Amazonite crushed powder FAQs

Current PEP Rocks grades: Medium: Light Turquoise; Fine: Pale Mint-Aqua

What color is crushed amazonite powder?

PEP Rocks amazonite offers a fresh blue-green palette, including Light Turquoise in medium grade and Pale Mint-Aqua in fine grade. Both offer attractive mineral accents for resin jewelry, inlay, and decorative art.

Is amazonite the same as turquoise?

Amazonite is a potassium feldspar; turquoise is a different mineral, a hydrated copper-aluminum phosphate. Similar blue-green colors do not make them interchangeable.

Amazonite can add a turquoise or mint-aqua mineral accent to resin art, depending on grade and concentration. Try a small cured sample with your chosen resin to evaluate the finished effect.

Amethyst crushed powder FAQs

Current PEP Rocks grades: Coarse: Lavender Purple; Medium: Dusty Lavender; Fine: Soft Lavender Mist; Super Fine: Delicate Lavender

Does crushed amethyst powder keep its purple color in resin?

PEP Rocks amethyst grades offer an elegant lavender palette: Lavender Purple (coarse), Dusty Lavender (medium), Soft Lavender Mist (fine), and Delicate Lavender (super fine). The finished resin color depends on loading and lighting.

Is amethyst powder dyed, or is the purple color natural?

Amethyst's violet color is naturally associated with iron-related color centers in quartz. Color and treatment history vary by source. Do not infer that a particular batch is untreated solely from its gemstone name; ask for supplier documentation if treatment status matters.

What's the difference between amethyst fine powder and super fine powder for body scrubs?

Fine and super fine refer to grinding grades. For cosmetic formulation development, suitability depends on verified particle size, material safety, abrasion, and finished-product testing; neither grade is automatically approved for body scrubs.

Black Obsidian crushed powder FAQs

Current PEP Rocks grades: Coarse: Charcoal Black; Medium: Smoky Grey; Fine: Smoky Grey

Is black obsidian powder the same as glass powder?

Obsidian is naturally formed volcanic glass, not manufactured glass. Once crushed, its appearance depends on particle size: PEP Rocks coarse material is charcoal black, while medium and fine powder are classified as medium grey.

Does crushed black obsidian powder look black or dark gray in resin?

PEP Rocks black obsidian offers Charcoal Black in coarse grade and sophisticated Smoky Grey tones in medium and fine grades. Appearance in finished resin depends on the resin and amount used.

Is black obsidian powder safe to handle?

Obsidian fractures into particles that can have sharp edges. Avoid inhaling dust and getting particles into eyes, use appropriate dust controls and eye protection, and wash after handling. Fine particles are not automatically harmless just because they are smaller.

Black Tourmaline crushed powder FAQs

Current PEP Rocks grades: Fine: Deep Charcoal Grey

PEP Rocks fine black tourmaline has an elegant Deep Charcoal Grey appearance with rich, dark mineral character. Finished colors in resin depend on the resin and amount used.

What's the difference between black tourmaline powder and black obsidian powder?

Black obsidian is volcanic glass, whereas black tourmaline is a crystalline boron-silicate mineral. Their texture, composition, and behavior during crushing differ. Both may appear grey when ground finely rather than matching the color of a polished black stone.

Does black tourmaline powder work in resin art?

Black tourmaline can be trialed as a decorative particulate filler in resin, but dispersion, appearance, and cure compatibility depend on the formulation. Begin with a small test and follow the resin manufacturer's handling instructions.

Calcite crushed powder FAQs

Current PEP Rocks grades: Coarse: Silvery White; Medium: Pale Grey-White

What color is calcite powder?
