I have two of your marvellous rings. One a simple gold oval large right that I wear daily and get many compliments and a y second my late husband Gunter, bought me. A rectangular gold right with small diamonds and rubies and a large band, that needs enlarging. If you receive this message, maybe could you respond ?

I think Schluep’s work should be so much better known than it is. Would love to see photos of your rings!
