Technibond is a brand that is sold on QVC (TV) and is patented. It is simply Gold over sterling jewelry with gemstones. It was extremely popular about 7-10 years ago and is still being sold on QVC shopping channel today. Very sturdy created jewelry. My mother loved it and owed a ton of it but now she has passed and I am selling it off. It is an expensive line and I am not sure if the gemstones are lab created or natural. I know it is real gold and sterling though. Thanks for asking. Sharon
