Garnet is the birthstone for January
Anyone celebrating a birthday at the start of each year benefits from Garnet for their birthstone.
Associated with a dark red colour, gem Garnets come in many different hues and in a variety of colours.
Rich in colour, transparent and inexpensive, garnet makes an affordable choice when it comes to jewellery for a January birthday or anniversary.
Most sources of Garnet originate from a sedimentary rock with high aluminium content—such as shale. To explain, the rock becomes metamorphosed under great heat and pressure, Garnet forms.
Shapes, colours and sizes
Garnet comes in many different colours. For example, green, red, yellow and orange. In addition, these birthstone gemstones occur in many shapes and sizes.
Our example below comes from our limited-edition gemstones available from our Ryde showroom or from our online shop.

Alternative to Ruby
Garnet makes an excellent alternative to Ruby. In particular, when you consider the cost difference. Similarly, most jewellers work with gem-quality Garnet within their gemstone birthstone selections.
Is it hardwearing?
Garnet is fairly hardwearing, measuring 6.5 – 7.5 on Mohs Scale. Therefore, it makes a popular choice for birthstone rings in addition to many other types of jewellery. In fact, jewellers favour this gemstone which debuts in the month of January. Furthermore, it makes a perfect introduction for the Valentine’s Day season.
Many sources suggest that Garnet is sensitive to heat. Therefore, we recommend care during jewellery making where high temperatures are used.
Forms of Garnet
This gemstone varies considerably in its chemical composition and crystal structure. In fact, many varieties exist as outlined below.
Hydrogrossular: Bluish-green Garnet with far less transparency.
Pyrope Spessartine: Chrome pyrope Garnet makes the perfect alternative to Ruby, prized for its deep red tones. Spessartine: Orange variety, most prized in the Mandarin orange colour.
Uvarovite: Rare, dark, rich green usually in small sizes and compared by many to Emerald.
Almandine Garnet: Most common gemstone in the Garnet family—available in many colours. The blend of almandine-pyrope forms the deep red variety most people associate with this popular gemstone.
Andradite: One of the rarest varieties of Garnet. Some suggest this type of gemstone has even more fire than diamond. Green demantoid is highly valued amongst collectors.
Grossular: Available in many colours. This type suits jewellery with bright and vivid colours with the exception of blue.
The Spessartite-Grossular-Pyrope color-change Garnet can show a change of colour from light blue-green to purple depending on the fluorescent light source. In addition, daylight results in the colour showing as a light red to purple-red.
Gemmologists and gemstone dealers further categorise many varieties into sub-divisions depending on their colour. For example, demantoid is a vivid green variety of andradite that’s highly coveted by collectors.
Tsavorite and Hessonite are types of grossular. Tsavorites are green, but Hessonite varies between orange and orangish-red to brown-red. Rhodolite is a purplish red version of the gemstone.
January Birthstone Engagement Ring
Garnet can make an ideal gemstone for an engagement ring. In particular, when favoured to Ruby as a less-expensive alternative. Furthermore, it contrasts very well when used as a centre-stone with April’s birthstone – diamond.
Most of our ring designs can be set with this intense birthstone instead of a diamond. In addition, this gemstone adds full contrast when set alongside brilliant white diamonds. As displayed here in our Sienna engagement ring.
