Hi Staceyjan,
I think most ladies share the same sentiment - purchasing your first starter piece will start you on a love affair with VCA.
My thoughts - my suggestions for your first starter piece will depend on your current budget. If your budget is on the higher end, I would go for pave earrings, or a pave pendant. I think the Alhambra Pave earclips in otherwise WG or YG would be a great first piece. If pave is not a consideration at this point in time, I would consider the vintage Alhambra earrings, or even the Magic size. The colour and gold will depend on your colouring. I would suggest work with a great SA that does not pressure you, and will allow you to try on pieces as often as you need. I am in the process of deciding on my next purchase and I have seen/emailed my SA a few times/week for the last three weeks and I still have not decided on anything. VCA is an expensive purchase which you hope will last a lifetime so it is not a decision that should be made lightly. Good luck!
