Semi-Precious Gemstones

| Cian Tilley


Topaz is one of the world's most popular coloured gemstones. It's a hard gemstone with excellent clarity offering extremely good value for money. Ebony Jewellery designs use blue topaz of which there are three different types: Sky Topaz is a pale blue stone, Swiss Topaz is a mid bright blue and London Topaz is a darker blue. The bright Swiss Blue Topaz, reminiscent of a blue ocean, is the type used in our designs.


Peridot belongs to the olivine group of stones and, unlike most other gemstones, are an “idiochromatic” gem meaning its colour comes from the chemical composition of the mineral itself and not from contact with external materials. As a result, peridots are found in shades of one colour only: green. They refract light wonderfully and have a lively, contemporary, almost lime-green colour, which tones beautifully with yellow gold. They are becoming ever more popular and Ebony Jewellery uses them in a variety of designs.


Garnets are widely known as a deep red gem. The name “garnet” derives from “gernet”, which is old English for “dark red” and “granum”, the Latin for “grain or seed”. This may be a reference to the pomegranate whose vivid red seeds can look similar to some garnet crystals. Garnet is also found in other colours.


Rhodalites belong to the garnet group and are also known as Rhodalite Garnet. They tend to be lighter in colour than a garnet—a more pink-red or rose shade—and are often regarded as a higher-quality gemstone as it has more sparkle. 


Like opals, moonstones diffract light and this visual effect gave rise to the stone’s name. Moonstone has been used in jewellery and rings since ancient times and is associated with the power and mystery of the moon. We source the top grade moonstone colour known as fine blue.


Pearls are created within molluscs and are renowned for their lustre and the way light reacts with their surface. We use freshwater pearls from freshwater mussels.

Care must be taken when cleaning pearls and they should never be placed in silver dip. 

Hematite (Haematite)

A mineral form of iron oxide, this stone is red when cut or powdered, and its name comes from the Greek for “blood”. Unlike other precious and semi-precious stones, hematite is opaque and does not diffract light. Its surface has a magnificent metallic shine and it can look similar to silver when polished. 


This stone is scientifically known as banded chalcedony, which is a form of silica containing quartz. Onyx occurs in many colours, notably black, white and red, but when red it is known as sardonyx. It becomes wonderfully shiny when polished.


Amethyst is the purple variety of crystalline quartz, with colours ranging from pale lilac through to deep reddish purple. Unlike many gems, amethyst is readily available in larger sizes and, due to this, even larger stones are comparatively affordable. These vibrant stones have been used in jewellery throughout history.


Citrine varies in colour from yellow and gold through to orange-brown shades. They are the yellow variety of crystalline quartz and are the second most popular quartz after amethyst. Like amethyst, citrine is an affordable gemstone and is also available in larger sizes. This gemstone looks striking set in both silver and gold.


Tourmaline appear in more colours than any other gemstone. They can exhibit a full spectrum of colours from colourless to black, and every tone from pastel shades to dark hues. Often more than one colour is visible in tourmaline.

Cubic Zirconia

Cubic Zirconia is a bright stone often set in silver as a very affordable alternative to diamond. This stone is also known by its initials CZ and is the only stone we use that has been produced synthetically rather than by nature. We use European cubic zirconia, which are brighter and of a higher quality than normal commercial CZ stones.
