It never occured to me how difficult making a stand like that would be, so you did a great job! My only concern is it's a bit 'busy' not a plain background which would make the necklace stand out more (easily fixed by draping a plain cloth over the shoulders.) It looked black and white to me in that light so I'm glad you said it is purple and white which I like more :)
I think it's amazing that you're doing woodwork as well as jewellery making! ♥
