Hi Izzy, yes still loving my WG necklace & bracelet! For me, the combinations that 10 + 5 allows is perfect; I don't think I would want or need a 20 motif at all.
One thing to consider is the weight. My 10 motif all WG weighs 37g and my 20 motif MOP weighs 52g. Whilst it may not sound or feel much when picked up by hand, you do notice the difference when it is around your neck! Try out the YG or RG versions in store if you can.
I often wear the necklace with my WG pave earrings, which is as blingy as I get. They look great together.
If you're considering other 'off the shelf' purchases, I do tend to wear my 20 WG chalcedony more often than the MOP one. I absolutely love it, the colour & striations are beautiful.
Now just need to convince DH to buy me the single row perlee bangle! Judging by one of the other threads, I'm not the only one to fall in love with that piece. I've been a very good girl, honest!
