Kimberly diamond brand comes from a small town named Kimberly in South Africa. In 187, people found an extremely hard and shiny rock in this town. Later, humans discovered that it came from a mineral deposit buried deep underground for hundreds of millions of years. This mysterious rock was named diamond. Since then, the name of the town "Kimberly" has become synonymous with diamonds, and people from all over the world who are looking forward to getting rich overnight have flocked to this South African town to find their dreams.

at the beginning, in order to continue the origin of Kimberly and diamond culture, Shanghai Kimberly Diamond Co., Ltd. took the lead in registering the "Kimberly" trademark, combining ancient diamonds with modern oriental civilization throughout the operation of the whole enterprise, and devoted itself to every link to create the brand image of "China Diamond Expert" with first-class quality.

"Six Guarantees" service to create an eye-catching brand image

In recent years, Shanghai Kimberly Diamond Co., Ltd. has rapidly developed into a group specialized diamond company integrating diamond design, cutting and grinding, inlay, distribution and retail. The company has a young, knowledgeable, innovative and effective management leading group, and a group of management teams with professional training and qualifications such as CIA, HRD, FCA and CAC. A large number of experienced and skilled production technicians carefully create each unique diamond jewelry of Kimberly.

At present, Kimberly's marketing network with diamond franchise stores as the main sales form is all over the country. In 1995, Kimberly Company took the lead in putting forward the solemn promise of "six guarantees service" in the industry based on the principle of "I am for everyone and everyone is for me": fidelity, quality, price, replacement, washing and warranty. At that time, when the diamond jewelry culture was not optimistic and the jewelry market was still dominated by gold and platinum, this kind of commitment was undoubtedly unprecedented, but it was this bold and emboldened commitment that won the recognition and trust of consumers. Since then, Shanghai Kimberly has established its own core diamond decoration culture-Kimberly's "six guarantees" special service. Each Kimberley diamond ornament is equipped with an appraisal certificate issued by a national authority to ensure that the quality level and platinum content of the diamond meet the national standards and that the diamond ornaments purchased by customers will not depreciate. According to the introduction of Kimberly Diamond Liuyang Store, as long as the diamond ornaments purchased by Kimberly Company are intact and the bills and certificates are complete, any diamond ornament with the same value or above can be exchanged for free in any Kimberly franchise store in China for life.

Modern people have the characteristics of pursuing personalized design and humanized service when consuming. According to this feature of consumers, Kimberly updates the styles of diamonds in time, and new styles are put on the market every month, so as to satisfy consumers' psychology of seeking novelty and change with each beautiful diamond ornament. As long as customers like it, they can change to Kimberly diamond jewelry with updated styles every month. For example, the newly marketed "Kiss" diamond ornaments are very popular with couples, and many people have come to exchange them, so that Kimberly diamond ornaments can witness the everlasting love. Kimberly's "Six Guarantees" service and the nationwide sales network have truly realized the promise of "free exchange in different places for life in China", which has made customers' good wish that "owning a Kimberly diamond ornament is equivalent to owning a Kimberly diamond franchise store". A customer of Kimberly told reporters that the jewelry he bought at the beginning of the opening of Kimberly Liuyang Store has participated in Kimberly's prize-winning activities twice, and it was changed to a new style at the beginning of this year. Now the price of diamond ornaments has risen, and it is really cost-effective to buy diamond ornaments.

With the popularity index of Kimberly diamonds soaring in the market, enterprises are also rising rapidly in the competitive market. In 22, Kimberly started the project to build an international brand of Kimberly Diamond, and successively set up branches in Hong Kong, Belgium and Canada. In 23, the company paid a huge sum of money to build a large diamond cutting and grinding base in China. This year, the company passed the British Standards Institute (BS1)IS91 quality management system certification, which also means that Kimberly Diamond has obtained the passport of the international market and has become an international diamond brand going abroad.

