Amadas' was transformed into Diamant via Diamas, which became the origin of the word diamond. The word 'Amadas' comes from the Greek word meaning 'unconquerable power. The diamond is the birthstone for the month of April, and is hard, beautiful, shining, and captivating. It is also the birthstone for the month of April, and its words are 'eternal bond, purity, and fortitude'.

Purchase of Tapered Diamonds

A tapered diamond, also called a tapered baguette cut diamond, was originally used not as a main stone but as a side stone or a type of melee diamond in a ballerina type design surrounding the middle stone. A bucket is a shape often used for melee stones. The term 'bucket' is derived from the French word for 'rod'. The tapered bucket cut is a trapezoidal shape, where 'taper' means 'tilt' and 'baguette' means 'bar'. The tapered bucket cut is a trapezoidal cut. When the trapezoidal shapes are aligned in the same direction, a curve is created to express a delicate design.

The most popular type of colored diamond is the natural pink diamond, which is a rare stone and commands a very high price because there are so few of them. Blue diamonds and yellow diamonds are the next most popular as they are often used in high brand jewelry.

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 depending on other factors such as colour and clarity, but the evaluation is free, so please feel free to visit us.
Q
Is it possible to appraise something without a certificate or license?
A
Yes, we can still purchase your diamond jewelry even without certificates! While having a certificate certainly increases the confidence in the appraisal process, at Jewel Cafe, we conduct extensive research on diamond authenticity and stay updated with the latest market trends. Therefore, even if you don't have certificates, we can provide you with a confident and fair price for your diamonds.
Q
Is it okay to bring an old diamond I purchased a long time ago?
A
Yes, there is no problem with older diamonds. Diamonds are composed of highly durable atoms, and their beauty is preserved even with age. Depending on the cut, they can even produce a new brilliance. Therefore, at our store, we do not give negative evaluations to older diamonds and can offer you a price that meets your expectations.
Q
Can the jewelry store pay a better price?
A
No, even in specialized shops like ours, we conduct high-value diamond purchases. While some jewellery stores may have systems such as trade-in (using the trade-in value towards the purchase of new jewellery and paying the difference), and may repurpose the diamonds they purchase for other jewelry, Jewel Cafe refrains from secondary use of purchased diamonds. Instead, we aim to list them in markets where fair prices can be achieved, ensuring customer satisfaction through our pricing approach.
Q
Is it possible to sell tiny diamonds attached to the side of a larger diamond?
A
Yes, we can purchase even very small diamonds that are set as side stones alongside larger diamonds. These small diamonds are commonly referred to as melee diamonds, and Jewel Café offers high-value purchases for them as well. The demand for melee diamonds has been increasing globally.
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 market price for diamonds does fluctuate. The global market price for diamonds can vary daily due to factors such as the calculated production volume in the countries of origin, changes in demand for diamonds, and the impact of exchange rates. As a result, the value of diamonds can change significantly over a span of a few years. Therefore, it is advisable to make a prompt decision when considering selling diamonds that you no longer need.

#3 Ranking

Diamond with AGT certificate

Until 2015, AGT Gem Laboratory was affiliated with GIA and was in charge of GIA Japan’s lab department and GIA G.G (Graduate Gemologist) educational institution in Japan. It is said to be the strictest appraise and judgement in Japan, and especially it has a good reputation for judging the slightest shades of colour diamonds

About Diamond with certificate

In order to judge the value of diamond relatively, the method of evaluating at 4C is now widely supported. 4C is the initials for Carat, Colour, Clarity and Cut. The scales other than the weight scale in the 4C evaluation scale were originally developed by the American Gemological Education Institute GIA (Gemological Institute of America). The GIA method is currently the most widely used in Japan. It should be noted here that the beauty of diamond-cut stones is not only determined by the 4C rating. The assessment of beauty is subjective, and no unified agreement has yet been reached. Therefore, it is necessary to understand the limitation that the 4C evaluation is rarity evaluation. In Japan, appraiser organization that are members of the AGL (Asia Gemological Laboratory) are particularly reliable in Japan and each organization is strictly graded based on AGL standard which based on GIA (Gemological Institute of America). Among them, only the cut evaluation is graded according to the new GIA standard and all the organization affiliated with AGL (Asia Gemological Laboratory) are based on the new standard of American GIA. The AGL certification No. is written on the diamond loose sorting bag that has been evaluated based on the AGL standard. Specifically, CGL (Central Gem Laboratory), AGT Gem Laboratory (GIA-JAPAN), DGL (Diamond Grading Laboratory), GTC (Japan Gem Testing Centre) etc. are the diamond appraiser organization which has high reliability in the market and is used well. Also, since only AGT Gem Laboratory is a member of AGL, the AGL certification No. is stated but the grading is not based on the AGL standard but on the GIA (Gemological Institute of America) standard and has a reputation for strictness. When we purchase your diamonds with certificate, of course we look for diamonds in good condition, but we also actively buying diamond with certificate which have missing part or with scratches. Therefore, please visit us for diamond with certificate assessment. We are confident with the diamond with certificate 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.

Tips of diamond jewelry 1 carat diamond necklace with certificate

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.
