Enter Your Birth Date

We'll map your dominant Sun sign to its primary planetary stone, then walk through the full set: Sun, Moon, Mercury, Venus, Mars, Jupiter, Saturn, Uranus, Neptune, Pluto. Plus the 12 house stones.

The system

The Crystal Astrologer System

Marina Costelloe's Crystal Astrologer Course pairs every classical planet with a primary, secondary, and tertiary stone, giving you options for different intensities of work. The Sun stone is your identity stone, the Moon stone is your emotional support, and each subsequent planet expresses a different archetype.

The houses

12 Houses, 12 Life Areas

Beyond planets, the twelve astrological houses each map to a life domain, self (1st), money (2nd), communication (3rd), home (4th), creativity (5th), work (6th), partnerships (7th), transformation (8th), philosophy (9th), career (10th), community (11th), and inner work (12th). Each has its own primary stone.

About this tool

This tool draws on crystal astrology tradition. These are spiritual and reflective traditions, not medical or psychological treatments. Many people find these practices supportive for self-reflection and emotional well-being, but they should not be used as a substitute for professional care.

The planetary and house crystal correspondences are drawn from Marina Costelloe's Crystal Astrologer system. For a full natal chart with houses computed from precise birth time and location, use our Birth Chart Calculator.

For entertainment and self-reflection. Not a substitute for professional medical, legal, financial, or psychological advice.

Results are personal and vary from one person to the next. What many people find supportive may not work the same way for you, and nothing here is a promise of any specific result.

If you are experiencing significant emotional or physical distress, please consult a qualified professional.
