Heat Treated Stone Helps Endangered Humans Survive

There's No Place Like Home

The desire and ability to exploit our environment and to utilize and improve the natural materials we find is rooted in our deepest past, and is in fact, part of the reason we are here today.

I was absolutely fascinated by an article in the August 2010 Scientific American, When the Sea Saved Humanity, that describes findings from an archaeological dig on the Horn of Africa. According to author Curtis W. Marean, his excavations in caves near Capetown show the presence of a small band of early humans during the Ice Age known as Marine Isotope Stage 6 (MIS6).  Somewhere between ~195,00 to ~123,000 years ago, because of the cold dry climate, early Homo sapiens on the mother continent of Africa suffered a severe population crash– the population plummeted from more than 10,000 to a few hundred breeding individuals.

Peridot- the “I don’t like my birthstone” Birthstone, Part 1

August 11th, 2010 by James L. Sweaney, CGA, FGA. GG
7.56 ct. Burma Peridot

7.56 ct. Burma Peridot

This is the first of the well received 3 part series we posted about peridot last year.  And the good part is that since we’ve had the peridot shown above for over a year, it’s time to find a home for it– til the end of our Famous Annual Clearance Sale, Saturday, August 14, you can buy this fabulous gem for 30% off!

We often hear statements like “I don’t like my birthstone” from folks born in August. In most cases, these people have never seen a really good peridot, so we make it our mission to show them gorgeous gems like this magnificent Burmese Peridot.

Peridot, pronounced pear-eh-doe, is a magnesium iron silicate mineral that is found numerous locations around the world, including Burma, Sri Lanka, China, and Pakistan. In the United States, Hawaii, North Carolina, and Arizona are sources for peridot–the San Carlos reservation in Arizona is currently a major commercial producer of good to better material.  The gem is often associated with volcanic activity, as evidenced by the famous Green Sand Beach of Hawaii, colored by myriad grains of peridot.

Another name for peridot is olivine, referring to the slightly brownish olive green color of many peridot crystals. The color of the best peridot ranges in tones of light to medium greenish yellow to warm green, with no brownish overtones. The color of peridot shows best in incandescent light–the green is rich and inviting and yellowish tones are less apparent–so it has the nickname “Evening Emerald.”

Peridot may have typical inclusions that resemble “lily pads,” but it is a gem that is frequently very pure and transparent. It takes a good polish and has a fairly high refractive index, so well cut peridots capture light very effectively. Since its color is not dark, peridot is known for its very bright eye catching sparkle.

Another characteristic of peridot is that it is never treated for color or clarity–it’s a gem that is totally natural. Interestingly, peridot is the only gem that has been found in meteorites. We often see peridot in estate jewelry-it’s bright color and sparkle, reasonable price, and ready availability have made it a jeweler’s favorite for centuries.

Peridot forms well shaped crystals of good size, so large gems are not rare in the market place. Prices for peridot are relatively modest– ring sized stones, from 1 to 5 carats, retail for as little as $10 per carat for the lower quality commercial grades. The very best bright apple green stones may bring as much as $350 per carat up to 5 carats. Larger stones in the 5 to 10 carat class that are suitable for beautiful jewelry can be purchased for $100 to $400 per carat. Premium museum quality large gems may top out at $700 per carat or more.

Peridot, a gem of good size and great beauty at reasonable cost, is one of the true treasures of the gem world. We’ll follow up with more blogs about folks who didn’t like their birthstone before they came to Mardon!

Correction- Reader’s Choice Balloting- Vote for Mardon

July 20th, 2010 by James L. Sweaney, CGA, FGA. GG

In our recent blog about voting at the annual Reader’s Choice survey at the Riverside Press Enterprise, we posted a link to the online ballot so you readers could vote easily. We just found out today from a client who tried to vote that the posted link didn’t work.

The link was copied directly from the July 11 Press Enterprise article– guess it’s their error. We fiddled with the original link, trying to link to the ballot page directly from this blog and found out you can’t get there from here! Some arcane web stuff that we can’t figure out– may have to do with the newspaper protecting it’s content.

If you want to vote, copy and paste this link into your browser exactly as you see it– no http // etc.

A One-of-a-Kind Filigree Engagement Ring

July 3rd, 2010 by James L. Sweaney, CGA, FGA. GG

We completed a most beautiful engagement ring a while back but weren’t able to post this blog till now. It was one of the most challenging projects we’ve ever done!

Our clients Megan and Mike, big fans of antique and period jewelry, fell in love with a 1920’s Art Deco platinum ring in our estate department, set with a dazzling one carat Old European cut diamond. We showed them several loose period cut diamonds, but this particular stone had so much life and sparkle they decided to buy the piece, use the stone for her new ring, and save the mounting for later.

Platinum Art Deco


Megan had a general idea of what she wanted– the design had to be lacy and delicate, with triangle-shaped natural blue sapphires on each side of the center. We asked her for design suggestions– she searched the web and came in with about 10 pages of pictures of period rings, all of which had elements that she liked! So the challenge was to get her to focus on what she really wanted.

After consulting with her, we concentrated on floral and ivy patterns, lots of hand engraving, and of course, the diamond and the blue sapphires, to create this first design. Read the rest of this entry »

Art Deco Jadeite Necklace- A Lesson in Appraising Jade

June 22nd, 2010 by James L. Sweaney, CGA, FGA. GG
Art Deco Jadeite Necklace

Art Deco Jadeite Necklace

We’ve been working on an insurance appraisal for this wonderful platinum necklace with diamonds and jadeite from the 1920’s and realized the piece has a lot to teach about grading and valuing jade.

Jade is not well understood by many folks. If I told you that jade can be one of the most expensive of all gemstones, you would probably be surprised– some pieces sell for well into six figures. Even jewelers who really know their way around the faceted stones have a hard time with jade, so we don’t often see really good jade like this necklace.

Jade is actually two different minerals.  Nephrite is the one we see in ancient chinese carvings and artifacts, while jadeite, discovered in Burma (Myanmar) in the early 1800’s, is the more valuable type used in jewelry.

The more vivid and translucent colors of jadeite, especially the emerald green known as “Imperial” or “Kingfisher” are highly sought after, especially in Asia and can sell for truly astounding prices. When we grade jade as a gemstone, we are usually talking about jadeite.

We grade quality in diamonds according to the 4 C’s.  When we grade quality in jadeite, besides grading the color as we do in other colored gemstones, we evaluate what I call “the 3 T’s”– translucence, texture, and tone.

Our Art Deco necklace is set with jadeite stones that blend well for color, but we can see different examples of the 3 T’s. Read the rest of this entry »
