Petra swiss blue topaz

Blue Topaz

Since 2009 natural topaz crystals treatment is one of our top priority directions. This includes our technology of irradiation topaz coloring allowing to get Swiss Blue crystals from colorless topaz. By using the same technology on a natural amethyst we managed to intensify its color from light tinted crystal to the medium intensity colors.

Set your imagination free. Use it to the full and create masterpieces!
