JAENSCH follows a vision that takes advantage of combining the technological developments that are transforming today’s diamond and precious gemstone industry with the ease and efficacity of modern user-friendly online retail. This value proposition is achieved by buying select rough, preferably at the source, and manufacturing it under my supervision or whenever necessary acquiring select polished stones. These beautiful gems are then offered to the world directly or arranged to create wonderful jewels masterly crafted under my supervision.

Vertical integration enables the company to eliminate traditional layers of intermediaries which at best add only limited value, thereby shortening the supply chain. E-commerce through this website combined with a cost-efficient structure enables the company to offer items at close-to-wholesale prices to the discerning public, a time-and-again winning approach in today’s high-end consumer-led luxury market.

A broad selection of exquisite diamonds and precious stones awaits you, ready to be set in bespoke jewellery destined to adorn you! All diamonds and precious stones offered on the website are natural, unique and conflict-free.

Should you have any questions, please feel free to contact me via the contact form below. Alternatively, if you would like to arrange a personal appointment feel free to call or email me at any time.

You are welcome for viewings of items above 1500 Eur. Viewings are currently by appointment only. Jewellers and retailers welcome!
