Citrine Pendant How Much Is This Jewelry Worth And Should I Even Sell It?

How much is this jewelry worth and should I even sell it? - citrine pendant

I have jewelry, I think, Sales / Business. Most of my songs or not, and never used or not (a counterpart to the other is gone, etc.) or rocks.
The jewelry includes
1 24kt Gold 1/4ct Diamond Stud
1 14k Gold 1/5ct Diamond Stud
1 loose 1 / 4 ct flawless citrine
1 Not opal white gold 14 carats
1 Trailer in 14 carat gold with 1 / 5 ct Aquamarine

If I sell them I would bring money into savings or use to pay my credit card.
Can someone tell me what would be a good sum of these items worth? Should I sell or keep myself? More value is its value as jewelry or monetary policy?
