- Some corporate websites created
Tecnoacquisti® has created the website Stime Perizie e Consulenze of Dr. Francesca Fortunato. The world of antique jewelry, precious gems, and minerals is fascinating and full of mystery. It evokes emotions from past eras and is a testament to elegance, charm, and refinement.
By visiting the page www.stimeperizieconsulenze.eu, you can discover all the services of the Gemmological Training Centre, a highly specialized facility in the analysis and recognition of all types of gemological materials and antique jewelry, both natural and synthetic. Thanks to the use of innovative technological instruments and a team of professionals and experts in the field, the Centre is able to provide all types of appraisals and analyses.
Estimates and evaluations are always carried out with the utmost seriousness and accuracy.
Specifically, the areas of study concern some exclusive sectors:
- appraisals and evaluations of precious stones, modern and antique jewelry, gemological materials
- consultations related to estate, judicial, and inheritance matters
- authentication of the hallmark of antique jewelry, coins, and silverware.
- Restoration of antique jewelry, enhancement of gems
- Studies of provenance, processing, and dating
Consulting, appraisals, and restorations
One of the main sectors of consulting and expertise is that of jewelry, often antique, for which it becomes difficult to trace its history, age, and craftsmanship.
These include bracelets, earrings, rings, necklaces, brooches, precious watches, pendants, even from the last century. They are meticulously analyzed by experts who have been working in this field for many years.
Every consultation, precise and careful, is always carried out in compliance with current regulations. Through study and observation, the historical period, type of material, craftsmanship, engravings and their meanings, techniques used for creation, and even economic value are identified.
The next step after analyzing the jewelry is restoration, to make it wearable again or to entrust it to a museum. The techniques used for restoration are cutting-edge and must always take into account the historical period of origin, so that the choice of materials and craftsmanship is perfectly consistent with it. The final result must comply with rules and regulations.
Experts and goldsmiths are able to study an aged piece of jewelry and confirm its period of creation, thanks to a careful analysis of elements such as engravings, logos, symbols, and various types of hallmarks.
For this reason, there is a close collaboration between restorers and the Ministry of Cultural Heritage, which must ensure that all work is carried out with the utmost respect for the rules to enhance the value of the jewelry.
Gemological analysis and embellishment of gemstones
The analysis of gemstones carried out by the Gemmological Training Center allows for the verification of their appearance, purity, rarity, color, luster, and also their value. It often happens that jewelry is enhanced and enriched with different types of gemstones, which not only increase their beauty but also their economic value. The department dedicated to appraisals addresses the evaluation process based on multidisciplinary methodologies, ranging from history to art to technology, in order to provide the necessary information regarding the historical and artistic placement of the piece and its territorial derivation. The Center therefore provides a historical-artistic certificate of the artifact and its authenticity. The statements issued always refer to the UNI regulations (Italian National Unification Body).
Gemstones can also undergo enhancement processes through very specific processing techniques. For example, through chemical and thermal treatments, it is possible to improve the luster of the stone and remove the dullness caused by the passage of time or natural deterioration.
The main techniques used are infiltration and impregnation.
Infiltration involves inserting completely natural and colorless oily liquids into gemstones such as sapphires, emeralds, and rubies through fissures to increase their transparency.
Impregnation, on the other hand, is often used for more porous materials, such as lapis lazuli, to make the surface more homogeneous. It consists of making synthetic substances like plastic or paraffin penetrate into the pores or fissures, and then allowing them to harden. The results obtained are excellent, and the stone returns to being perfect.
All these treatments need to be repeated over time to achieve a lasting effect. They are not excessively costly, but they certainly lower the economic value of the stone, as it has undergone processing.
The studies of origin and processing
The Gemmological Training Centre, thanks to state-of-the-art microscopes and spectrophotometers, is able to identify any type of treatment that the piece has undergone, related to any type of gemological material, whether natural, synthetic, plant-based, or fossil. It should be noted that there are numerous types of gems and precious stones in nature, which form through different processes, and their study therefore differs significantly. One may deal with materials of natural origin, which have formed over the years through natural processes, or of synthetic origin, that is, reproduced by humans to recreate stones that are as identical as possible to those found in nature. The creation of synthetic origin materials is often difficult to distinguish from natural ones, and it requires the eye of experienced personnel and analysis with more than adequate tools. These are complex processes, obtained in the laboratory through meticulous chemical procedures.
Finally, there are gemological materials of fossil origin, or those produced by secretions from animals, such as pearls or amber.
