I believe it's because they use material from China, although they're typically English tea sets.
Aliexpress.com has sets of china for a good price and many to choose from. Dinnerware depot also has fine china sets and Amazon.com has fine china sets at all different price ranges.
I have seen Gucci, Noblie and Llardo porcelain chess sets. There are plenty of mass-produces chess sets on today’s market, since the production of custom and handmade porcelain chess is hardly possible, due to the complexity of the manufacturing process and since a miniature sculpture is first made for each chess piece before the whole set. It is a long and expensive process. There are also several artisans, who make unique and limited chess sets. Noblie Collectibles has a nice collection of exclusive porcelain chess sets. The prices will be high, but the quality is at the highest level.
Franks Nursery probably sources their Nativity sets from various suppliers or manufacturers that specialize in religious decor. The $59 price point may indicate they are made from materials like resin or porcelain. For specific information on where they are sourced, it would be best to contact Franks Nursery directly.
China, Japan and Vietnam
Macy's has an excellent selection of porcelain tea sets for someone looking to buy in person. The best online sources for buying would be either Amazon for someone interested in buying new, eBay for someone interested in buying a set in a vintage or discontinued pattern, or 1stdibs for someone looking to buy an antique set.
If properly packaged anything can be sent in the mail with little fear of breaking. China gift sets are no exception, just be sure to properly package them so they will not shatter.
Porcelain is the highest grade, non staining and wears well, but may chip, but also very expensive. Acrylic dentures are less expensive, may stain with improper maintenance, and are susceptible to abrasion.
yup....
There are 2 dialects in China: Mandarin and Cantonese. Mandarin is more prominent in China. There are also 2 different sets of writing characters. They are: simplified and traditional.
Department stores are the best place to look as they have extensive home-ware departments so you will undoubtedly be able to find something you like within budget. John Lewis and Debenhams are two you could try, and both have their full range online if you would prefer to shop this way. If you wish to go to a specialist shop then Whittards have wonderful porcelain tea sets.
That is called the intersection of the sets.
The most common pieces that make up a porcelain dinnerware set are plates, chargers, side plates, tea plates, salad plates, and tea cups. Sets usually come in increments of four, eight, or twelve of each item.
