Yes I have 18k overlay singapores for many years now.
I am wearing Technibond that I purchased over 20 plus years ago, and it looks like new. It's my favorite.

Technibond is a trade name for jewelry sold on a television shopping channel. It is similar to the term "vermeil" in which a layer of karat precious metal is bonded onto another metal, usually sterling silver. The precious metal can be such as platinum, or 18 karat gold for example. This is not the same as "plated" with a precious metal. It is a bonding technique.
Technibond jewelry (sold by HSN) is plated/bonded with 14kt. The base metal is sterling silver. From what I understand the process HSN uses is somewhere between gold-plated and a true vermeil. Vermeil is gold over sterling, but the layer of gold is thicker than just goldplating (and more expensive). I think the vermeil process is different as well. I have several Technibond pieces. I like them and they are holding up well.
Mine does!

Silver jewelry may turn pink if the jewelry is fake. This because the outer coating has been peeled away due to wear and tear. Fake jewelry may also turn a person's skin green.
Yes
the jewelry oxidizes when it gets wet. Like copper does when its outside.
Silvertone jewelry is a costume jewelry made to look like silver. It can cause skin to turn green due to the copper and nickel in the metal
