Hessonite and Pearl has no connection in speeding up your marriage.
For your concerns, I would recommend you to wear the following gemstones.
1. Natural Jyotish Yellow Sapphire (3.5 to 5 carats) in Gold/Silver setting in Left Index finger.
2. Natural Jyotish Red Coral (4.5 to 6 carats) in Gold/Silver setting in Right Ring finger.
Are you wearing any other gemstones? Please let me know.
I wish you good luck in implementing Planetary Gemstone Therapy.
