The Value of Jewelry Is Supported by an Aprpraisal

Why Should I get an Appraisal?

Consulting with an expert appraiser and or gemologist is an important thing to do if you have valuable jewelry.  An appraisal provides a detailed description of the item including metal purity, gram weight, finish, setting, trademark, condition of item, shapes of all diamonds and gemstones with measurements, estimated weights and color/clarity, the determined value and a GIA Graduate Gemologist’s signature with seal.

The American Society of Appraisers (ASA) is the largest multi-discipline organization representing appraisers.The society was founded in 1936 and is one of the eight major appraisal groups that founded The Appraisal Foundation.

The ASA comprises appraisal review and management, valuers of business, gems and jewelry, machinery and technical specialties, personal property and real property. Candidates—who must have a four-year university degree or its equivalent—are eligible for the Accredited Senior Appraiser (ASA) designation after completing the following: five years of documented appraisal experience; testing in their field or specialty; the submission of two appraisal reports to the society's International Board of Examiners for review; successful completion of the Principles of Valuation education program; and successful completion of the 15-hour Uniform Standards of Professional Appraisal Practice (USPAP) course with examination. A lesser level of designation—Accredited Member or AM—requires only two years of documented appraisal experience in addition to all of the other requirements.

An appraisal provides a detailed description of the item including metal purity, gram weight, finish, setting, trademark, condition of item, shapes of all diamonds and gemstones with measurements, estimated weights and color/clarity, the determined value and a GIA Graduate Gemologist’s signature with seal.

Appraisers in the ASA are subject to a mandatory re-accreditation process every five years. To re-certify they must provide proof of professional growth through continuing education, participation in society activities, and the completion of updated USPAP courses. Publishing articles in professional journals and valuation or specialty-related speaking engagements also provide ASA appraisers with re-certification points.

History of Jewelry

Humans have used jewellery for a number of different reasons:

functional, generally to fix clothing or hair in place
as a marker of social status and personal status, as with a wedding ring
as a signifier of some form of affiliation, whether ethnic, religious or social
to provide talismanic protection (in the form of amulets)[4]
as an artistic display
as a carrier or symbol of personal meaning – such as love, mourning, or even luck
Most cultures at some point have had a practice of keeping large amounts of wealth stored in the form of jewellery. Numerous cultures store wedding dowries in the form of jewellery or make jewellery as a means to store or display coins. Alternatively, jewellery has been used as a currency or trade good;[5] an example being the use of slave beads.[6]

Many items of jewellery, such as brooches and buckles, originated as purely functional items, but evolved into decorative items as their functional requirement diminished.

Jewellery can also symbolise group membership (as in the case, of the Christian crucifix or the Jewish Star of David) or status (as in the case of chains of office, or the Western practice of married people wearing wedding rings).

Polymerization degree and Raman identification of ancient glasses used for jewelry, ceramic enamels and mosaics

Abstract

We demonstrate the utility of Raman spectroscopy as a technique for the identification of ancient glasses and enamel coatings of ceramics. As for any silicate glasses, the addition of network modifiers breaks the Si–O linkages and modifies the degree of polymerization and hence the relative intensity of the Si–O bending and stretching modes. We demonstrate empirically that the ratio of these envelopes is well correlated to the glass structure and to the firing technology used. Spectral Qn components assigned to isolated and connected SiO4 vibrational units allow more precise analysis. Selected porcelains, faiences, potteries and glasses representative of the different Asian, Islamic and European production technologies were studied. Modern porcelain enamels are used as compositional references.
