Independent preparation of expert opinions by generally sworn and court-certified experts
Do you need an objective, independent and transparent expert opinion for probate, guardianship proceedings or customs matters?
The Gemmological Laboratory Austria (GLA) has been providing independent and objective expert opinions for jewelry, precious metals and gemstones since it was founded in 1979. The laboratory, based in the center of Vienna, has been managed since 2006 by MSt.in Adeline Lageder, who enjoys a high reputation in the industry as a sworn and court-certified expert.
The trained FEEG gemologist took over the laboratory from Professor Walter Mican – a renowned Austrian gemologist who developed his own grading system for evaluating gemstones and diamonds. Since then, the GLA has succeeded in establishing itself as an objective authority for Austrian courts, authorities and notaries.
Thanks to the close cooperation with the State Gemstone Museum of the Natural History Museum in Vienna and the constant exchange with international laboratories and gemmologists, numerous renowned auction houses, gemstone dealers, insurance companies and financial institutions also rely on the excellent quality of the expert opinions of the Gemmological Laboratory Austria.
Objective, independent, transparent
Accurate and trustworthy appraisals by certified and recognized court experts are becoming increasingly important. The GLA works independently and without conflicts of interest, as it neither buys nor sells jewels, jewelry or diamonds.
Regular recertifications of the court experts, which take place every five years, ensure the high level of professional competence of the experts in the long term. As a sworn and court-certified expert, the head of the Gemmologisches Labor Austria is liable for the expert opinions issued, which offers additional security for customers.
Do you need a second opinion?
If you need a second opinion or additional examinations – especially for rare or valuable stones – we will be happy to assist you with our experience. If necessary, we also work with international experts at home and abroad who specialize in individual gemstones.
Our appraisals include size, purity, color and cut of gemstones as well as possible treatments. We also determine whether the stone is of natural origin or has been synthetically produced. At the customer’s request, the appraisal can be carried out with or without a valuation.
Our offer is aimed at:
- Courts and notaries who handle probate and guardianship reports
- Authorities such as customs offices that determine customs values at EU borders
For probate or guardianship proceedings, we offer particularly short waiting times for the necessary expert opinions. The expert opinion is usually sent in written form within four to five working days or earlier by arrangement if the matter is very urgent.
