FAQ

Are Emeralds natural or lab created?

Most Emeralds are natural beryl. Due to Emerald’s internal inclusions, treatments such as oiling or resin filling are very common and expected.

How durable are Emerald beads?

Emerald ranks 7.5–8 on the Mohs scale, making it very durable and great for earrings and necklaces. Care is recommended for bracelets and rings.

What are notable characteristics about Emerald's appearance?

Emeralds naturally form with internal fractures and inclusions known as jardin. Also, Emerald displays a phenomenon called pleochroism, meaning its color can change depending on what angle you look at it from.

Can Emerald beads be faceted?

They can be faceted, but many emerald beads are cut smooth or lightly faceted to reduce stress on the stone and prevent chipping.

How do you take care of Emerald gemstones?

Avoid ultrasonic and steam cleaners. Use mild soap, water, and a soft cloth. Emerald treatments can be damaged by heat and chemicals.

Where is Emerald commonly found?

Common sources include Colombia, Zambia, Brazil, and Ethiopia, each producing different green tones and clarity characteristics.

Are all Dakota Stones gemstone beads genuine?

Yes, all of our gemstone beads are made from authentic, natural materials. Any treatments (such as stabilization or dyeing) are clearly noted.

Are gemstone beads durable for everyday jewelry?

Most stones are durable, but hardness varies. Softer stones (below 6 on the Mohs scale) are best for necklaces or earrings rather than rings or bracelets.

How are Dakota Stones ethically sourced?

We work directly with trusted suppliers around the world to ensure responsible mining, fair labor, and environmentally conscious sourcing.
