Ask whether it looks crisp or creamy
A crisper, glassier finish points people toward citrine more often. A creamier or softer look often points toward calcite.
These yellow stones can overlap in warm color, but they usually start separating once you compare how glassy, clear, or soft they look.

When this helps
Helpful when a yellow listing feels too soft for citrine or too glossy for calcite.
App Store note
On iPhone, the app listing appears as Rock Identifier: Gem & Crystal.
Quick answer
Citrine usually looks more quartz-like and glassy, while yellow calcite often appears softer, milkier, or more waxy. If the yellow feels creamy rather than crisp, yellow calcite becomes more likely.
Keep these in mind
Citrine is a quartz and often reads cleaner or glassier.
Yellow calcite often looks softer or cloudier.
Use finish and clarity, not just warm color, to compare them.
How to compare them
Many beginner mixups happen because warm yellow stones are sold into the same search intent, even when they do not behave the same visually.
A crisper, glassier finish points people toward citrine more often. A creamier or softer look often points toward calcite.
Seller lighting can make a pale yellow stone look much richer and more citrine-like than it does in neutral light.
The difference gets easier when you hold both possibilities in mind instead of trying to prove one name from one image.
Why use the app
Use the app to get to a likely match faster, then compare the result against the finish and clarity cues that separate quartz from calcite.
Snap one clear photo instead of guessing from memory.
Review likely matches when two stones look close at first glance.
Save stones you want to revisit, compare, or label later.

FAQ
It can be confused with citrine in beginner-facing shops and photo-only listings because both stones can appear warm yellow.
The overall finish usually helps first. Citrine often reads glassier, while yellow calcite more often looks softer or creamier.
Yes. Warm photography can push many yellow stones toward the same visual lane, which makes comparison more important.
