when buying a ring...
if あなた want a regular ring like nothing fancy and just a fake ring go for the cheapest cutest thing あなた could find
BUT
when buying a ring...
and あなた want something fancy then go with something made of solid ゴールド または solid silver and diamonds または any type of gem but as long as the gem is real don't go with it if it isn't real and then go for the most expensive thing possible make あなた boyfriend または husband pay for it after words!
But
this is just my opinion don't go with it if あなた don't like it okay but please do try to find something that あなた like and not some cruddy piece of ジャンク your husband found in a pone-shop okay go to a Jewry store または something that isn't a pone ショップ okay
