- Les origines ne sont pas certifiées par un laboratoire, elles sont mon opinion gemologique.
- Les photos sont prises à 10X, avec un objectif macro, qui ne sont donc pas vraiment visibles à l'œil nu.
- Les images ne sont pas à l'échelle, c'est pourquoi nous vous donnons les mesures exactes pour vous donner une bonne idée de la taille.
- Les couleurs peuvent sembler différentes selon les paramètres de votre écran.
