Birthstone Spotlight: October Opal

Opal three

If you were born in October, you are lucky enough to have your choice of two very colorful birthstones: Opal and Tourmaline. This month’s blog post focuses on Opal—the “Gem of Mystery.”

Opal has perhaps the most mysterious look of any gemstone—especially fine opal. Who would guess that a “rock” from the earth could look like a miniature version of the Northern Lights? The idea of something from the earth looking so ethereal is somewhat of a contradiction. The soil we tramp over in our everyday life is so “earthy”—brown, drab, lifeless, dull, and opaque.

Sapphire is a lot bigger subject than might be thought by the casual observer. For many years, many people thought sapphire was simply that very dark blue stone in small sizes offered by most jewelry stores as the September birthstone. Sapphire is certainly that, but ever so much more…

San Carlos mine in Arizona

Where in the world is peridot mined?

When I first got in the business the big source for peridot was Arizona. This material comes from the San Carlos Indian Reservation which is more or less 100 miles east of Phoenix. In fact, Laura and I traveled there to buy rough directly from the Native Americans. The material from San Carlos tends to be small and also tends to be included…

Famous Mogok Rubies of Myanmar

Myanmar ruby rawWhether you are born in July, are a collector of fine gemstones, or a jewelry devotee, the Mogok Ruby should be part of your lexicon. Fine Ruby is sometimes known as the “king of gems”. Ruby from this fabled area of Myanmar (Burma) is highly sought after.

Birthstone Spotlight: April Diamond

loose-diamonds

The word “Diamond” is probably the most emotionally charged word in the entire lexicon of gems. Diamond is the most sought after gem in the world. Whether or not the diamond deserves this pinnacle is up for debate, but the fact that the diamond sits on the pinnacle is not.

This is due to many factors:

1. Diamonds are beautiful to the eye.
2. Diamonds tend to last.
3. There are enough to go around. Well sort of…..
4. They are well promoted.

Birthstone Spotlight: March Aquamarine

AquamarineAquamarine is one of my favorite gems. Of course with me, talking about my favorite gemstones is like asking a parent about their favorite child—whichever one I’m thinking about or talking about at the moment is the favorite. Still, aquamarine is right up there in my true favorites.

Aquamarine—one of the many faces of beryl

One of the interesting things about aquamarine is its true rarity—due to the unique trace minerals that have combined with its underlying base mineral, Beryl, to produce its beautiful blue tone…

Birthstone Spotlight: February Amethyst

AmethystIn past blogs about birthstones we have been talking about gems that have their gemstone “label” in common with their mineral names. Gems like Garnet, Topaz, and Tourmaline are also the mineral name. In contrast, Amethyst is a color name for quartz, which is a mineral. Amethyst is the quartz in its purple color.

Quartz itself comes in at least several colors: citrine (yellow, orange and red), amethyst (varying shades of purple), ouro Verde (a chartreuse color), whisky quartz (brownish), smoky quartz (brownish gray), prasiolite (light bluish green), and Ametrine (naturally occurring mix of purple and yellowish gold. Some of the colors occur in nature and some are induced by man. Amethyst occurs naturally in nature.

If quartz itself were a birthstone we would be talking about all of the foregoing colors. But amethyst is plenty wonderful all by itself…

History of the Sancy Diamond

While many of us have heard of famous diamonds such as the Hope Diamond (45.52 carats), residing as a premiere attraction in the Smithsonian, and the Koh-I-Noor Diamond (105.60 carats), displayed in the Tower of London, few people are familiar with the Sancy Diamond.

Sancy Diamond 2The Sancy diamond has a long, mysterious and passionate history. The larger of the two diamonds that carry the Sancy name, it weighs 55.23 carats and is of a pale yellow color. The shield shape (pear) was said to be discovered before the year 1570. It is named after the French Ambassador to Switzerland Seigneur de Sancy. He was the owner during the last years of the 16th century. But the stone’s history runs deeper. The legend has it that Charles the Bold, also the Duke of Burgundy, owned the diamond. As fate would have it the gem was lost in battle about 1477.

Romanov Illustrated Volumes Jewelry

Two volumes of illustrated jewelry albums will soon be up for bid at the London auction house of Bonham. The albums belonging to Ksenia Aleksandrovna, the Grand Duchess of Russia, catalogue the jewelry items she received from 1880-1912.

The catalogue served to record the exceptionally expensive belongings of the daughter of Tsar Aleksander III and sister to Nicholas II. The albums also serve as a diary and report of who presented her with gifts and when they were presented. The catalogues contain color illustrations and information on the occasion the gift was presented.

For 32 years the albums recorded the development and evolution of style in jewelry design. Including antique pieces and eventually Art Nouveau and Art Deco the albums follow 32 years of life for Ksenia; from a young girl through the births of her seven children. Many holidays and life events were marked with custom designed jewelry pieces to honor the events. Fabulous items such as an exquisite emerald, ruby and sapphire sets along with a diamond necklace, tiara and the pear collier-de-chien were gifts from Grand Duchess’s parents.

These albums recording the provenance of the jeweled gifts will be auctioned at the Bonham House in London on November 30, 2011.
