Wedding Gift To Sister

My sister planning to get marry on coming year, and being one of her sister. I'm starts to thinking of what kind of wedding present should I really for her. We usually will give cash money to the couple, just like what my elder sister gave me. But this time I wish to give her something nicer, no one of our family members are single after she get marry. So being the final benefitiance, she definitely will get a VALUE wedding gift from us.

I'm thinking of buy some gold as her wedding gift, since gold are valuable. And I think I won't go for gold jewelry but will investing into gold bars or god bullion. My objective is to buy and hold for my sister. I think the price of gold sure will increase again in future. Now never be the good time to invest into gold. OK..will discuss with my others family members, If all of agree then we will buy in as many as possible as sis's wedding gift. Of cause within our budget. :p
