Rare Violins & Bows

When purchasing through TJD, all essential documents, certificates and valuations needed in order to guarantee the instrument’s long-term investment value will be provided as part of our exemplary service. We are proud to provide state-of-the-art condition reports, dendro-chronological reports and CT-Scans on demand as well as complete provenance and history documentations on instruments sold through us. 

A certificate of authenticity issued by a highly regarded international expert is beyond doubt a strong asset to any stringed instrument. We regularly advise our clients in obtaining second or third opinions to update certification according to the latest historical information including the ever-growing technology of scientific analysis in order to regularly revalue the treasures acquired through TJD.   

It is crucial for the item’s long-term value performance to understand the often-ambiguous wording used in certificates. Due to our extensive experience in this field, we provide expert guidance to our clients in every area of certification and valuation. By request, we are happy to issue our own certificates and valuations for items, whose maker can be identified with certainty. Furthermore, we are pleased to supply our buyers with complementary insurance valuations every three years as part of our comprehensive service. If you wish to inquire about TJD’s certificates and valuations, please contact us by using the contact form or make an appointment.​
