DIABOND is the largest chain store of lab-grown diamonds in Hong Kong.

Firstly, lab diamonds possess the same physical, chemical, and optical properties as natural diamonds, making them indistinguishable to the naked eye, even for experienced gemologists. Therefore, lab diamond rings exhibit the same sparkling beauty. Secondly, many lab grown diamond facilities use clean and renewable energy sources, resulting in a smaller environmental impact and footprint during the whole manufacturing process. Moreover, lab diamonds can be produced at a faster rate and adhere to more ethical standards, aligning with the concept of sustainable development. lab made diamonds are often referred to as “green diamonds”. Additionally, the price of a lab diamond is generally more affordable when compared to natural diamonds, allowing one to obtain lab grown diamond rings or jewellery with larger carat weights, higher clarity, and perfect cuts with a much lower budget. This can lead to significant cost savings, which is why an increasing number of people are choosing lab made diamond rings.

Lab grown diamonds possess the same physical, chemical, and optical properties as natural diamonds, and their appearances are nearly identical. However, their origins of formation differ. Natural diamonds are formed deep within the Earth through geological processes involving high temperatures and pressures over a period of millions of years. On the other hand, lab grown diamonds are created in controlled environments by simulating the high temperature and pressure conditions found in nature. This manufacturing process results in shorter production cycles and more controlled quality for lab made diamonds. The distinction between lab grown diamonds and natural diamonds is similar to that between cultured pearls and natural pearls—they have the same composition but are formed in different locations.

A lab grown diamond is created through chemical or physical processes in controlled environments. One common method is Chemical Vapor Deposition (CVD). In the CVD process, a carbon-containing gas is used as a raw material. Through a chemical reaction at high temperatures, carbon atoms are deposited onto diamond seeds, gradually growing into complete diamond crystals and forming lab made diamonds.

Lab diamonds are 100% genuine diamonds, with the same crystal structure and chemical composition as natural diamonds. Natural and lab grown diamonds share identical physical and chemical properties and cannot be distinguished with the naked eye. Therefore, lab diamonds are recognized as real diamonds and are considered a viable alternative to natural diamonds in the jewellery market. The FTC (Federal Trade Commission) states that “A lab grown diamond is a diamond. It has essentially the same optical, physical, and chemical properties as a mined diamond.”

Lab diamonds can be visually distinguished from diamond simulants (such as cubic zirconia or moissanite). Lab grown diamonds have the same crystal structure and chemical composition as natural diamonds, while simulants are made from other materials and do not possess diamond-like characteristics. Lab made diamonds exhibit similar hardness, refractive index, and optical properties to natural diamonds, whereas simulants cannot replicate these features. The relationship between natural diamond, lab diamond, and diamond simulant is akin to natural pearls, cultured pearls, and plastic pearls.

Yes, lab made diamonds in HK have internationally recognized certificates from organizations such as GIA or IGI. These certificates provide specialized documentation for lab grown diamonds in Hong Kong, verifying their quality and authenticity. The certificates include the 4C grading of the lab grown diamond, which refers to carat weight, color, clarity, and cut. Each lab grown diamond in HK is also assigned a report number using laser inscription on the girdle. All certified lab made diamonds in Hong Kong can be verified through the report number on the GIA/IGI websites. These certificates provide lab made diamond HK consumers with credibility regarding the quality of lab diamonds and enhance confidence when purchasing jewellery made with lab made diamonds.

The primary method of distinguishing a lab diamond from a natural one, is through professional gemological institutions that provide identification and certification. These institutions utilize advanced technology and instruments to examine the physical and chemical properties of all types of diamonds, determining their origin and authenticity. Additionally, lab grown diamonds often have identification marks engraved in the diamond’s girdle or radiated area to differentiate them from natural diamonds. Due to the similarity in chemical and optical properties between lab made diamonds and natural diamonds, traditional gemological testing methods such as “diamond testers” are unable to detect their differences. Identification requires specialized gemological laboratories with highly precise equipment.

Lab grown diamonds have gained high acceptance and recognition from various international institutions. Many renowned jewellery brands also incorporate lab diamonds into their collections and establish separate lines for lab made diamond jewellery. In recent years, lab diamonds have become popular in Western countries, where their sustainable development concept has garnered a lot of support and demand. Locally, the lab diamond Hong Kong customer market is growing, with an increasing number of young couples choosing lab made diamond HK engagement rings.

Each lab grown diamond is unique, depending on its manufacturing process and the expertise of the producer. Customers can choose lab diamonds in HK that suit their preferences and budget, and pair them with different styles of lab made diamond rings to create the perfect piece of jewellery.
