How can I transfer or gift 800 grams of gold to my daughters?

ET Wealth Reader's Query: I am a 50-year-old widower. My wife passed away a few years ago. I currently have around 800 grams of gold that belonged to her and my late mother, combined. I have two daughters, aged 12 and 13. I would like to understand how I can transfer or gift this gold to my children. I do not have the purchase invoices for the gold.
