Geological Formation and Sources
Ruby
Ruby is a variety of the mineral corundum, which is composed of aluminum oxide (Al₂O₃) with trace amounts of chromium or vanadium, which give it its characteristic red color. The finest rubies are found in Myanmar (Burma), where they have been mined for centuries. Other notable sources include Thailand, Sri Lanka, and Madagascar. The most valuable rubies are those with a deep red color known as "pigeon blood," which is particularly rare and highly sought after.
Ruby is formed under high pressure and temperature conditions deep within the Earth’s crust. Over millions of years, geological processes cause the mineral to crystallize and develop its vibrant color. The hardness of Ruby on the Mohs scale is 9, making it one of the hardest and most durable gemstones, suitable for use in a wide range of jewelry.
Moonstone
Moonstone is a type of feldspar mineral that exhibits a unique optical phenomenon known as adularescence. This effect causes a shimmering light to appear to float across the surface of the stone, giving it a soft, ethereal glow. The best moonstones come from Sri Lanka, where they are known for their high quality and striking appearance. Other sources include India, Brazil, and the United States.
Moonstone forms in igneous rocks and is typically found in granitic or syenitic formations. It is relatively soft compared to Ruby, with a hardness of 6 to 6.5 on the Mohs scale. This makes it more delicate and requires careful handling to avoid scratches or damage.
Carnelian
Carnelian is a translucent to opaque variety of chalcedony, which is a form of quartz. It is known for its warm, reddish-brown color, which is caused by iron impurities in the stone. Carnelian has been used for thousands of years in jewelry and amulets, particularly in ancient Egypt and the Middle East.
The primary source of high-quality Carnelian is India, where it is mined in the state of Rajasthan. Other notable sources include Brazil, Uruguay, and the United States. Carnelian is relatively hard, with a hardness of 6.5 to 7 on the Mohs scale, making it durable and suitable for use in a variety of jewelry settings.
Pearl
Pearls are organic gemstones formed within the soft tissue of living mollusks, such as oysters and mussels. They are composed primarily of calcium carbonate in the form of the mineral aragonite, along with some conchiolin and water. Unlike other gemstones, pearls are not mined from the Earth but are cultivated in pearl farms or harvested from natural sources.
The finest pearls are produced in the waters of the South Pacific, particularly in countries like Australia, Tahiti, and Japan. Freshwater pearls are also commonly found in China and the United States. Pearls are relatively soft and delicate, with a hardness of 2.5 to 4.5 on the Mohs scale. This makes them vulnerable to damage from harsh chemicals, heat, and abrasion.

Care and Cleaning
Due to their varying hardness and sensitivity, the Cancer birthstones require careful handling and regular maintenance to preserve their beauty and durability.

Ultrasonic and steam cleaning are also safe options.
Moonstone
Moonstone is more delicate than Ruby, with a hardness of 6 to 6.5. It is sensitive to heat and chemicals, so it should not be exposed to high temperatures or abrasive substances. To clean Moonstone, use a soft cloth and mild soap. Avoid using ultrasonic or steam cleaners, as these can cause damage.

Pearl
Pearl is one of the most delicate gemstones, with a hardness of 2.5 to 4.5. It is highly sensitive to heat, chemicals, and abrasion. To clean Pearl, gently wipe it with a soft, dry cloth.
