Whether you are a gemstone enthusiast, a jewelry buyer, or simply curious about the meanings behind these stones, this guide provides a comprehensive overview of the most widely recognized birthstones and their significance.
Introduction
Birthstones have long been regarded as symbols of identity, protection, and personal significance. The tradition of assigning gemstones to specific months of the year has its roots in ancient cultures and biblical lore.
