I call this necklace a Chakra Drop Necklace. Its main body is made up of Green Aventurine with quartz, amethyst, aquamarine, zoisite, citrine, smoky quartz, and onyx drops.
Green Aventurine is known as the "Stone of Opportunity" thought to be the luckiest of all crystals, especially in manifesting prosperity and wealth or for increasing favor in competitions or games of chance. It's winning energy makes it a great ally for boosting one's chances in any situation - a first date, a tax audit, or even landing a promotion. One needs only to be near it to derive its benefits.
