These are earrings made of Sterling Silver, a high-quality metal. The earrings are polished to give them a shiny finish. The design features cute dolphins made of silver and decorated with green emerald stones and small diamonds. 20 emerald stones, a green gemstone, are prong set in each earring along with 2 small natural diamonds. The earrings are complete with all the stones included, and are solidly made. The earrings are made for women and have a button design that fastens securely with post and push back closures. The emeralds in the earrings have been treated with oiling/resin for added beauty. This makes a great gift choice for anyone born in May, as emerald is the May birthstone.Material: Primary - Purity: 925Finish: PolishedStone Type 1: EmeraldStone Type 2: Natural DiamondStone Color 1: GreenStone Quantity 1: 20Length of Item: 14 mmStone Setting 1: Prong SetStone Weight 1: 0.01 ctStone Weight 2: 0.010 ctFeature: SolidManufacturing Process: CastedMaterial: Primary: Sterling SilverCompleteness: Complete (all stones included)Stone Shape 1: RoundStone Size 1: 1.4 mmStone Treatment 1: Oiling/ResinItem Weight U/M: gmWidth of Item: 12 mmProduct Type: JewelryJewelry Type: EarringsSold By Unit: PairGender: Women'sMaterial: Primary - Color: WhiteEarring Closure: Post & Push BackEarring Type: ButtonStone Creation Method 1: NaturalStone Creation Method 2: NaturalBirthstone Month: (05) MayEarring Back Type: FrictionEarring Style: Birthstone
