On a personal note, I love the rough Druzy stones.

Gold Druzy Quartz, elegantly rough and wonderfully sparkly, are spaced with Black Spinel beads.

PS: don't wear this necklace with a scarf or any top that is made from light fabric. The rough stones don't like silky fabrics. This necklace makes jeans and a t-shirt look like your ready for a gala!
