Moldavite

About

Moldavite is a natural glass formed by the intense heat of a meteorite impact around 15 million years ago in what is now the Czech Republic. It is a type of tektite, and its unique olive to dark green hue is one of its most distinguishing features. Moldavite has a distinctive, wrinkled surface and often displays inclusions of gas bubbles, a result of its rapid formation and cooling. Its extraterrestrial origin has made it a favourite among collectors.

Birthstones & Anniversaries

Moldavite is not a traditional birthstone, but it is often linked to the zodiac sign Scorpio due to its transformative energy.

Facts

Meteoric origin: Moldavite was formed when a meteorite struck the Earth in the region now known as the Czech Republic around 15 million years ago.

Unique texture: Moldavite’s rough, textured surface is a result of its rapid cooling after the meteorite impact.

Distinctive colour: Moldavite’s olive-green to dark green hue is one of its most recognisable features.

Rare gem: Authentic Moldavite is becoming increasingly rare, as mining is limited to a small area in the Czech Republic.

Treatments

Moldavite is rarely treated, as its natural texture and colour are highly valued. Some lower-quality moldavite may be polished or cut to create smooth surfaces for jewellery, but the most prized specimens remain in their natural, unaltered state.

Synthetics

Due to its popularity and rarity, Moldavite is frequently imitated. ‘Synthetic’ moldavite is typically glass made to mimic the olive-green colour and surface texture of natural stones. These stones can often be identified through careful examination of inclusions, weight, and overall structure.

Imitations

Green glass is the most common material used to imitate Moldavite. These imitations often lack the natural bubbles, surface texture, and weight of genuine Moldavite, but they can be difficult to distinguish without expert testing.
