During valentines day my partner gifted me a necklace. It contains a golden chain (not real gold) and a round square slate of rose quarts. I dont know where he got it or bought it from but the second i put it around my neck i could feel that something about it was off. Even after cleansing it with incense i feel like im being choked. It dosent weight much but it feels as if i were a dog being walked with a massive chain. I feel anxious when wearing it. Since it was a gift from him i really want to wear it but everything in me tells me not to. The energy it has is sickening and i dont know what to do.
Any help or advice is appreciated!
