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: Is a green sapphire the same as an emerald?


A: No, green sapphires and emeralds are distinct gemstones with unique characteristics.

Composition: Green sapphires are a variety of corundum, composed of aluminum oxide, with their green hue resulting from trace elements like iron. Emeralds, on the other hand, belong to the beryl family and owe their vibrant green color to chromium or vanadium.

Hardness: Green sapphires are exceptionally durable, scoring 9 on the Mohs scale, while emeralds are softer, scoring 7.5 to 8, making them more prone to scratches or chips.

Appearance: Green sapphires often display a range of green tones with fewer inclusions, giving them higher clarity. Emeralds, prized for their intense green hue, typically have visible inclusions, known as "jardin," which add to their character.

Value: Green sapphires are more affordable and less rare, while high-quality emeralds with vivid color and minimal inclusions are highly valuable.

Both gemstones are stunning choices, but their differences make each uniquely suited to different tastes and needs.
