If you ever get to Istanbul, you have to go to the Grand Bazaar. It must be one of the 7 shopping wonders of the world, with over 4,000 shops.
I spent ages in one jewellery shop agonizing over what to buy. Sadly, I couldn't buy the lot, but chose this necklace and a few other treasures.
The necklace features delicate, amethyst teardrops. These are suspended on a string of small amethyst pieces and accented by tiny metal beads throughout—the many shades of purple shimmer and shift in the light, it's a stunning effect.