anyone who knows a little about diamonds knows that there are four criteria to measure the value of a diamond: carat weight, color, clarity and cut. Because the English names of the four standards all start with "C", they are abbreviated as "4C" standard. In addition to the recognized 4C standard, Kimberly put forward the 5C standard for its products from a more stringent point of view: quality assurance. Kimberly's diamond quality has been affirmed by the authoritative departments in the industry, and Kimberly's brand image of "China Diamond Expert" has also been widely recognized by the society. On March 15th, 22, Kimberly Company was awarded as "National Diamond Jewelry Industry Quality and Service Integrity Demonstration Enterprise". In the fourth quarter of the same year, the General Administration of Quality Supervision, Inspection and Quarantine conducted a major inspection of the national jewelry market. In view of the fact that all the industry standards of Kimberly diamond ornaments have withstood the inspection and reached the standard, the China Association of Foreign Trade and Economic Cooperation Enterprises awarded Kimberly the title of "Best Credit Enterprise in China" and the China Consumer Foundation awarded Kimberly diamonds as "a brand with stable quality, perfect service and satisfactory consumers".

according to the domestic market evaluation of authoritative organizations, in recent years, Kimberly diamond ornaments have become one of the well-known brands with the least market complaints and the most popular customers in the diamond ornaments industry. Kimberly adheres to the business philosophy of "Success comes from quality, brand comes from honesty, and the market delivers brand value", which is tailor-made for successful people and has achieved the brand image of "China Diamond Expert". What is the difference between synthetic diamonds and natural diamonds?

(1) Glass diamond: It is easy to distinguish a fake diamond made of glass, because it has a low refractive index and does not have the flashing color light of a real diamond, which can be known by a slightly experienced person at a glance.

(2) Synthetic cubic zirconia: This is the most ideal diamond substitute or imitation first introduced by the former Soviet Union. It is a man-made compound without natural minerals. Since the advent of cubic zirconia, many other artificial gem raw materials have only been used as substitutes for other low-grade gems, and are no longer used to grind counterfeit diamonds. Because of its high refractive value, experienced people can distinguish diamonds from synthetic cubic zirconia by identifying this special fire color.

(3) Crystal and Topaz: The transparent crystals of these two natural minerals are also a bit like diamonds after polishing, but they both lack the flickering color light. And they are all "non-isotropic body" gems, while diamonds are "isotropic body" gems, so it is easy to distinguish them with the polarizer of gem identification instrument.

(4): Synthetic moissanite has strong birefringence, that is, it has two refractive indexes, and the difference between the two refractive indexes is great. Therefore, a very special optical phenomenon is produced. When the polished synthetic moissanite faceted gem is observed with a magnifying glass, it can be seen from its top surface that there is obvious double shadow between the bottom surface and the ridgeline. And diamonds, because they are "isotropic body" gems, have no shadow phenomenon.

(5) Artificial sapphire: colorless and transparent artificial sapphire can also be used as a substitute for diamonds after polishing. But it almost disappears in the "diiodomethane" specific gravity liquid, and the edge of the real diamond is dark and very clear.

(6) Artificial rutile: Rutile is a common natural mineral, and its component is titanium dioxide. Because its refractive index (2.61-2.9) is higher than that of diamond (2.42), it can shine brightly and change like a rainbow after being polished into a gem. Because of its strong refractive index, Rutile, like zircon, can see the bottom from the top with a magnifying glass.

(7) synthetic spinel: the difference between it and diamond is that it lacks flashing color light. When it is immersed in the specific gravity liquid of diiodomethane, the outline will be blurred, while the outline of real diamond is very clear. 1. The accurate and reliable way to distinguish true and false diamonds is to measure the thermal conductivity of various

diamond substitutes or counterfeit products with a diamond tester (i.e. thermal conductivity meter), and the problem of distinguishing true and false diamonds will be solved.

2. It is the simplest and most reliable method to measure the hardness of all kinds of fake diamonds with "standard hardness tester". The "standard hardness tester" is a rectangular box with a size of only 65× 55× 23mm. After opening the cover of the box, there are four standard hardness tablets with a mirror-smooth surface, which have a Moh

hardness of 6, 7, 8 and 9 respectively.

3. If you want to know directly whether a gem is a real diamond, you only need to carve Bian Shixuan's standard piece with a hardness of 9

, and if you can scratch it, it is a real diamond. Anything that can't be scratched proves that its hardness is less than 9

or equal to 9, and it is a fake diamond.
