The gem in the photo is pretty much the ultimate Santa Maria Aquamarine. A few years ago this stone came into our hands—literally—and amazed us all. A fellow I know in Brasil owns one of the mines in the mining district which produces the Santa Maria Aquamarine of fame. He made this stone available and WOW what a stone! It is about 11+ carats and about the most intense aquamarine blue we’ve seen to date. Now, that being said there is a pretty wide range of color produced from those mines down to some colors more normally found in the aquamarine range. Natural products are like that: unique gifts from Nature all according to what was happening in the Earth at the time. If that stone were available in today’s current market it would be for sale for many times the asking price of when it was produced. Why??? There was production back then and several mines and miners were active. Since then many have given up. Mines in that mining district seem to be a lot like slot machines. Put the money in and you may or may not get a reward. Many times we’ve heard about miners giving up after running out of capital and the next guy in at the mine hits a big pocket of gems right after he starts up. What a business….
For a gem dealer nothing takes the place of going to the mining areas. The two gems you see pictured are ones we found by going to the right place. The cut stone is one piece of a small lot of 3 pieces we bought many years ago in Brasil. The color is truly amazing and truly a collectible color. The stone is over 10 carats in weight. According to prices seen fairly recently for similar (but not quite as good) gems—it is worth several thousand dollars per-carat. This is a color and size and clarity in Imperial Topaz very seldom seen available for sale
June is always a great month—sunshine, flowers, school is out, and Alexandrite is its birthstone (shared with Pearl that is).
Rarity is one of the hallmarks of gems. All gems are rare. For instance and by comparison gold is about 30+ dollars per gram. The most affordable gems match and surpass that easily (Amethyst, Citrine, and Red Garnet). Gold owes its price to its rarity. If gold were as available as iron or aluminum its price would also be per-ton and not per-ounce.
If rarity is a big deal in this world then Alexandrite (natural Alexandrite) is way underpriced even at prices I’ve seen listed. The prices I’ve seen large fine Alexandrite listed at wholesale would extrapolate to between $50,000 and $100,000 PER-CARAT retail—or more.
For our first 15 years in the business there was almost no quantity of good Alexandrite in the market. There were a number of stones from time to time mined in Sri Lanka that might be OK for size and clarity but their color ranged from dark muddy brown to dark muddy green. Not exciting. However, in 1987 there was a miraculous discovery of Alex (we’re friends now) in Nova Era, Brasil. Luckily we were in Brasil several times that year and got to see and buy large amazing Alexandrite gems in quantity. It was the proverbial kid in a candy store experience.
At the turn of this century there was a discovery of Alexandrite in India. This was welcome since the material from Brasil was largely out of the general market by then. The gem in the photo is from the Indian find.
