Purchasing a Tourmaline is not your everyday decision, that’s why the coloured gemstone experts at Diamond Boutique have put together a guide to help you better understand the birthstone of October. Read on for more…
“Colour is what gives jewels their worth”
The quote above by Christian Dior is the best way to define the most important quality factor of a Tourmaline, the colour. Due to its chemical composition, tourmaline has a wide range of exciting colours to choose from.
When it comes to engagement rings, we recommend having either pink tourmaline otherwise known as rubellite tourmaline or the green kind also known as chrome tourmaline. Look for a tourmaline with consistent colour & minimal secondary undertones.
“A lack of clarity could put the brakes on any journey to success”
The above quote by Steve Maraboli applies to coloured gemstones too. Clarity is another important quality factor when selecting a coloured gemstone. Tourmaline grows in a liquid rich environment; therefore it is common for liquid inclusions to occur.
Make sure your tourmaline has eye clean clarity; this is when there are no inclusions visible to the naked eye. Liquid inclusions are usually less visible, so remember to use a loop to check your gemstones thoroughly for any presence before purchasing.
“A rough diamond must be cut and polished, or the lustre of it will never appear”
This quote by Daniel Defoe is also true for coloured gemstones; the cut of any gemstone defines its quality. Rough tourmaline is usually available in elongated forms; therefore are cut into long rectangular shapes, usually dependent on the colour.
Always remember that the cut of a tourmaline will depend on its crystal directions. We usually recommend oval and round cuts for engagement rings, because these shapes best display the gorgeous hues of tourmaline.
"The only carrots that interest me are the number of carats in a diamond"
One of our favourite quotes by Mae West, it is impossible to select any gemstone, be it coloured or a diamond, without mentioning the carats. Top quality tourmalines in larger carat sizes are rare and therefore fetch high per-carat price.
The ideal carat weight for a tourmaline used in an engagement ring is between 2 to 3 carats. Rubellite and chrome tourmalines of this size would be an affordable replace for pink sapphires and emeralds.
