These splendidly embedded Natural Emerald Stud Earrings showcase an AA quality round Natural Emerald each four prongs set in 18K Yellow Gold. Approximate Gemstone Weight: 0.61-0.95 Carats. Plush earrings to give a royal touch to every outfit. The emeralds are graded AA by our graduate gemologists. AA graded emeralds have a very nice color tone to them, and are opaque to slightly transparent with a little bit of crystal. All emeralds are oiled as a common practice in the trade, and is accepted by all reputed jewelers. We do not carry any emeralds with treatments that include resins, glass, and plastic polymers that are melted into the gem. These are typically used for emeralds with extreme durability issues, as the fillers also work as binding agents. This is NOT industry standard, and MUST be disclosed at time of sale.,METAL:18K Gold,ACTUAL METAL:18K Yellow Gold,BACKING:Push Backs,WIDTH:5 mm,LENGTH:5 mm,GEMSTONE:Natural Emerald,SHAPE:Round,AVERAGE COLOR:Medium Green,AVERAGE QUALITY:AA,MINIMUM CARAT TOTAL WEIGHT:0.61-0.95,GEMSTONE DIMENSIONS:5 mm,SETTING STYLE:Prong Setting,NUMBER OF STONES:2,COLOR:Green,PRODUCT TYPE:Stud Earrings,GENDER:Womens,MATERIAL:Gemstone,TREATMENT METHOD:Oiled,STONE CREATION METHOD:Natural
