A friend has asked me to make a pair of stud earrings for her using two small (5mm) garnets she has supplied which are in a ring, she does not want the ring. She wants the earrings to be made using yellow gold and she has given me a small cross (which she has been told is gold) to melt and turn into wire for for the earrings.
She does not think the ring is gold, however I scratched both the ring and the cross on unglazed ceramic and both had gold colored scratches that look the same as the scratch from a known 14K gold piece.
The cross has no hallmarks, the ring has two: 1) a rabbits head with a “3” next to it, and 2) a “G1” mark. Some googling suggests the ring is a Czeck production and the rabbit’s head with a “3” means .9 silver, but the ring is clearly gold colored, so maybe plated ?
I’m going to assume that I will not know the karat of the gold cross. Any advice here ?
The earrings I will be making, I have made in sterling several times and always go through hard,medium and easy solder. Is this the same procedure I should follow for the gold soldering steps? Also, should I use the lowest karat gold solder I can get in case the gold piece is a lower karat piece. The gold piece she is supplying is sentimental and its important to her to have that gold become the earrings.
Any other advice? I feel like I need to by some gold wire and solder to practice first since I dont want to destroy her gold.
