Lab-grown sapphires can be produced in various colors, such as blue, pink, yellow, green, purple and even colorless (white). These lab-grown gemstones have the same physical and chemical properties as natural sapphires, making them almost indistinguishable to the naked eye. However, gemologists can often identify them through specialized testing.

One of the main advantages of lab-grown sapphires is their affordability compared to natural sapphires, which can be quite expensive due to their rarity and the cost of mining. Additionally, lab-grown sapphires are considered more environmentally friendly since they do not require extensive mining and have a smaller carbon footprint.

Q: Can a jeweler tell if a stone is lab-created?


A: Yes, a jeweler can often determine if a stone is lab-created, though the ease of identification depends on their experience and the tools available. One way to distinguish lab-created gemstones is by examining inclusions. Lab-created stones may show characteristics like gas bubbles or specific growth lines that differ from natural gems.

Jewelers often use spectroscopy to analyze the light absorption and emission properties of a stone, revealing chemical compositions that can indicate whether a gem is natural or synthetic. Additionally, the refractive index, measured with a refractometer, can provide clues, as lab-created gems may exhibit slight variations.

Many lab-created gemstones come with certification from gemological laboratories, confirming their synthetic origin. A jeweler can easily verify this documentation.

While some lab-created stones closely resemble their natural counterparts, experienced jewelers with the right tools can usually differentiate between them, ensuring informed purchases for consumers.
