Updated editions of all Blue Books of gemmological standards and nomenclature on CIBJO website

The six CIBJO Blue Books are definitive sets of grading standards and nomenclature for diamonds, coloured gemstones, pearls, coral, precious metals, and gemmological laboratories. They are compiled and then are consistently reviewed and updated by the relevant CIBJO Commissions, whose members include representatives of trade organisations and laboratories active in the respective areas of the industry. In the almost complete absence of jewellery industry standards endorsed by the International Standards Organisation (ISO), the CIBJO Blue Books are the most widely accepted set of globally accepted standards.

The updated versions can be downloaded from the following page on the CIBJO website: http://www.cibjo.org/introduction-to-the-blue-books/.

For individuals who are not members of a CIBJO-member organisation, each individual download will cost 9.90 Swiss francs. All six Blue Books (Diamond Book, Gemstone Book, Pearl Book, Coral Book, Precious Metals Book and Gemmological Laboratories Book) can be downloaded as a single package at a discounted rate of 49.90 Swiss francs. For individuals who are members of an organisation that belongs to CIBJO, he or she is entitled to receive the CIBJO Blue Books free of charge. They should contact the organisation of which they are members to arrange delivery of the relevant Blue Books by email.

Curso: Introdução à Gemologia

Curso Maria José Trindade

A Maria José Trindade, que organiza e lecciona o curso, é uma gemóloga com uma rara base científica, garantia da qualidade dos cursos que lecciona. Para se inscrever no curso de Introdução à Gemologia do próximo dia 9 de Julho (em Lisboa) basta aceder ao site da WeValue: Formação Avançada.

Maria José Trindade graduated in Geology (Faculty of Sciences of the University of Lisbon), also has a Master degree in Dynamic Geology (Faculty of Sciences of the University of Lisbon) and a PhD degree in Geosciences (University of Aveiro). She also has a specialization in Gemology and Diamond Grading (Portuguese Gemological Institute).

She has scientific experience in different areas, such as geochemistry, mineralogy, igneous petrology, volcanology, sedimentary basin analysis, clay deposits, external geodynamics, archaeometry, weathering of stone built heritage and compositional characterization of historic tiles. More recently, she obtained experience in the study of gemstone’s properties used for their identification and separation from fakes (synthetic and artificial substances).

Her professional activities, as a FCT post-doctoral researcher, have been developed in the Center for Nuclear Sciences and Technologies (Nuclear and Technological Campus of Technical Superior Institute) and she also collaborates with Geobiotec research center (University of Aveiro). Her work has been dedicated to the application of nuclear methods and mineralogical analysis to characterize geologic and ceramic samples in studies regarding distribution of trace elements and natural radionuclides (U, Th and K) in superficial environments, as well as in provenance studies of archaeological shards and cultural heritage studies.

She is author of several scientific papers in national and international journals and proceedings of scientific meetings, in addition to dozens of oral and poster presentations in international and national conferences, in a few as invited lecturer. She was awarded as “best poster” and “young investigator” in two European scientific meetings. She is also a reviewer of scientific papers and was a member of the scientific committee of a congress and a symposium held in Lisbon.  

Rubies from Mozambique – Field report published by GIA

I have had some involvement with mineral projects in Mozambique; I follow with attention news, especially on tantalum, diamonds – Diamonds discovered in Mozambique – Mustang Resources’ Save Project, coal – and rubies – Montepuez’ GEMFIELDS rubi mine – newest updates on the world’s single largest ruby and corundum deposit.

I have just came across an excellent GIA field report on the Mozambican Montepuez ruby mine, originally published at the 2015 Spring issue of GEMS & GEMOLOGY.

Enjoy.

Montepuez’ GEMFIELDS rubi mine – newest updates on the world’s single largest ruby and corundum deposit

Discovered in 2009, Montepuez (Mozambique) is the world’s single largest ruby and corundum deposit. GEMFIELDS acquired a 75% interest in the concession in June 2011 from Mwiriti Lda. Montepuez Ruby Mining Lda (“MRM”) is the project operator and a joint venture between Gemfields and Mwiriti Lda. GEMFIEDLS released two documents on Montepuez by SRK Consulting.

According to the Reserves and Resources presentation:

  • 16 million carats (“mct”) produced to date.
  • To date a total of USD55 million has been invested , generating current total revenue of USD122 million.
