Need advise on gemstones

Hi, I came across this forum and saw great advises from expert astrologers, thought i would post my issues, hoping to get some help

My DOB: Dec 8, 1977

TOB: 7:47pm

I am facing some challenges and co-incidentally consulted 3 astrologers (through a friend and family member), and got the below opinions; but i feel something is still blocking me and i am not seeing progress

Astrologer 1 suggested below

1. Amethyst on right hand middle finger in silver ring (insisted not to wear blue sapphire as its a risky stone)

2. Yellow sapphire on right hand index finger in silver ring

Astrologer 2 suggested below:

1. Blue sapphire with diamond or zircon (in one ring) on right hand middle finger made in gold or panch datu

2. Emerald on right hand little finger made in gold or panch datu

3. OR wear a pendant that contains all 3 stones – blue sapphire, zircon (or diamond), emerald made in gold or panch datu 

4. Also mentioned, till i can afford purchasing gemstones, wear an IRON ring in right hand middle finger so start seeing positivity

Astrologer 3 suggested below:

1. Blue sapphire on LEFT HAND middle finger in gold or silver

2. Emerald on RING finger in gold or silver

I understand i should be trusting and following one person whom i trust. And i want to trust Astrologer 2 from my discussion with him. There are some commonalities amongst these astrologers suggestions. But since i have now consulted more than one astrologers, please advise me with corrections.

Can you also please advise me,

1. if i can wear Amethyst (Blue sapphire being expensive) with Emerald?

2. What could be the benefit of Zircon as suggested above?

3. Do i still have to wear yellow sapphire, after i start wearing blue sapphire or amethyst, emerald, zircon?
