Gemstone Details


Centuries ago, in Sanskrit writings, spinel was called the daughter of ruby, adored, yet somehow different. The Crown Jewels of Great Britain are graced with spinels and have resided in the regalia of kingdoms throughout history.

Found in Myanmar (Burma), Sri Lanka and East Africa, spinel comes in a variety of colors including oranges, pinks, blues, lavenders, mauves and vivid reds. While common in sizes up to two carats, larger gemstones can also be acquired. 

Spinel is thought to protect the owner from harm, to reconcile differences, and to soothe away sadness. However, the strongest reasons for buying a spinel are its rich, brilliant array of colors and its surprising affordability.

One of the most under-appreciated gemstones, spinel is coveted by collectors and gemologists for its range of hues and spectacular optical properties. Spinel was recently added as an official birthstone for August, raising its exposure to new heights. Recognized and prized for its hardness, brilliance, and unlike many other gem types, spinel is rarely treated or enhanced in any way. Many believe the name spinel comes from the Greek word for ’spark’. This name suits spinel well since it is a singularly refractive stone and is formed with cubic crystals similar to diamond, which gives this gemstone remarkable brilliance and fire.

Spinel is the birthstone for August and gift for the 22nd wedding anniversary.  


Hauyne is an extremely rare mineral and even rarer as a faceted gemstone; first discovered in the early 19th century in southern Italy. A member of the sodalite group of minerals, it is commonly found in volcanic areas, such as among the Vesuvian lava flows on Monte Somma. It was named for the “father of crystallography,” Abbé Rene Just Haüy. Hauyne is noted for its electric blue color, although it has been found in other colors, such as white, grey, yellow, green and pink. It is also noted for its perfect cleavage and brittleness, ranked as a 5.5-6 on the Mohs scale, which makes faceting the material difficult and thus rare. It is one of the possible constituent minerals of lapis lazuli. Today the most well-known locality for hauyne is the Eifel Mountains of Germany.

Paraíba Tourmaline

Neon blue copper-bearing tourmaline was discovered in the hills of the Brazilian state of Paraíba, in the late 1980's. Various gemological laboratories performed testing on the new material and discovered that it was a natural elbaite tourmaline. Elbaite is generally achromatic, which means the crystals are colorless unless there are trace elements present in the chemical formula. In the case of Paraíba tourmaline, the crystals contain trace amounts of copper, which give the gemstones their unique and vibrant color and the reference of cuprian, which stands for copper-bearing. This variety of tourmaline was officially named "Paraíba tourmaline" after the state in Brazil in which it was discovered.

Their rarity is unmatched, as there is only one Paraíba tourmaline mined in Brazil for every 10,000 diamonds, and a fine quality Paraíba over three carats is virtually unheard of. A point to keep in mind is that copper bearing tourmalines have been mined in Mozambique, Nigeria and other localities, however, they are referred to as Paraíba-type tourmalines, because a true Paraíba tourmaline can only come from Brazil, making it all the more rare.

Color is perhaps the most important variable when comparing these stones, all other things being equal. Inclusions are to be expected and forgiven when judging fine stones, as long as saturation of color and brightness remain strong. Nearly every other shade of tourmaline is found in Brazil, however none has the vivid glow that distinguishes the Paraíba tourmaline. Colors ranging from bright turquoise to majestic blue-green to “windex” blue, it’s the incandescent glow that appears to light up the stone from within that makes Paraíba tourmalines incomparable to any other gemstone.

Tourmaline is the birthstone for October and the gift for the eighth wedding anniversary.
