hi JGal,
I think in modern days, it is gal who keeps sdj. cos during olden times, when gal marries guy, everything gal has belongs to guy and his parents. So in thoery, sdj belongs to guy's parents..These days, Ithink it depends on whether the gal is being seen as "sold" away by her parents (ie. many tables or huge pinjing retained by bride's parents).
During tea ceremony, gal will usually be given jewelry from relatives, includng mother and MIL... I think it's a nice gesture to wear the jewelry on the spot. If possible, just wear everything loh.... Usually, gal will be expected to wear the jewelry the guy's parents/relatives give her during her tea ceremony at the guy's parents' home... when she returns to her own home, so that she can show her parents the "gifts".
