1. If it is inlaid on a gold setting to make a ring, earrings, pendant, etc., usually the pearl needs to be half-punched, that is, the hole is punched but not pierced. If you are stringing a whole pearl necklace or wearing it as a whole chain with other accessories, you need the pearl to have a pierced hole, which is the full hole mentioned above.
By the way, due to the irreversibility of punching, any punching will reduce the value of the pearl itself (only the pearl itself, and please distinguish the value and price), especially the larger precious variety pearls. Therefore, the precious pearls in general pearl shops are all in an unperforated state, and half-holes are rarely in stock. Of course, it doesn’t matter if they are cheap or have been sold as finished products.
Simply put, undrilled holes can be made into half holes, and half holes can also be expanded into full holes, but due to the natural nature of pearls, you cannot turn the full hole into half holes, so once punched, it cannot be restored.
2. Inlaying or stringing necklaces does require some craftsmanship, but it is not a job that requires very professional skills. As long as you have the skills of ordinary people, it is enough. There are many DIYers.
What is Lorem Ipsum?
Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.
Why do we use it?
It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout. The point of using Lorem Ipsum is that it has a more-or-less normal distribution of letters, as opposed to using 'Content here, content here', making it look like readable English. Many desktop publishing packages and web page editors now use Lorem Ipsum as their default model text, and a search for 'lorem ipsum' will uncover many web sites still in their infancy. Various versions have evolved over the years, sometimes by accident, sometimes on purpose (injected humour and the like).
