Rubies, The Scarlet Stones

Photo: moregems GIMME!!!
Let's look at the most fiery gem in the jewelry world: A red, red ruby. The other precious stones are diamonds, sapphires and emeralds. Of the 4 gems, diamonds are the most common in nature, with sapphires, rubies and emeralds being rarer in the order listed.

 The name ruby literally means red in Latin (from the word "rubens"). Just like their sapphire brothers, ruby sisters consist of the mineral corundum, except rubies get their vibrant red color from trace amounts of the element chromium. (On the other hand, when titanium and iron are added to corundrum, the resulting blue gem is called a sapphire. Get it?) As corundums, both rubies and sapphires are one of the hardest stones, rating a 9 on the Mohs Scale of Hardness, after diamonds, a 10.

The finest rubies in the world from Burma, now known as  Myanmar rubies, were banned in the United States for 5 years. The ban was imposed to fight an oppressive military regime, plus human rights violations, including child labor in the mines. That ban was lifted in the fall of 2016. The reason why Myanmar (or Burmese) rubies are so prized is due to their desirable hue called "pigeon's blood" -- a vivid red with a hint of blue.

Large transparent rubies are rarer and more expensive than diamonds (costing twice as much per carat). Know that (just like sapphires) there are few imperfect rubies in the world, so inclusions in rubies are acceptable as long as they don't affect clarity. "Silk" inclusions are commonly seen in rubies -- they are intersecting needles of the mineral rutile.

As much as I love rubies, I'm not too tempted to buy them these days. Why you may ask? A fine Burmese ruby averages $3,000+ per carat (depending on color and inclusions). But more affordable rubies sourced from other parts of the world (including the USA, Australia and Africa) are often too tiny, cloudy or pink in my humble opinion. What's the point of paying for those? I want a big clean pigeon's blood ruby, don't you? (But not enough to pay the piper, and now I worry about abuses in the mines also. So check before buying.)

In fact, most modern rubies have been treated to improve their color and strength. Treatments include heat, or lead glass filling (into fractures). While this improves the transparency of the stone, it also makes the gem look more expensive than it really is, therefore the information must be disclosed to a buyer and priced accordingly.

But. If you adore rubies feel free to buy a bauble in your budget to dress yourself up. At the end of the day, jewelry is a thing of beauty only and not an investment anyway. So if you love the scarlet stone, get one and wear it to your beating heart's content!♥♥♥

Irish Soda Bread: Sweet Or Savory?

Image
Photo by  All About Food I can't claim much Irish ancestry, but aren't we all Irish on St. Patrick's Day?  I do love meat and potatoes, Irish stew, cabbage, root vegetables and Irish soda bread.  I started making soda bread because it tastes similar to buttermilk biscuits, but you can substitute healthier ingredients: like butter instead of lard and whole grain flour in lieu of all white flour.  Soda bread is delicious served warm.  Here is my recipe: Irish Soda Bread For Savory Ingredients: 3 cups whole wheat flour 1 cup all purpose flour 1 ½ teaspoons sea salt 1 teaspoon baking soda 1 teaspoon baking powder 2 eggs, lightly beaten 4 tablespoons cold butter, cubed 1 ¼ cups buttermilk -  I use low fat (1.5% milkfat). optional: 1/3 cup caraway seeds For Sweet You will add  ½ cup sugar, 1 cup raisins. (= Irish American soda bread) Directions: 1. Preheat your oven to 375 degrees F. 2. Stir the first 5 dry ingredients together in a mixing bowl. 3. Mix ...

PureFlow Q17 Fan

Image
The PureFlow Q17 fan is an investment, but at $99 it is about 1/3 less than other bladeless fans. Although compact, it puts out a powerful airflow. In lieu of only 3 fan speeds, there are 12 speeds. You can easily sit it on the floor, or on top of a piece of furniture. And sans blades, no need to worry about curious children or pets getting hurt. The fan is designed to circulate air throughout an entire room. It vertically tilts 90 degrees and has a 90 degree horizontal oscillation. This keeps the air flowing in every direction. Moreover, a heavy smoker lives above me, who oddly enough, smokes at 3:00ish am and 5:30ish am every morning. What a nightmare at such vulnerable hours. The cigarette smoke migrates into my apartment and makes it hard to breathe, so I sleep with the fan sitting on a foot stool, pointed up at the ceiling. It does only some good (and I worry she will burn the place down during hours the rest of us are sleeping.) How I wish this mindless,   nocturnal being ...
