The dolphin symbolizes wisdom, gentleness, intelligence, good luck, and protection. Known as friends to humans, the crystal dolphin necklace depicts a baby dolphin and mama dolphin surfing joyfully, with waves forming a crescent moon engraved with "I love you forever." The pendant measures 1.10 by 1.04 inches, with an 18-inch chain and a 2-inch extension for adjustable sizing to fit most women. Made of 925 sterling silver, it is hypoallergenic and passes any quality test. This dolphin jewelry set includes one necklace and one gift box, making it a perfect present for moms, grandmothers, wives, girlfriends, or best friends on birthdays, Christmas, Valentine's Day, Mother's Day, or any special occasion. Over time, silver jewelry may oxidize and darken. To restore its shine, gently clean it with toothpaste.
