What is the star system?
The star system calculates the number of pieces that were handled by Conchology, Inc. in the last 21 years:
| 0 – 5 pieces | 6 stars |
|
| 6 – 10 pieces | 5 stars |
|
| 11 - 25 pieces | 4 stars | |
| 26 - 75 pieces | 3 stars | |
| 76 - 150 pieces | 2 stars | |
| > 150 pieces | 1 star | |
We want to point out that the star system is only very reliable for PHILIPPINE shells only, as we handle very few foreign shells in general. As time goes, the system will become more and more performant.

ANCONA, CESARE D' (1832â-1901), Italian geologist. D'Ancona was born in Pisa and studied geology under Meneghini. He was appointed professor of paleontology at the University of Florence in 1874. D'Ancona reorganized the section of tertiary malacology of the Central Italian Collection of Paleontology over a period of several years, and as a result, the Italian Geological Committee asked him to prepare a comprehensive, systematic survey of the malacology of the Italian pliocene and early quaternary. This survey, the first since the early study of G.B. Brocchi in 1808, was published in 1871â73 and became the standard work on the subject. - Edit
