Gemstones
Want to add some color to her life? A beautiful gemstone is a striking solution. Angara offers four varieties:
Ruby - She'll stand out in ruby's classic red hue. Made from the mineral corundum, the best color is a deep, pure red or slightly purplish red.
Sapphire - It comes from the Greek word for blue, but sapphire (which, like ruby, is made from the mineral corundum) is available in many colors, including pink and yellow. In the classic blue, a strong medium blue is most prized.
Emerald - Treasured by powerful women from Cleopatra to Elizabeth Taylor, the most valuable emeralds have a fresh, pure green - although a darker bluish green is also common.
Tanzanite - the velvety blue of Tanzanite is found only in the hills of Tanzania near Mount Kilimanjaro. Introduced in 1968, a tanzanite has blue and purple crystals, and shows different colors when viewed at different angles.
Buying tips:
~Color quality is key. The brighter and more vivid the color, the more sought after and valuable.
~The better the clarity, the better the stone. Like diamonds, colored gemstones exhibit internal characteristics known as inclusions. In general (though there are exceptions), the fewer inclusions in a gemstone, the more valuable.
~Expect to pay more per carat for a large gem than a small one. Colored gemstones are measured by weight, not size -- in carats, just like diamonds. But some gems, like emerald, ruby and sapphire, rarely come in large sizes, so those are far more valuable than their small counterparts.
~A good cut delivers the most brilliance and beauty.Colored gemstones reflect light, the same way diamonds do. So a quality cut makes a big difference in terms of brightness.
