Its presence in history, as both a treasured gem and a symbol of strength, continues to enchant gemstone aficionados and jewellery connoisseurs around the world.

Cubic Zirconia, often abbreviated as CZ, is a synthetic gemstone that has gained popularity as a brilliant and affordable alternative to natural diamonds. Its name stems from its crystal structure, which is cubic in nature, closely resembling the crystal lattice of diamond.

Cubic Zirconia is created in laboratories through a meticulous process that involves melting zirconium oxide and yttrium oxide at extremely high temperatures and then cooling it to form colourless, flawless crystals. This synthetic gemstone can also be crafted in various colours by adding trace elements to the crystal mixture.

While it is not found in nature, the appeal of Cubic Zirconia lies in its diamond-like sparkle and affordability, making it a popular choice for jewellery, particularly as a diamond simulant. Its introduction in the 1970s revolutionized the gemstone market, offering an accessible option for those seeking brilliant, sparkly jewellery without the cost associated with natural diamonds.

Fluorite, a mesmerizing gemstone known for its wide range of brilliant colours, owes its name to the Latin word "fluere," meaning "to flow." This moniker is a nod to its historical use as a flux in metallurgy, aiding in the flow of molten metals during smelting processes.

Chemically, fluorite is a calcium fluoride mineral that forms in a cubic crystal system. It is renowned for its stunning variety of colours, which can include shades of purple, green, blue, yellow, and more. These colours result from different trace elements present during its formation.

Fluorite typically occurs in hydrothermal veins and is often associated with minerals like quartz and calcite. Its striking fluorescence under ultraviolet light is a distinctive feature, earning it a place in fluorescent mineral collections.

One interesting property of fluorite is its use in optical devices due to its low dispersion, which minimizes colour aberration. It is also used as a source of fluorine in various industrial applications. Whether appreciated for its aesthetic beauty or utilitarian purposes, fluorite continues to captivate gemstone enthusiasts and mineral collectors worldwide.

Jadeite, a captivating and highly-prized gemstone, draws its name from the Spanish phrase "piedra de ijada," meaning "stone for the pain in the side." This name hails from the belief that jadeite could cure ailments when held against the side. Composed of sodium and aluminium silicate, jadeite is one of two distinct mineral species known as "jade," with the other being nephrite.

Geologically, jadeite forms in high-pressure, low-temperature environments, often within subduction zones where tectonic plates collide. Notable sources include Myanmar, Guatemala, and Japan, with Burmese jadeite being particularly renowned for its exquisite quality and vibrant green colour.
