I purchased these last year and used them about three times. I had them cleaned at a jewelry shop before listing them for sale. They are a very cute single-stone pair of ear rings♡. They will be sent without a case, wrapped in bubble wrap, and shipped via Yu Packet Post Mini. 【Material】K18WG (stamped) 　　　　Diamond 0.05ct x 2 (stamped) 　　　　Piercing genuine product (marked) 【Weight】1.50g 【Size】Approx. 10mm x 6mm
