How do rubies and sapphires

It’s not magic. It’s science.

Lab-grown rubies are created using the same elements as natural rubies:
• Aluminum oxide
• Chromium (for red color)

Grown under high heat & pressure, replicating the earth’s process.

The result:
Vivid, clean, ethical, stunning rubies.

Beauty with a clear conscience.
