What do you crochet with?
I mostly use tuff-cord because it is more durable to wear and tear than silk. Neckstrings are not delicate, and the only time I have ever had one break is when one of the tips got stuck in something--like bending over a wrought iron table or something. I often crochet chain with thread which increases the strength even more and is great for heavier or more rough cut, heavy stones.
What is Gold Fill & Gold Vermeil versus Gold Plate?
Gold Fill and vermeil are wonderful affordable alternatives to 14k gold which is why i use them. Gold-filled jewelry has 100x more gold alloy than gold plated and because that layer is so much thicker, it means gold-filled jewelry lasts longer and stands up to wear and tear better than gold plated.
Instead of being dipped in gold, Gold Filled jewelry undergoes a mechanical bonding process that melts a thicker layer of gold onto the base metal. By law, gold filled jewelry must contain 5% gold by weight to be categorized as such. Gold Plate has less than 1% gold content and may have initial luster but fades and is easily rubbed off.
Gold Vermeil is a common type of gold plating, which uses sterling silver as the base metal. Vermeil is more hypoallergenic and has a thicker layer of gold than normal gold plating, which is why you'll see it in stores selling fine jewelry.
