Crystal Tree vs Crystal Cluster
Partager
Ask what the surface is for.
A coffee table that needs a focal point can take a tree. A nightstand that already holds a lamp and a glass cannot. A cluster sits lower and asks less of the air above it.

Tree
Height and color from five feet away. Citrine and mixed-chip trees work in living rooms and on wide shelves with clearance above the canopy.
Wire trunks collect dust. Hold the base when you brush.
Gifts well: it looks finished in a photo. See the gifts post.
Skip narrow consoles, desks with swinging arms, and any table a cat uses as a path.
Cluster
Low mass. Points catch side light. Amethyst on a nightstand or entry dish is the usual American use.
Needs a dish if the table is good wood. Points scratch.
Less of a gift silhouette unless the cluster is large enough to photograph as a landscape.
Skip the walking edge of a bench and any shelf at sleeve height without a tray.
Same room
Living room: tree on the table or cluster on the shelf—not both competing at the same height.
Bedroom: cluster. Save the tree for the room you walk through.
Entry: cluster or raw stone. Trees get knocked.
Care
Brush both. Do not soak the tree. Full notes in the care post.
If you only buy one
Sofa-first and you like a gift look: tree. Sleep-first or a small table: cluster.
