Worth knowing
SSEF is a non-profit foundation under Swiss law; the abbreviation stands for Schweizerische Stiftung fuer Edelstein-Forschung. The institute states that origin determination is an expert opinion, and that online verification of a report at myssef.ch is required to establish that the report is valid.

We verify dealers, not stones. A laboratory report describes one stone on one date; it is not a guarantee of value, and it is not ours to stand behind.
