King of Precious Stones

Ruby is the red variety of the mineral corundum, one of the hardest minerals on Earth. Corundum is the mineral form of alumina, which crystallizes in the hexagonal system.


A Royal Affair

Emerald is the bluish-green to green variety of beryl, a mineral species that includes aquamarine.


Stone of Royalty

Sapphires are one of the hardest stones on the planet; only diamonds surpass them in hardness! 🔨 Sapphire is also a variety of the mineral Corundum and represents all the colors except red Corundum (which is Ruby).


The Ancient Blue Gem

Turquoise is the only gemstone that has a color named after it. 💙💎 Turquoise can be identified by its distinctive sky blue, blue-green, or apple-green color and waxy to matt luster.


The Warm, Reddish Gem

Ancient peoples all over the world favored the warm, reddish gem known as Carnelian. This material was easy to cut into jewelry stones as well as carved into seals and talismans. Carnelian symbolism and lore came to encompass health, luck, and royalty.


The Silica Crystal Gem

Quartz is the second most common mineral in Earth's crust. Many varieties are precious gemstones, including amethyst, citrine, smoky quartz, brandy quartz and rose quartz.


Gems of Every Hue

Garnets are a set of closely related minerals forming a group, with gemstones in almost every color. Red garnets have a long history, but modern gem buyers can pick from a rich palette of garnet colors: greens, oranges, pinkish oranges, deeply saturated purplish reds, and even some blues


Lustrous & Brilliant Gem

Topaz is a pleochroic gem, meaning that the gem can show different colors in different crystal directions. Topaz has so many more colors to offer gem lovers, including pinks and purples that rival the finest fancy sapphires.


Deep Yellowish-Green Gem

Peridot is an ancient Gem of the mineral Olivine. The peridot gemstone is known for its greenish-yellow coloring and ranges from a solid green to green with hints of brown or yellow.


The Black Prince's Ruby

Although frequently confused with ruby, spinel stands on its own merits. Available in a striking array of colors, its long history includes many famous large spinels still in existence. Increasing demand for ruby alternatives rekindled appreciation for spinel’s rich red color and history.


The Imperial Gem

Jadeite is a member of a group of related minerals called pyroxenes. Jadeite was discovered in Burma sometime in the 18th century and it quickly became prized by Chinese emperors.
