Jewellery production by the jewellers Franz & Maximilian Hemmerle

From minerals to sparkling gemstones

The elaborate process of producing a breathtaking piece of jewellery starts with a precious stone. Gemstones are generally minerals, formed in a complex and lengthy process far under the earth that may span millions of years. The magnificence of these unique minerals is brought out by the skill of experienced gemstone cutters and polishers. RenéSim works with gemstone dealers from all over the world to source the most desirable stones for you. Our long-standing and trust-based partnerships with the most exclusive mining and cutting companies in the world enable us to offer you the most beautiful quality gemstones currently available on the market at outstanding conditions. We are also happy to use unusual colours or special shapes or styles of cut in making your jewellery dream come true.

Goldsmiths and gemstone setters

The gems are inspected thoroughly by our on-site experts and passed with confidence to our highly-qualified goldsmiths, who create the ring bands and precious items that complement the gems as the perfect setting. Highly trained gemstone setters then set the gems, a task involving special consideration of the unique features of each stone to ensure it sits perfectly and securely in the setting. All our jewellery is produced in Germany by highly professional experienced goldsmiths and setters. We guarantee that each of our exclusive pieces has been produced individually and meticulously by hand using only the finest-quality materials.
