You can attract the person you want to marry by wearing a love ring on the thrid finger of your left hand.
To start, use your lover's Sun sign to aquire the stone from this list:
Aries: Bloodstone
Taurus: Saphhire
Gemini: Agate
Cancer: emerald
Leo: Onyx
Virgo: Carnelian
Libra: Peridot
Scorpio: Aquamarine
Sagittarius: Topaz
Capricorn: Ruby
Aquarius: Garnet
Pisces: Amathyst
Bring the stone to a jewlar and have it set into a gold band. (this can be expensive and inconvenet for some, if this is not possible you can buy a gold ring that is already set with the needed stone)
Then note the changes that occur you begin wearing the ring.
If the stone changes the weaer into the kind of person you can attract and hold love interest then it will bring the relationship to you. If the band hurts or the stone falls out, the relationship will be difficult. If the ring fits perfectly and stays put, exdpect your lover to wind rings of love around you.
