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.
S. ultima new. Like purpurea, smaller, .95 by .40, costa coarser, darker within. Another fine example of recession with four species intervening between it and the species it mimics two of them white!
