Give enough time to meet those special occasions as stocks run low at Christmas etc.
Gold jewellery is made out of gold alloyed with other metals - it is specified as a carat number.
The carat number specifies the amount of gold in the alloy. It can also be marked as 375 or 750. The color and appearance of gold jewellery is the same irrespective of the carat number. Gold is basically valued according to its weight and design does not alter the value much. Make sure that the jewellery is solid gold - i.e. you can buy hollow gold or jewellery chains which are made of hollow tubes which can be dented and are very difficult to repair.
