January birthstone garnet 1月の誕生石ガーネット


January's birth stone is garnet. The traditional colour of garnet is deep red. However, like sapphire, it is a very versatile, colourful gemstone. It comes with any thinkable colours.

Many gemstones are heat-treated to enhance or change colours before being used in jewellery. But, garnet cannot be cooked. You cannot do anything to garnet. In other words, all garnet colours are natural.

Pyrope is the most well-known colour of garnet, often called Bohemian garnet, as everyone knows. iKuria's Hannah II stacking ring features the deep, rich red stone. It is also Marsala, the Pantone colour of 2015.

Slightly pinkish garnets are called rhodolite. Here are our transmuting gold earrings from the Alchemist's notebook collection.

Very cool green garnet is called tsavorite, used as the centre stone for another Hannah II stacking ring. Tsavorite is a variety of the grossular garnet, which includes cinnamon colour stones too.

Garnet comes in so many colours we have not been able to use them all. Below are other colours of garnet and how they are called.

Spessarine-Also called mandarin garnet is orange to red-brown.

Almandite - red with violet tint. 

Demantoid - includes colourless to bright green garnets. It is very rare and normally smaller than 1 carat.

September birth stone: sapphire 9月の誕生石:サファイア


Sapphire is the birthstone of September. It is my favourite gemstone (along with garnet).

Why? Because it is more versatile than one might think. Although blue is generally known as the colour of sapphire, it comes in any thinkable colours and shades. And it is a strong stone. And because it is my favourite stone, I use sapphire a lot for iKuria jewellery.

The sapphire is a gemstone variety of corundum species. Corundum includes sapphire and ruby. Yes, sapphire and ruby are actually the same stone. Mainly chromium impurities, or colouring agents, gives a red tint to a stone, which becomes ruby.

Other impurities yield other colours -- purple, yellow... you name it. Generally speaking, these corundum stones with other colours are all traded as sapphires. 

The corundum with pink-orange to orange-pink tones is specifically called padparadscha, which means a lotus flower colour in Sanskrit. Natural padparadscha sapphire is one of the rarest gemstones in the world.

Sapphire and ruby are the second hardest gemstone after diamond. They are durable. That's why iKuria usually recommends sapphire, ruby and diamond for engagement rings. 

*This is a broad-brush of sapphire. Please take a gemology course to learn more about the stone.

We use pink and blue sapphires for our Hannah collection.   ピンクとブルーサファイアのネックレス
