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.

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'.

コンシーラー買取

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

Pink diamond

Recently, pink coating diamond are seen in the diamond market. Partly due to the less production in natural pink diamond supplies from the Argyle mine, the price is rising. Mainly distributed size is melee size and many people bring in 0.03 carat ~ 0.17 carat size. We can buy coating diamonds at Jewel Cafe.

About Coating diamond

Coating is a process of a colourant such as paint and cover the back of a gemstone (backing) or altering the appearance of a gemstone by using paint as coating on all or part of the surface of the gem to give a colour-modifying effect. A think layer coating may be applied to change the colour of the diamond. For example, an oil-based pen can be used for a rough but effective coating. Tracing the pen along the gridle surface of the diamond, the stone face up appearance reflects the colour of the ink. Metal oxide thin layers are used as a modern coating method. Not only diamonds, similar treatments may be applied to tanzanite, topaz, pearl and quartz. Recently, you can see many coated pink diamonds. The reason is that there is a demand for alternative diamonds due to the decrease of supply from Argyle mine which is producing area for natural pink diamond. Argyle mine is in West Australia and is known for producing large quantities of low-quality diamonds called industrial and near gems. It is producing a high proportion of brown to pink diamonds compared to other diamond mine. It is said that 90& of the total supply of natural pink diamonds and most of the melee sized pink diamonds used as side stones come from this mine. The production of Argyle diamonds had decreased sharply since 2006 and it was said that the mining will end in 2018. When we purchase coating diamonds, of course we look for diamonds in good condition, but we also actively buying coating diamond which have missing part or with damages. Therefore, please visit us for coating diamond assessment. We are confident with the coating diamond buying price.

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.
