KUK HOF-U. KAMMER -JUWELIER U. GOLDSCHMIED AEKÖCHERT SEIT 1814 Examination outcomes of the “Florence Ruby” on October 21, 2025. The “Florence Ruby” hangs, which indicates that it was gotten rid of from its setup eventually in the past. The hatpin on which it was established has actually been maintained in 4 pieces: initially its setup, right into which the gems fits, and after that 3 different get rid of old-cut rubies. As soon as constructed, the 4 components correspond the historic picture of the hat pin with the “Florentine Ruby” on it. Its weight was established making use of a mobile carat weight range to be 137.17 carat weights (feasible inconsistencies of approximately 0.02 carat weights) – this about concurs with historic resources, which give somewhat various info: 133 carat weights (Kathrin Unterreiner, “Habsburgs Verschollene Schätze”) [The Lost Treasures of the Habsburgs]) and 137.2 carat weights (Wikipedia). “Florence” was verified to be a ruby with the assistance of a digital ruby tester. This gives an action of a ruby’s credibility based upon its thermal conductivity. Its reducing pattern is practically precisely as explained in historic resources. Every one of this persuaded me that this was a real, historical “Florentine ruby.” Below is a recap of the variables that led me to this final thought: 1. The rock matches its setup. 2. Its weight is 137.17 carat weights, which follows historic information. 3. Verify the credibility of their rubies with ideal digital devices. 4. Its editing and enhancing follows historic information.
