Quality Crystals & Minerals for Sale

At A Grain of Sand, quality means real crystals, honest minerals, and respect for their origins. Our store is stocked with selections like yellow aragonite specimens, permineralized petrified wood, and raw rhodonite pieces. Each item shows clear features — color, texture, structure — so you know what you're getting. When you buy a crystal bowl, slab, sphere, tower, skull, or freeform crystal piece, you’re holding something shaped by nature over time. You’ll also find quartz crystals made in Brazil. Look for clear quartz, amethyst, ametrine, citrine, and garden quartz (lodolite), each selected for quality and form.

Frequently Asked Questions

Are all your crystals and minerals authentic?

Yes. Every single piece you find on our website online is genuine. We source minerals with definite chemical composition — quartz, aragonite, petrified wood, tektite — not resins or imitation stones. You’ll get rocks or crystals that formed naturally, whether a raw cluster or polished freeform crystal. If a listing is vintage or includes trade beads or rare beads, it’s clearly marked.

What types of crystals and minerals do you sell?

We offer a wide range: raw clusters, freeforms, carved skulls, like our crystal skull for sale items, spheres, towers, slabs, geodes, petrified wood, and more. There are gemstone specimens like quartz, tektite, aragonite, rhodonite, and materials with unique texture or color. We also carry crystal bowls, palm stones, points, and fossils. The variety covers display pieces, small specimens, and gift-friendly items.

Are your minerals and crystals ethically sourced?

We aim to make sure the sourcing matches our quality. Most of our crystals come from known suppliers who follow fair trade and environmental practices. Because minerals, crystals, and such are often extracted from fragile landscapes, we choose those that minimize harm. If a particular specimen has an uncertain origin, we’ll note it or allow questions upon request.
