Customer Reviews

Offered me with good price even without receipts

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!

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!

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 Philippines. 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.

Diamond's 4Cs

About the 4Cs of Diamonds

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.
  • Colour

  • Clarity

  • Cut

  • Carat

The degree of colorlessness is typically used to assess the colour grade of gem-quality diamonds. Diamonds that are chemically pure and structurally perfect are colourless and have a higher value. The GIA colour level reliably tests colorlessness by contrasting it to colour samples of each colour grade under particular lighting conditions.

Color variations between diamonds can be slight and undetectable to the untrained eye, but these differences have a significant impact on the appearance and price of diamonds. The GIA colour rating system for determining the colour of diamonds is the most widely used in the global gem industry.

Diamond's initial 'D' reflects the highest level of transparency. The lower the rating, the yellower the product.

JEWEL CAFE
+FAQ for Color
Q
Why is the GIA color rating grade 'D-Z' instead of 'A-Z'?
A
Before the birth of the GIA color rating, there were no clear criteria, there was a mixture of rating grades such as 'A, B, C ...', '0, 1, 2 ...'', 'I, II, III ...'' and misleading subjective expressions such as 'Gemuru' and 'Blue White'. As a result,customers were sometimes confused. The GIA introduced levels with a 'D-Z' notation beginning with a 'D' to avoid confusion with current ones when determining a colour rating based on logical and straightforward standards. Other rating charts are rarely used now that the GIA colour rating has become a strong consistency standard and has spread across the world.
Q
Specifically, how do you determine the color of a diamond?
A
Human understanding of diamond colour is strongly impacted by the light source and background. As a result, GIA evaluates the colour by contrasting it to various colour samples that meet the requirements for evaluation under the given circumstances. Judgment will be made by two or more appraisers for each diamond. If the results of each judgment do not match, or depending on the weight and quality of the diamond, the judgment will be left to another appraiser. The rating grade will not be finalized until the judgment results are agreed upon.

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.

A tapered diamond is also called a tapered baguette cut diamond. 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.

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.
