My favourite reference for precious metal price history is Goldprice.org. For the past 10 years, the price movement as in USD per ounce (or 28.35 g) is as follows.

If you look at the price at 27 Dec 2017, which is near USD 1300 per ounce. The price at USD per g is USD 45.85 per g. In Singapore dollar, that is SGD 61.43 per g. All jewelry shops in Singapore are displaying gold price as ~ SGD 60 per g.
