Really. Generally speaking, most merchants will not make a fuss about authenticity (mountain materials pretend to be seed materials) because it is unnecessary. Hetian jade ranges from dozens of pieces of material to tens of thousands of pieces. This is a gray area where businesses can have room for operation. Jade is priceless, and it is difficult for beginners to make an accurate judgment on its value. I went to see the studio you mentioned. It sells some low-end goods, which may be sealed with dyeing wax. Appreciation and collection value is not high. If the price is not high, it is harmless for the elderly to buy one or two, and it is meaningless to buy more.
