  • Sandro Dreher

    Ich kaufe nun schon seit vielen Jahren bei OFM. Ich bestelle jetzt regelmäßig hier, weil ich sicher sein kann, dass ich das bekomme, was ich bestellt habe. Und das Beste ist, dass sie auf meine Wünsche eingehen. Bisher habe ich immer einen wirklich schönen Rohopal zu einem sehr guten Preis erhalten. Deshalb bin ich so froh, diese Seite gefunden zu haben, und ich bin mir ziemlich sicher, dass sie einer der besten Opalhändler ist. Vielen Dank für alles.

Pictures coming soon of finished pieces!!!
