My raw blue turquoise crystal nugget hoop earrings have been carefully handcrafted in sterling silver.They feature raw, genuine turquoise crystals that dangle from the hoop earrings.About turquoise: - Turquoise is an age-old stone and was seen as a symbol of wealth in ancient cultures. - It is the stone of protection. - It represents wisdom, tranquillity, friendship, love, strength and protection from harm. - Turquoise is the traditional birthstone of December, the natural birthstone for those born as spring begins (20th March to 19th April) and is the Zodiac Stone of Sagittarius (22nd November to 21st December).Crystals have inclusions, which appear naturally in gemstones. Sometimes they can be accidentally mistaken as cracks, but they're actually minerals that have been trapped within the crystal as it has grown. Inclusions are perfectly natural and make each individual crystal unique. They're part of the crystal's natural beauty and history.
