Let me give you an example: 近年では, the prices of gems of the same quality, regardless of coral, ジェイド, ダイヤモンド, ancient jade, エメラルド, red sapphire, alexandrite, 等, have been rising. さらに, with the depletion of mining sources, the rise in gem prices is still obvious.
Buying gems can basically add value, but the most important thing is appreciation! If you buy gems of good quality and cheap, there must be room for value-added; on the contrary, if you buy gems of poor quality and high price, it is of course impossible to add value in the future. したがって, I suggest that you can often communicate with people who play gems to understand yourself; whether the gems you buy are good, whether they are expensive or cheap, the appreciation ability will naturally increase over time, and the gems you bought naturally have room for value-added.
If you are buying gemstones for the purpose of maintaining and increasing their value, you must choose large ones, such as those over carats. The value preservation and appreciation of small gems is of little significance, while broken diamonds and tiny gems, which are just matching stones, have no meaning of value appreciation, because the price difference is not very obvious.
Is it convenient to buy gemstones?
Unless any gem is well-received in the market, the cash exchange rate is slow and the discount is high. If you rush to sell it, you will lose money! したがって, when buying gems, consider whether you like it or not, and do not have the idea of making big money in the short term. If you want to get rid of it, it is recommended to start with friends and relatives and gems. Maybe the value of this gem has increased a lot, and the original jewelry store you bought will get it back at a higher price. But if you are in a hurry to cash out, you can only find pawnshops or online auctions, and most of the prices will disappoint you!
加えて, many businesses now recycle their own products. もちろん, recycling is based on raw materials. This should be psychologically prepared.
