HYDROTHERMAL GEMSTONES

A brief on what lab created hydrothermal gemstones are

Hydro

What are Hydrothermal Gemstones:

Hydrothermal gemstones are synthetic gemstones created in a laboratory using a process that mimics the conditions found in natural hydrothermal environments. These environments involve high temperatures and pressures that facilitate the growth of crystals. Hydrothermal gemstones are made by dissolving the necessary chemical components in a superheated water solution, which is then allowed to cool and crystallize. The resulting gemstones can have the same physical and chemical properties as natural gemstones, but are often more affordable due to their synthetic nature. Some popular hydrothermal gemstones include aquamarine, ruby, and emerald.

How was Hydrothermal Gemstone created:

A fun fact about hydrothermal gemstones is that they were actually first created by accident in the late 1800s. A French chemist named Auguste Verneuil was trying to create synthetic rubies using a flame fusion method, but instead discovered hydrothermal growth when he accidentally dropped a ruby seed crystal into a hydrothermal solution. This led to the development of the hydrothermal growth process, which is now commonly used to create a variety of synthetic gemstones.

How Popular are Hydrothermal Gemstones:

Hydrothermal gemstones are quite popular and widely used in the jewelry industry. They offer a more affordable alternative to natural gemstones, while still retaining the same physical and chemical properties. Hydrothermal gemstones are often difficult to distinguish from natural gemstones, and as a result, they are a popular choice for jewelry designers who want to offer high-quality gems at a more affordable point. Some popular hydrothermal gemstones include aquamarine, emerald, ruby, sapphire, and quartz. However, it's important to note that natural gemstones are still highly prized and sought after, especially for their rarity and uniqueness.

Why Choose Hydrothermal Gemstones:

Hydrothermal gemstones are identical to Natural gemstones when it comes to their physical properties. They look and feel the same and cost a fraction of the amount that their natural counterparts cost. Not only this but they come in much larger sizes than the natural gemstones. A 10+ Carat Hydrothermal gemstone is much easier to find than a Natural gemstone of the same carat weight. Recently Lab Grown Diamonds have gained popularity for various reasons and with them hydrothermal gemstones have gained popularity as well. Their cost

For those reviewers who have high praise for this product, I'll say: good for you!For me, it's a total disappointment--what I received bears no resemblance to the picture. What I've received is larger than expected, but NOT in a good way. I don't know if it's genuine alexandrite, to me, it looks like a clunky piece of glass. If you are considering whether to buy this or not, my suggestion is "NOT!"

Pretty, but no color change and 1 noticeable flaw just off center. Disappointed about the lack of any color shift. Was going to show my crystal/ gemstone obsessed nephew something cool. Don’t mind the flaw as it gives him something to check out with his loupe. Overall, it looks expensive to a 7yr old so will still gift. However, it there is no guaranteed color shift that should be taken out of the descriptor as it’s very misleading.

Although there is a small chip on the point of the stone the color change is awesome. I first checked this stone under the new led lights and it looks the same as under sunlight. When I took it into another room with a lamp, it turned a stunning green. Thank you guys. I will be dealing with you more in the future.

This is a very nice stone, sent it off to get it checked if it’s real this is a extraordinarily low price for the stone, it does appear to be real. But the size of it is huge. I ordered some more and if that one comes back as an alexandrite I will keep ordering them.
