The Kiel Diamond Factory: Precision Manufacturing of 0.07 Carat Diamonds, SI1+ Clarity, G+ Color
This article details the operations of a specialized diamond manufacturing facility located in Kiel, Germany, focusing on the production of small, meticulously crafted diamonds weighing 0.07 carats, exhibiting SI1+ clarity, and boasting G+ color grades. We will explore the intricacies of their manufacturing processes, the specific target market, the range of services offered, and the factory’s role within the broader diamond industry as a wholesale supplier and potential source for customized diamond solutions.
The Kiel factory is a dedicated diamond manufacturing plant. It operates with a focus on the precise and efficient production of small diamonds, specifically those weighing 0.07 carats. This specialization allows the factory to streamline its processes, optimize equipment for handling these diminutive stones, and cultivate a highly skilled workforce adept at working with this specific size range. The factory does not engage in mining or rough diamond sourcing directly; instead, it sources rough diamonds from reputable suppliers who adhere to ethical sourcing standards, including the Kimberley Process Certification Scheme. This ensures that all diamonds processed in the Kiel facility are conflict-free.
The “SI1+ clarity” designation refers to the diamond’s clarity grade according to industry standards. SI1 stands for “Slightly Included 1,” indicating the presence of minor inclusions visible under 10x magnification by a trained grader. The “+” suggests that the diamonds within this category are at the higher end of the SI1 range, meaning the inclusions are minimal and do not significantly detract from the diamond’s overall brilliance and appearance. This carefully managed clarity grade provides a good balance between visual appeal and affordability.
The “G+ color” designation indicates the diamond’s color grade, also assessed using industry standards. The G color grade places the diamonds within the “near colorless” range. Diamonds in this range exhibit only faint traces of color, noticeable only when compared side-by-side with diamonds of higher color grades (D, E, and F). The “+” again suggests a position towards the higher end of the G color grade, meaning these diamonds are very close to being completely colorless and possess a bright, white appearance. This near colorless quality ensures the diamonds have excellent brilliance and are visually appealing.
The factory’s strategic focus on 0.07 carat diamonds with SI1+ clarity and G+ color reflects a market demand for high-quality, yet affordable, small diamonds. These diamonds are frequently used in various applications, including:
Pavé Settings: Small diamonds are ideal for pavé settings, where they are closely set together to create a glittering surface. This is a common design element in rings, pendants, earrings, and bracelets. The consistent size and quality of the Kiel factory’s diamonds make them perfectly suited for this application, ensuring a uniform and aesthetically pleasing appearance.
Accent Stones: 0.07 carat diamonds can be used as accent stones to enhance the beauty of larger gemstones or add sparkle to intricate jewelry designs. Their consistent size and quality ensure that they complement the main stone without overpowering it.
Channel Settings: These diamonds can also be set in channels, providing a sleek and modern look in rings, bracelets, and other jewelry pieces. The uniform size of the diamonds ensures a clean and even appearance within the channel.
Micro-Pavé Settings: With advances in jewelry making techniques, these diamonds are also suitable for micro-pavé settings, offering intricate and delicate designs.
Watches: Small diamonds are often used to adorn watch faces and bezels, adding a touch of luxury and sophistication. The precise cut and consistent quality of the Kiel factory’s diamonds are crucial for maintaining the overall aesthetic of the timepiece.
Fashion Jewelry: The affordability of 0.07 carat diamonds with SI1+ clarity and G+ color makes them a popular choice for fashion jewelry, allowing designers to create stunning pieces at accessible price points.

The Kiel factory’s manufacturing process involves several key stages:
Rough Diamond Sourcing: The factory carefully selects rough diamonds from trusted suppliers who adhere to the Kimberley Process and other ethical sourcing standards. The rough diamonds are chosen based on their potential to yield 0.07 carat diamonds with SI1+ clarity and G+ color.
Planning and Marking: Skilled diamond graders carefully examine each rough diamond to determine the optimal cutting plan. This involves identifying any inclusions or imperfections and determining the best way to maximize the yield of high-quality diamonds. The rough diamonds are then marked with precise cutting lines to guide the cutting process.
