Choosing a Gemstone

When it comes to gemstones, the possibilities may feel endless. With sparkling cuts and beautiful colors, many gemstones are alluring and set with tradition. We source these gems from vendors that meet the highest possible ethical, labor and environmental standards.

Sapphires

The word sapphire comes from the Latin sapphiru which means blue. Sapphires come in a rainbow of colors from the vibrant blue of the midday sky, to the navy blue of the night sky, yellow reflections of the sun, and the pink of dawn and dusk.

Sapphire is the birthstone for September. It is also a traditional gift for those celebrating 5th or 45th anniversaries. Sapphires are often associated with loyalty and dignity and are a favorite gemstone for royalty.

Sapphires belong to the family of minerals known as corundum. They are among the strongest natural gemstones in existence, second only to diamonds.

The most valuable sapphires are a mid color blue with a concentrated hue which remains constant under all lighting conditions. Sapphires of up to 2 carats are common. Larger sapphires of up to 10 carats are not difficult to find in a variety of colors.

Emeralds

The word emerald comes from the Latin smaragdus which means green. Emeralds come in various shades of green, from deep darkish green to soft green, fine grass green and light green.

Reflecting the color of spring, emerald is the birthstone for May. It is also a traditional gift for those celebrating 20th or 35th anniversaries.

Emeralds are relatively strong gemstones, registering 7.5 - 8 on the Mohs scale of hardness. While they are fairly resilient to knocks, they can be chipped or ; scratched.

Emeralds are often associated with magic and mystery. The color of nature, they are said to promote a calm and peaceful spirit.

Moissanites

Moissanite, also known as silicon carbide, was first discovered in minute quantities from particles carried to earth by a meteorite 50,000 years ago. It is now available as faceted gemstones in a large array of shapes and sizes. Unlike other brilliant stones that cloud and dull with time, Moissanite is guaranteed to never lose its optical properties. Therefore, it will be every bit as beautiful, fiery and brilliant generations from now as the day you purchase it.

Moissanite is one the most brilliant and fiery gemstones in the world. Possessing fire, brilliance and luster that far surpasses even that of a diamond. Moissanite twinkles and sparkles unlike any gemstone on earth. Composed of carbon and silicon. Moissanite is an alternative to a diamond. They get confused so often because they are practically indistinguishable by the naked eye. In fact, even under a microscope they are rarely different. A gemologist has to have a special tool to determine if a stone is a diamond or moissanite.

Rubies

The word ruby comes from the Latin rubens which means red. Rubies are found in shades of red, from rich darkish red to pigeon blood red and pinkish red. The red hue comes from traces of the mineral chromium. Ruby is the birthstone for July. It is also a traditional gift for those celebrating 15th or 40th anniversaries.

Rubies are extremely strong, registering 9 on the Mohs scale of hardness. They are as resilient as sapphires and only slightly softer than diamonds.

Rubies have been found all over the world, including in Myanmar (formerly Burma), Africa, Australia and the USA. The majority of rubies for sale at Israel.

The most precious rubies are those with a full, rich red color with just a hint of blue tones. Originally, the finest rubies were mined in Myanmar and it is from there that the term Burmese ruby began to describe the finest rubies. Rubies, because of their brilliant red hues, are often related to themes concerning the essence and vibrancy of life. If there is one gemstone that represents the passion of love, it is the ruby.

Alexandrite

Often described by gem aficionados as “emerald by day, ruby by night,” alexandrite is the very rare color-change variety of the mineral chrysoberyl. Originally discovered in Russia’s Ural Mountains in the 1830s, it’s now found in Sri Lanka, East Africa, and Brazil, but fine material is exceptionally rare and valuable.

Alexandrite is a birthstone for June, along with pearl and moonstone. Alexandrite is also the gem for the 55th wedding anniversary.

This gem provides dramatic proof of how much the light source affects color in gems.

Aquamarine

Named after seawater, aquamarine’s fresh watery hue is a cool plunge into a refreshing pool. Like emerald, aquamarine is a color variety of the mineral beryl.

Aquamarine’s name comes from the Latin for seawater and it was said to calm waves and keep sailors safe at sea. March’s birthstone was also thought to enhance the happiness of marriages. The best gems combine high clarity with limpid transparency and blue to slightly greenish blue hues. Like many beryls, aquamarine forms large crystals suitable for sizable fashioned gems and carvings.

Aquamarine is the birthstone for March and the gem of the 19th wedding anniversary.

Garnet

Garnets are a set of closely related minerals forming a group, with gemstones in almost every color.

