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.
Collectables
CASSIDAE
Mainly subtropical and tropical species. When collected, most CASSIDAE are quite clean. Shells often have small growth marks and trawling damages the siphonal canal. An intact siphonal canal or not will often make the difference between FINE and GEM. Their operculae are interesting. Some species live in deep water and are cherished by collectors. Phalium wyvellei has been from northwestern Australia to the collector. Japanese continental shelf dwellers such as Galeodea leucodoma were common at the end of the sixties but are rare and hard to get now. About 130 taxa, including species, subspecies and forms.
