What exactly is the difference between natural and lab-created gemstones? Let’s find out!

What Are Natural Gemstones?

Natural gemstones are minerals that have been cut and polished to be used in jewelry or other decorative objects. These stones are mined, meaning they originate from beneath the surface of the earth. Some of the most popular natural gemstones include diamonds, emeralds, pearls, and sapphires, among many others.

Natural stones are formed in multiple ways, including within the earth’s mantle, along a tectonic plate subduction zone, at asteroid impact sites, and even up in space. After the stones are found in locations around the world, they are then cut and polished by skilled artisans and used by jewelers to make timeless pieces, like rings, earrings, and pendants.

Although more expensive, purchasing a natural gemstone is a great investment since they appreciate in value over time. If you’re interested in purchasing a natural gemstone, it’s best to do as much research as possible. Not all natural stones are created equally, and some can be more valuable than others. Working with a reputable jewelry store can ensure you are getting the best quality gemstones for your money.

天然宝石与实验室培育宝石的具体区别是什么？让我们一探究竟！

什么是天然宝石？

天然宝石是经过切割和抛光、用于珠宝或其他装饰物品的矿物。这些宝石是开采而来的，也就是说它们源自地表之下。最受欢迎的天然宝石包括钻石、祖母绿、珍珠和蓝宝石等，种类繁多。

What Are Lab-Created Gemstones?

Lab-created stones are made in a lab with a similar process as the one that occurs beneath the earth for natural stones. The only difference is that these stones cost much less to make and take less time. Lab-created gemstones may also be referred to as “synthetic,” “artificial,” “man-made,” or “lab-grown”; however, these stones are just as genuine in their characteristics as mined ones.

During the creation process, mineral crystals that make up natural gemstones are synthesized, resulting in a stone that can have the same physical, chemical, and optical properties as its natural counterpart. This can happen in one of two ways:

• High Pressure-High Temperature (HPHT): A gemstone seed is placed in carbon and then exposed to extreme pressure and high temperatures that imitate what’s found below the earth’s surface. Once the carbon melts and cools, a crystallized stone is left behind.

• Chemical Vapor Deposition (CVD): A slice of gemstone seed is heated to extreme temperatures in a chamber with gas, such as methane. Then, tiny layers of crystal slowly “grow” onto the seed, eventually forming a full stone.

Are lab-created gemstones real? Absolutely! Lab-created stones have the same properties as natural gemstones and only differ in how they are made. Many people shopping for engagement rings may opt for a man-made gemstone, like a lab-created diamond, as a more affordable option, since these stones are not as expensive as mined ones.

实验室培育宝石是什么？

实验室培育宝石是在实验室中，通过模拟天然宝石在地底形成的类似工艺制成的。唯一的区别是，这类宝石的制作成本更低、耗时更短。实验室培育宝石也可被称为 “合成宝石”“人造宝石”“人工宝石” 或 “实验室生长宝石”；不过这些宝石在特性上与开采的天然宝石完全一致。

在培育过程中，构成天然宝石的矿物晶体会被合成，最终形成的宝石拥有与天然对应宝石相同的物理、化学和光学特性。这一过程主要通过两种方式实现：

高温高压法（HPHT）：将宝石种晶放入碳质材料中，然后暴露在模拟地底环境的极端高压和高温条件下。当碳质材料熔化并冷却后，就会留下结晶化的宝石。

化学气相沉积法（CVD）：将一片宝石种晶置于充满甲烷等气体的反应室中，加热至极高温度。随后，微小的晶体层会缓慢 “生长” 在种晶上，最终形成完整的宝石。

What Are the Differences Between Natural and Lab-Created Gems?

The main difference between lab-created gemstones and natural gemstones is how they are made. Lab-created gemstones are made in a controlled environment using advanced technology. This allows for more consistent quality and color than what can be found in nature. Natural gemstones are created by nature over millions of years, subject to imperfections caused by the earth’s formation processes.

Differentiating natural and lab-created gemstones can be tricky, but some key characteristics can help you tell them apart. Here is a closer look at the differences between natural and lab-created gemstones:

• Appearance: Lab-created gemstones are often made of cheaper materials and have a more uniform appearance. Natural gemstones, on the other hand, are formed over time by nature and have unique variations in color, clarity, and cut. Keep in mind, however, that both types of stones are graded using the four C’s.

• Cost: Because natural gemstones are rarer and must be mined from the earth, they are more expensive. In contrast, lab-created gemstones typically cost less than natural gemstones because they are mass-produced.

• Durability: Lab-created gemstones are often made of stronger materials and have a higher resistance to wear and tear. Natural gemstones can be more fragile and may be susceptible to damage, depending on the gem.

Fortunately, unless you view a stone at extremely high magnification with a special instrument, it’s very difficult to see any physical differences between a lab-created stone and a natural one. The biggest differences are seen in the creation process and value of the two stones. This is why many may opt for a lab-created gem as a more affordable option since its appearance is very similar to a natural one.

Are Imitation or Simulated Gemstones the Same as Lab-Created Gemstones?

Many people believe that imitation, or simulated, gemstones are the same as lab-created ones. However, this is not true; there are actually some key differences between these two types of stones.

Simulated gemstones are usually made from cheaper materials, such as glass, plastic, or another stone than what it claims to be. While they are intended to look like natural gems, their composition is not the same and does not follow the same creation process as what’s found under the surface of the earth.

Imitation or simulated gemstones are often used in costume jewelry or for other decorative purposes, and they are also not as valuable as lab-created gems. This is because they are not as rare, nor are they as durable. Lab-created gemstones are real stones, will last longer, and will retain their value better over time.

天然宝石与实验室培育宝石的区别是什么？

区分天然宝石和实验室培育宝石并非易事，但通过一些关键特征可以分辨。下面我们来详细了解两者的区别：

外观：实验室培育宝石通常由成本更低的材料制成，外观更统一。而天然宝石是大自然长期形成的，在颜色、净度和切工上都有独特的差异。不过要注意，两类宝石都依据 4C 标准进行分级。

价格：天然宝石更为稀有，且需要从地下开采，因此价格更高。相比之下，实验室培育宝石因可批量生产，价格通常低于天然宝石。

耐用性：实验室培育宝石多由更坚固的材料制成，更耐磨。而天然宝石相对更脆弱，部分品类还容易受损，具体取决于宝石种类。

幸运的是，除非借助专业仪器在极高倍率下观察，否则很难看出实验室培育宝石和天然宝石在物理上的差异。两者最大的区别在于形成过程和价值。这也是许多人会选择实验室培育宝石作为更经济实惠的选择的原因，因为它们的外观与天然宝石极为相似。
