Beryl Gemstone Beads

Frequently asked questions

• What are the varieties of beryl?

  The named gem varieties of beryl are morganite (pink to peach, colored by manganese), aquamarine (pale blue to blue-green, colored by iron), emerald (saturated green, colored by chromium or vanadium), heliodor and golden beryl (yellow to yellow-green, colored by iron), goshenite (colorless), and red beryl or bixbite (a rare collector stone from Utah, essentially absent from the bead trade). All share the same beryllium aluminum silicate chemistry, the same hexagonal crystal habit, and the same Mohs 7.5–8 hardness — the differences are trace-element chromophores. Dakota's active beryl inventory centers on morganite, aquamarine, emerald, and heliodor / golden beryl, predominantly Brazilian-sourced.
• Is morganite the same as pink beryl?

  Yes. Morganite is the gem-trade name for pink-to-peach beryl, colored by manganese substituting into the beryl crystal lattice. The name was introduced in 1911 by Tiffany & Co. gemologist George Frederick Kunz, who named the variety after financier and gem collector J.P. Morgan. The material is mineralogically pink beryl; "morganite" is the trade name designers and the wider gem market use.
• Is aquamarine heated?

  Most commercial aquamarine is heat-treated. The natural rough often shows a blue-green or yellow-green tone; heating drives the iron chemistry toward pure blue and produces the saturated sky-blue and deep-blue color the market prefers. The heat treatment is permanent, stable, and undetectable in the polished bead — it is the trade default rather than an exception. Untreated aquamarine exists as a smaller premium segment and is usually labeled as such. Treatment status should be disclosed; ask before buying if it isn't specified.
• How durable is beryl for daily wear?

  Mohs 7.5–8 across all varieties — durable enough for any jewelry application including rings, bracelets, and necklaces. The one care note specific to the family: emerald is almost always oil-treated to fill surface-reaching fractures, so avoid ultrasonic and steam cleaning on emerald strands. Morganite, aquamarine, and heliodor / golden beryl tolerate standard cleaning when untreated; confirm treatment status before assuming ultrasonic safety.
• Where does Dakota's beryl come from?

  The active beryl inventory with origin tagging is overwhelmingly Brazilian — the Minas Gerais pegmatites in southeastern Brazil are the dominant world source for morganite, aquamarine, and heliodor / golden beryl. Emerald strands may source from Brazil, Colombia, or Zambia depending on the buy. Specific origin should be disclosed; ask before buying if it isn't specified.
