Foundational knowledge for the curious collector — how gemstones form, how they endure, and what to look for.
What is a gemstone?
A gemstone is a mineral, rock, or organic material chosen for beauty, rarity, and durability. Once cut and polished, it becomes the heart of fine jewelry.
Hardness & durability
Measured on the Mohs scale, hardness determines how a stone resists scratching. Sapphire and ruby (9) wear daily; opal and pearl require gentler care.
Color, clarity & cut
Color is the leading value driver in colored gemstones. Clarity expectations vary by species, while a well-executed cut brings the stone to life.
Natural vs. lab-grown
Lab-grown gemstones are chemically identical to mined stones. Both are real — the choice comes down to origin, rarity, and personal preference.
Tutorial
How to choose your gemstone
A simple, considered path — from feeling to finished piece.
Start with meaning
A birth month, an anniversary, a color that speaks to the wearer. Meaning makes the choice personal.
Match to lifestyle
Consider how the piece will be worn. Daily rings call for harder stones; earrings and pendants invite softer beauties.
Choose a setting
Bezel, prong, halo — the setting protects the stone and shapes its character. Metal color shifts the gem's tone.
Customize with an expert
Work one-on-one with a Ritani gemologist to source the stone and design a piece that's truly yours.

Common Questions
Frequently Asked Questions
What is a gemstone?
A gemstone is a mineral or rock that is cut and polished for use in jewelry or other decorative items. There are hundreds of types of gemstones, but the most common are diamonds, rubies, emeralds, sapphires, and pearls. Gemstones are formed deep within the Earth's crust under extreme heat and pressure. They are found in a variety of locations around the world, including mines, riverbeds, and volcanic areas.
What are the gemstones for each month?
Each month is associated with a specific birthstone gemstone. The birthstones are as follows: January Birthstone - Garnet, February Birthstone - Amethyst, March Birthstone - Aquamarine, April Birthstone - Diamond, May Birthstone - Emerald, June Birthstone - Pearl or Alexandrite, July Birthstone - Ruby, August Birthstone - Peridot, September Birthstone - Sapphire, October Birthstone - Opal or Tourmaline, November Birthstone - Citrine or Topaz, and December Birthstone - Turquoise, Tanzanite or Zircon. Discover our birthstone jewelry collection to shop all.
What is the rarest gemstone?
The rarest gemstone is painite, which was discovered in Myanmar in the 1950s by British mineralogist Arthur C. D. Pain. Once considered the rarest mineral on Earth, only a handful of painite crystals are known to exist. However, more recent discoveries have led to increased availability and reduced rarity. Painite is a reddish-brown or orange color and is highly sought after by collectors.
