Gemstone Buying Guide

A Guide to Choosing Coloured Gemstone Jewellery

The Beauty of Coloured Gemstones

Coloured gemstones bring individuality, symbolism and vibrant character to fine jewellery. At ZEN Diamond, our gemstone collections bring together the natural beauty of sapphires, emeralds, rubies and other coloured gemstones with fine gold craftsmanship. Whether chosen for their colour, personal meaning or distinctive character, each gemstone adds its own expression to a jewellery piece.

Key Factors to Consider When Choosing a Gemstone

Colour

Colour is one of the most important characteristics of a coloured gemstone. The richness, intensity and saturation of the colour can have a significant influence on the gemstone’s beauty and value. When selecting a gemstone, consider the depth and appeal of its colour in the context of the finished jewellery design.

Clarity

Clarity in coloured gemstones is assessed differently from diamonds. Natural inclusions can be common and may be accepted depending on the type of gemstone. Rather than expecting every coloured gemstone to be completely free of inclusions, consider how its clarity characteristics affect its overall beauty and appearance.

Cut

The cut determines how a gemstone interacts with light and can influence both colour intensity and brilliance. A well-considered cut can enhance the gemstone’s natural character and help bring out its colour within the jewellery design.

Carat

Carat refers to the weight of a gemstone. Because different gemstones have different densities, two gemstones with the same carat weight may appear different in size. The visual presence of a gemstone should therefore be considered alongside its carat weight.

Treatments

Some coloured gemstones may undergo treatments to enhance or improve characteristics such as colour, clarity or durability. ZEN Diamond is committed to transparent disclosure of gemstone treatments where applicable, so customers can make informed purchasing decisions.

Birthstones

Birthstones offer a meaningful way to personalise a jewellery choice. The traditional monthly associations below can help you select a gemstone connected with a birth month or personal significance.

·       January: Garnet

·       February: Amethyst

·       March: Aquamarine

·       April: Diamond

·       May: Emerald

·       June: Pearl / Alexandrite

·       July: Ruby

·       August: Peridot

·       September: Sapphire

·       October: Opal / Tourmaline

·       November: Citrine / Topaz

·       December: Tanzanite / Blue Topaz

Choosing the Right Gemstone for You

·       Start with the colour that naturally appeals to you and complements your personal style.

·       Consider the gemstone’s clarity and natural characteristics as part of its individual identity.

·       Look at the cut and finished design together, as the setting can influence the way the gemstone is seen.

·       Consider carat weight together with the gemstone’s density and visual size.

·       Ask about applicable treatments and review any available product or gemstone documentation before purchase.

·       For a meaningful gift, consider selecting a gemstone associated with the recipient’s birth month.
