I've just picked these up from the office and I'm so happy with them! they're all so beautiful!
They are much better than I was expecting. This is a lot closer to what I saw in my mind's eye.

Now what I was going to do was to make a gold frame for the cabs separately here in London. However, now the supplier says they can manufacture the complete cabochons in the new design solution that I've created. But my issue is that we've tried this before and they broke! Will they be able to do it this time? We shall see.
Meanwhile, I plan to have the plate engraved in the meantime.
Will keep you posted :)
