9 Things To Know About November Birthstones
November has begun, bringing with it the perfect balance of autumn and winter. The rich hues of the leaves as they fall from the trees, the simple pleasure of a piping hot cup of tea in front of a roaring fire and to top it off England reaching Rugby World Cup Final!
Not only is November packed with everything you need to get your senses ignited, it is also represented by two beautiful birthstones, topaz and citrine.
We’ve collated our 9 favourite facts about these beautiful gemstones:
1. In the UK, Topaz in its blue form is also the stone for 4th wedding anniversaries.
2. Citrine is a transparent yellow variety of quartz. It is found in shades ranging from pale lemon to golden honey and sometimes amber-brown.
3. The most popular colour of topaz is blue and it can be found in light, mid and dark tones known as Sky Blue, Swiss Blue and London Blue.
4. The most highly prized citrine stones are highly saturated yellow with little to no brown tones.
5. Topaz is highly durable, only diamonds, rubies and sapphires are harder on the scale of natural composition.
6. Records for the use of citrine as talismans & simple decorative gems date back as far as 300 B.C. in Greece.
7. The world’s largest blue topaz is on display in the Natural History Museum. At 9,381 carats it weighs just under 2 kilograms and has breathtaking clarity.
8. Topaz has perfect cleavage. In gemstone terms cleavage refers to the tendency of a stone to split cleanly along a distinct plane when hit, knocked or cut with force, like a piece of wood splitting along the grain.
9. Unlike topaz, citrine has no cleavage and mohs hardness rating of 7, meaning it is very hard to break or split, making it an extremely wearable stone in jewellery.
