The answer to this question is yes and no, and I'm going to explain in detail why. When it comes to the mineral kingdom there are thousands of different Crystals and Stones. The ones used to make jewelry can be differentiated in there are two main categories, for those who may be new to this information. The first category are known as Precious Gemstones and the second category as Semi-precious ones. Precious gemstones are Crystals such as Ruby, Emerald, Sapphire, Tanzanite, just to name a few.
These Crystals can be very pricey, as they are considered the most valuable. However it is a great demand and desire for these Crystals, which is the reason that created the demand to make them more available at a much lower cost.
In order to do this many manufacturers creates imitation crystals that are lab created, synthetic or faked in some way. The price for hese "Crystals" of course will be much lower. The same applies to Semi-precious Stones, these can be less costly but if they are real, their true value will be definitely reflected on the price, so don't expect to buy a genuine Aquamarine or Chrysocolla piece of jewelry for under $10.
When it comes to buying Jewelry, I have always believed in a rule of thumb, and that is simply that "you get what you paid for."
There are people that wants to purchase a genuine Turquoise piece of jewelry but don't want to pay it's value. I have had many contacting me asking me why my turquoise jewelry is so "expensive" compared to others stores. They're referring to stores they found on eBay or Etsy and the simple response to that, is because that turquoise is NOT real or genuine, reason why the price difference. Because real jewelry is priced to reflect the real value of genuine Turquoise and the other is valued according to the much inferior quality of the stone, which is many cases is not even a real turquoise stone but colored Howlite or Magnesite.
Additionally I always suggest people to use their judgement when looking at gemstone jewelry and apply some common sense;-) For example if you are looking to buy a sapphire ring or an emerald pendant and find them on ebay for $30 you need to automatically assume that it is fake, or synthetic or provably lab created. it may look stunning, even quite real, but I assure you a real emerald or ruby ring will never cost you $30
Now, people who are looking to buy Gemstone Jewelry simply for their beautiful appeal and look, many times do not care if the stone is real or not. Other people on the contrary care very much that the Crystals and Stones in their jewelry is real. They are looking not only to have gemstone jewelry that's beautify but because they want to benefit from the metaphysical properties of wearing the stones. In this case it is very important to make sure that the Crystal Healing Jewelry we are buying is real, or we will be throwing our money away while at the same time being scammed by unscrupulous sellers.
One of the reasons why I create educational videos to teach people about all this things, is because as shared in one of my first videos, I was personally scammed when I started working with crystals many years ago. I have created many educational videos showing how to identify real crystals from fake ones, or how to avoid being scammed, you can find these and many other videos here.
