Vintage 14k bicolor yellow and white gold snake chain, 16 inches long and 1 mm wide, solid gold (not plated), hallmarked 14k. The main color is white gold, with diamond-cut yellow gold sections and yellow gold lobster clasp. Unsure the exact age, but more than 20 years old as I received this as a gift while visiting Hawaii. Very good vintage condition, recently cleaned and polished. I switched to yellow gold about a decade ago, so I hope this beautiful necklace will go to someone who looks good in white gold. Please let me know if you have any questions or would like other photos. Note: I do not sell as a job and do not own calipers, so I cannot give a more precise width measurement than whole numbers in mm using a measuring tape. I cannot specify if a chain is 0.8 mm, for example.