Cutting: The cutting process involves using specialized diamond saws and cutting wheels to shape the rough diamond into the desired round brilliant cut. This requires precision and skill to ensure that the diamond’s proportions and symmetry are optimized for maximum brilliance.
Bruting or Girdling: This process involves shaping the girdle (the outer edge) of the diamond to create a perfectly round shape. This is typically done using a diamond lathe and requires a steady hand and meticulous attention to detail.
Polishing: The polishing process involves using a polishing wheel coated with diamond powder to smooth and polish the facets of the diamond. This removes any imperfections and creates a brilliant, reflective surface. The polishing process is crucial for maximizing the diamond’s brilliance, fire, and scintillation.
Quality Control: Throughout the manufacturing process, rigorous quality control measures are implemented to ensure that each diamond meets the specified standards for size, clarity, color, and cut. Diamonds that do not meet these standards are rejected or re-processed.
Grading and Certification: Once the diamonds have been polished and inspected, they are graded by experienced diamond graders using industry-standard grading systems. The diamonds are then sorted and classified based on their clarity, color, and cut grades. While the factory itself may not provide formal certifications from third-party gemological laboratories like GIA or IGI for every individual 0.07 carat diamond due to cost considerations, they may offer batch certifications or provide documentation outlining the grading standards used and guarantees of conformity to the specified characteristics (SI1+ clarity, G+ color, and cut grade).
Cleaning and Packaging: Before shipment, the diamonds are thoroughly cleaned to remove any dust or residue. They are then carefully packaged in protective containers to prevent damage during transportation.
The Kiel factory likely utilizes advanced technology and equipment to optimize its diamond manufacturing processes. This may include:
Laser Cutting Machines: Laser cutting machines offer precise and efficient cutting of rough diamonds, minimizing waste and maximizing yield.
Automated Polishing Machines: Automated polishing machines can polish multiple diamonds simultaneously, ensuring consistent quality and reducing labor costs.
Computer-Aided Design (CAD) Software: CAD software is used to create detailed cutting plans and optimize the diamond’s proportions for maximum brilliance.
Diamond Grading Equipment: The factory utilizes specialized equipment to accurately assess the clarity, color, and cut of each diamond. This may include microscopes, color comparators, and proportion analyzers.
Automated Sorting Systems: Automated sorting systems use computer vision and robotics to sort diamonds by size, clarity, and color, increasing efficiency and reducing the risk of human error.

Through its commitment to quality, ethical sourcing, and sustainable practices, the Kiel factory plays a vital role in the diamond industry supply chain. The factory, as a whole, is a vital supplier to a wide range of jewelry manufacturers, and provides the world with diamonds that meet very specific standards.
The 0.07 carat size is also ideal for use in cluster settings, where multiple small diamonds are grouped together to create the illusion of a larger stone. This technique is often used in earrings, pendants, and rings to offer a more affordable alternative to a single, larger diamond. The consistency of the diamonds produced by the Kiel factory is particularly important for cluster settings, as it ensures a uniform and aesthetically pleasing appearance.
The “SI1+” clarity grading makes these diamonds suitable for a wide range of jewelry styles, providing a balance between affordability and beauty. The inclusions are minor and generally not visible to the naked eye, ensuring that the diamonds retain their brilliance and sparkle. The factory’s rigorous quality control processes ensure that only diamonds meeting the SI1+ standard are offered to customers.
The “G+” color grading places these diamonds in the near-colorless range, meaning they exhibit only faint traces of color. This ensures that the diamonds have a bright, white appearance and will complement any metal setting, whether it be white gold, yellow gold, or platinum. The near-colorless nature of these diamonds also makes them versatile and suitable for use in a variety of jewelry designs.
The Kiel factory’s products are also relevant to the lab-grown diamond market. Lab-grown diamonds are increasingly popular and the factory could expand to include the manufacturing of lab-grown diamonds to cater to a wider range of customer preferences.
The factory also has the option to offer a variety of diamond shapes besides the round brilliant cut. They could produce princess cuts, emerald cuts, oval cuts, and more.
