Are these types of investments in physical gold haram or halal

Are the following types of investment in physical gold haram or halal? Or only one of the options is halal? 1. You invest a fixed amount per month for e.g. 1000. Let's say the gold price at that time is 100 per grams which means you got 10 gram gold investment. 2. You will keep on doing this for 12 months and these investments will keep adding up for e.g. 10 gram + 12 gram + 9.56 grams etc. 3. Let's say at the end of 12 months you invested 12000 and gold total becomes 40 grams. Now you have options: **Option1** You can get 40 grams of gold jewellery of your choice + you won't have to pay any jewellery making charges. **Option 2** You will get some cash bonus for e.g. 500 which you can add in your original investment which is 12000 so now total becomes 12500. You buy gold jewellery from that + only pay 50% discount on jewellery making charges.