Red garnets have a long history, but modern gem buyers can pick from a rich palette of garnet colors: greens, oranges, pinkish oranges, deeply saturated purplish reds, and even some blues. Red garnet is one of the most common and widespread of gems. But not all garnets are as abundant as the red ones. A green garnet, tsavorite, is rarer and needs rarer rock chemistries and conditions to form.

Garnet is the birthstone for January and the gem for the second anniversary.

Morganite

Morganite is the pink to orange-pink variety of beryl, a mineral that includes emerald and aquamarine.

Morganite’s subtle color is caused by traces of manganese. Because morganite has distinct pleochroism—pale pink and a deeper bluish pink—it’s necessary to orient the rough carefully for fashioning. Strong color in morganite is rare, and gems usually have to be large to achieve the finest color.

Tanzanite

Lush blue velvet. Rich royal purple. Exotic tanzanite is found in only one place on earth, near majestic Kilimanjaro.

Found in just one place on earth, tanzanite is a relatively recent discovery. This blue variety of zoisite was named for Tanzania, the country where it was found, by Tiffany & Co. Because crystals show different colors depending on viewing direction, cutters can choose bluish purple or the more favored pure blue or violetish blue hue depending on how much weight they want to retain from the rough.

Peridot

Found in lava, meteorites, and deep in the earth’s mantle, yellow-green peridot is the extreme gem

The ancient Egyptians mined peridot on the Red Sea island of Zabargad, the source for many large fine peridots in the world’s museums. The Egyptians called it the “gem of the sun.” Today this gem is still prized for its restful yellowish green hues and long history. Large strongly-colored, examples can be spectacular, and attractive smaller gems are available for jewelry at all price points.

Peridot is the birthstone for August and the 15th anniversary gemstone.

Topaz

Honey yellow. Fiery orange. Cyclamen pink. Icy blue. In warm or cool tones, topaz is a lustrous and brilliant gem.

Topaz actually has an exceptionally wide color range that, besides brown, includes various tones and saturations of blue, green, yellow, orange, red, pink, and purple. Colorless topaz is plentiful, and is often treated to give it a blue color. Topaz is also pleochroic, meaning that the gem can show different colors in different crystal directions.

Precious topaz is a birthstone for November and blue topaz is a birthstone for December. Blue topaz is the gem of the 4th anniversary and Imperial topaz is the gem of the 23rd anniversary.

Spinel

The Black Prince’s Ruby. The Timur Ruby. For centuries, spinel, the great imposter, masqueraded as ruby in Europe’s crown jewels.

In ancient times, southeast Asia’s mines yielded exceptional large spinel crystals, which became the treasured property of kings and emperors, often passing through many hands as spoils of war.

Spinel was recently added as an August birthstone, sharing this month with peridot and sardonyx.

Tourmaline

Tourmalines have a wide variety of exciting colors with one of the widest color ranges of any gem.

Tourmaline’s colors have many different causes. It’s generally agreed that traces of iron, and possibly titanium, induce green and blue colors. Manganese produces reds and pinks, and possibly yellows. Some pink and yellow tourmalines might owe their hues to color centers caused by radiation, which can be natural or laboratory-induced.

Tourmaline is a birthstone for October, along with opal. Tourmaline is also the gem of the eighth anniversary.

Amora Gem

Since most people are familiar with diamond, we can explain Amora Gem by starting with a pure diamond. By taking a pure diamond, which is 100% pure carbon, and then removing every other carbon atom and putting a Silicon atom in instead, we end up with an Amora Gem's atomic composition (50% Carbon, 50% Silicon).

Because Silicon is a larger atom, the 50% carbon atoms have to shift to make room, but after the carbon atoms make room, you now have an Amora Gem.

(Note that to do this and grow an Amora Gem requires very extreme heat. These temperatures are found only around large stars or in extreme growth chambers that create the star-like environment. Diamond itself would vaporize in these star-like conditions which is why Amora Gem was only made available on Earth recently).

The 50% Silicon atom composition is what gives Amora Gem superior fire, brilliance and lustre versus diamond. Silicon is larger than carbon, so it is better able to bend light, and light bending and dispersion (measured as refractive index and dispersion index) is what provides a gem's brilliance and fire.

Rutilated Quartz

Rutilated quartz, is a type of quartz with needlelike rutile embedded in it. The rutile needles can be reddish, which is what rutile means in Latin, or they may be golden, silvery, or on very rare occasions, greenish.

Rutilated quartz is reputed to be an energizing stone that helps get energy moving on all levels. Intuitive sources say that it assists with mental focus. It is also said to attract love and stabilize relationships. Rutilated quartz said to be particularly effective for getting things moving energetically. It can help slowed chakras return to normal spin and balance.
