The basics

So... what makes a statement piece?

Size, rarity, or both. It's the rock that becomes the centre of the room.

A geode is a hollow rock lined with crystals. A cathedral is a tall geode stood on end. A cluster is crystals grown from one base. A specimen is a mineral kept close to how it was found.

Treated stones say so. Citrine cathedrals marked Enhanced are heat-treated amethyst.

Choosing

How to pick yours

  1. Start with the spot

    Shelf, table or floor? Measure it first. Most listings give a size, and many give a weight.

  2. Think about light

    Quartz sparkles near a window. Keep amethyst out of strong direct sun so the purple stays rich.

  3. Set a budget

    Smaller U# clusters start under $100. Room-stopping cathedrals and spheres run into the thousands.

Using it

Living with a big rock

  1. Lift from the base

    Hold it from underneath, never by the points. Heavy pieces are a two-person job.

  2. Give it a solid home

    Use a sturdy, level surface. A display stand keeps spheres and odd shapes steady.

  3. Dust, don't wash

    A soft dry brush is enough. Some stones, like selenite and apophyllite, don't like water.

Good questions

Questions people ask us

Is the one I get the one in the photo?

Yes, if the title says U# or Unique. That's one specific piece, photographed and measured. Listings with a size range, like 3-5", are picked from a batch.

How big is it, really?

Check the title and details for size and weight, then measure your shelf. Photos can fool you.

Are these natural?

Most are natural stone. Some get a polished face or a cut base so they stand flat.

Why do some cost so much?

Size, clarity and rarity. A fist-sized quartz cluster is common. A 35 lb super-clear one is not.
