JNA Award for KS Jewelry International for Industry Innovation of the year

Founded in 1979

by the visionary brothers Klaus and Michael Stenzhorn, our company embarked on a transformative journey that would redefine the standards of jewelry production. Initially, they focused on wholesale, supplying jewelers in Germany with merchandise crafted by local manufacturers in Bangkok. While successful in sales, our founders, driven by a relentless pursuit of excellence, sought more consistent and higher-quality products.

In the mid-80s, the Stenzhorn brothers made a strategic and challenging move to establish their production in Bangkok. This decision was driven by a vision to match the quality of top European factories. Their unwavering perseverance in the face of challenges led to significant improvements in all aspects of the production.

At that time, Bangkok's jewelry manufacturing landscape primarily catered to the lower end of the market. Undeterred, Klaus and Michael took bold steps to elevate their craftsmanship by inviting esteemed specialists from Europe to train their local staff. Introducing microscopes for pavé setting marked a significant milestone in the setting section, quality control, and all goldsmith benches. Their determination knew no bounds.

Having successfully achieved European-level quality in Thailand, the brothers were not content to rest on their laurels. They felt compelled to push the boundaries further, pioneering the creation of intricately invisibly set pieces adorned with diamonds. This innovative approach, a testament to our commitment to pushing the boundaries of creativity, set new benchmarks in the industry. Additionally, K.S. Jewelry developed a unique technique for crafting flexible necklaces and bracelets, using coronets meticulously handmade from pulled wire.

Our creations' exceptional craftsmanship and unparalleled quality have not only caught the attention of prominent brands but have also led to exclusive and fruitful business relationships. Our commitment to excellence and innovation has been recognized by the industry, leading us to acquire gold and diamond mines in Africa and, subsequently, a diamond-cutting facility in Santo Domingo.
These achievements stand as a testament to our unwavering dedication to excellence and ability to deliver on our promises.

Today, K.S. Jewelry is celebrated within the jewelry industry for several unique techniques, each resulting from our expert engineering, state-of-the-art technology, and the marriage of high quality handiwork. Our unwavering dedication to excellence continues to propel us forward as we embrace
innovation and strive to redefine the artistry of fine jewelry
