Hi, I recently bought this necklace and am very curious about the turquoise and the overall value of the necklace. Also, the hallmark is not one that I’m familiar with so any help with that would be appreciated too. The necklace is long and measures 16 1/4” from clasp to the bottom of the pendant. It weighs 97.14 grams. The turquoise is a beautiful blue with a matrix that ranges from chocolate to caramel. The stone measures approximately 7.5 cm by 4 cm. The hallmark is not stamped but formed with wire which has been soldered to the back.
My questions are:
- Is the turquoise Royston and about how many carats?
- does anyone recognize the hallmark? Is it NA or Anglo?
3)An appropriate value if possible.
Thanks for your help!
