If "imitation is the sincerest form of flattery" I would feel proud that of all the designs they produce, yours was one they wanted to offer as an exemple of excellent design, craftmanship and beauty. You will always have the "original".
On the other hand, you do lose some of the "exclusivity" of having the only one.
So, share the beauty with others? or keep the uniquiness and exclusivity for your "one and only" love?
Tough call, one that only you can make.
Regardless of your decision, I would be flattered and proud of the recognition for all the work that went into this beautiful ring design. I'm happy you shared your pictures with all of us here on PS.
