Locale: Indonesia

Set count: ten miscellaneous crystals

Set total weight: 16–18g

Largest crystal in each set measures A 2.0cm; B 1.9cm; C 1.6cm; D 1.9cm; E 1.8cm; F 1.8cm; G 1.8cm; H 1.8cm; I 2.2cm; J 1.9cm; K 2.1cm; L 1.8cm; M 1.9cm; N 1.8cm; O 2.2cm. The “surprise me!” option will be comparable to these sets.

 

Beta quartz (β-quartz), also sometimes called “high quartz,” is a paramorph: a pseudomorph of the same chemical composition but different crystal structure. Standard quartz (α-quartz) is transformed into β-quartz under high temperatures, which is why the crystals are most commonly found in volcanic rock environments. The β-quartz is stable above 573°C/1063°F and then reverts to α-quartz when it cools. The final product is considered a quartz paramorph after beta quartz. 

These six-sided bipyramidal crystals from Indonesia display the typical beta quartz crystal habit. The surface texture is rough on a lot of these and all sets include crystals that are not whole (it’s simply too common not to!). Many crystals have interesting indented rings on their surface, which may be from crystals that dissolved away; others have indented spots or irregular patterns caused by etching. Some beta quartz crystals have neat split growth, capped points, or additional faces (learn more about quartz growth forms).

These beta quartz crystals are in their natural state. Some collectors and dealers will clean them with acids to remove the brown coloration. Cleaned Beta quartz will be close to white but the material typically doesn’t gain much translucency or glitter and can look like a sugar cube. Personally I prefer the warm tones of the natural coloration. That part of why these are offered in sets and not individually, because it shows the range of palette, sizes, and surface variations. The base color is a warm tan, but colors can range from deep reds, browns, and black to light yellow-browns. Some crystals have a white coating on the faces with bare darker junctions creating an interesting visual effect like a model crystal.

This material is mostly near-opaque but can be translucent at time times. Curiously, of the two crystals I have accidentally broken, one was the same color throughout but the other (pictured) had a dark core with almost metallic luster.
