9ct gold clasp for dragonscale

[Mikael Johannesen]

Hi.

I'm planning to make a 9ct gold dragonscale bracelet for a client. Currently i'm making a mock version with silverplated copper to get an idea of the size and amount of wire needed.
I love the slide / tube clasp for the dragonscale weave however i cannot find a pure gold version of it.

The closest i've found is this
9ct Yellow 3 Row Rectangular Bracelet Slide Clasp, 3 X 16mm

Would that clasp be durable enough to secure the bracelet?
The weight is almost 400 grams in gold by my current estimates.

In the picture i've sized the caliper to the size of the clasp and showing a smaller dragonscale with a tube clasp.
