Lab-Grown Sapphires Explained: What They Are and How They Compare to Natural Stones

Lab-grown sapphires are real sapphires in terms of their chemical and physical composition, but rather than forming naturally over millions of years, they are created in controlled laboratory conditions. For people searching “lab-grown sapphire vs natural sapphire” or “are lab sapphires real,” the key distinction is origin—not quality or appearance.

What is a lab-grown sapphire?

A lab-grown sapphire is made from the same mineral as natural sapphire (corundum). The result is a stone that is visually and chemically identical to a mined sapphire, but typically more affordable and more readily available in consistent colours and larger sizes.

Because they are grown in controlled conditions, lab sapphires often have:

  • Fewer visible inclusions
  • More uniform colour
  • Greater availability in larger carat sizes

Why natural sapphires vary so much in value

Natural sapphires are formed deep within the earth under intense pressure and heat, which makes high-quality stones relatively rare—especially in larger, vividly coloured examples.

Their value is heavily influenced by:

  • Colour intensity (deep, vivid blues are most prized)
  • Clarity (fewer inclusions increases value)
  • Origin (some regions are more highly valued than others)
  • Size (large high-quality stones are significantly rarer)

As carat size increases, high-quality natural sapphires become much harder to find, which is where pricing rises sharply.

Lab-grown vs natural sapphires

The key difference is not appearance, but rarity and market value.

  • Lab-grown sapphires: visually identical, more affordable, widely available in larger sizes
  • Natural sapphires: rare, value driven by scarcity, especially in fine quality stones
  • Both: share the same durability (sapphire is one of the hardest gemstones used in jewellery)

Are lab-grown sapphires worth it?

Lab-grown sapphires are a strong option for those who want the look and durability of sapphire without the high cost of rare natural stones.

We like to use pink and purple lab-grown sapphires in our designs because they offer beautiful, saturated colour and durability at a lower cost to the consumer than natural sapphires.

However, we wouldn't recommend purchasing lab-grown sapphire jewellery with the expectation it will increase in value. Natural sapphires remain preferred for collectors and those prioritising rarity and long-term value, particularly in fine, untreated stones.

Final Thoughts

The choice between lab-grown and natural sapphires comes down to what you value more: accessibility and consistency, or rarity and provenance. Both are real sapphires—the difference lies in how they were formed, and how that impacts price and scarcity.

For customers seeking sapphire jewellery for colour, durability, personal style, and enjoyment, lab-grown sapphires are an excellent choice.
