ANTIQUE SALAMANDER BROOCH.
by Rebekah V. Wise
Okay, she may actually be a newt, but this winsome girl is mostly prized for the bright green racing stripe of Russian demantoid garnets down her back.
Originally from a pre-revolutionary source in the Ural Mountains of Russia, demantoid is the green gemstone variety of the mineral andradite, the most expensive and rarest of the garnets. So-named because of their diamond-like refractivity and unusually high dispersion (higher than diamond and often visible as rainbow-colored flashes of light).
Demantoid garnets were a favorite gemstone of jeweler Peter Carl Fabergé. Many of his jewelry designs for the Russian Imperial Family featured these lively bright green stones. Total demantoid weight is 4.00 carats. Surrounded by 53 Old European-Cut diamonds for a total
diamond weight of 1.20 carats. Crafted in 18k yellow and white gold. Don't let her slip away!

Pricescope.com, the world’s busiest gem forum has been sold. I was recently introduced to the new president and CEO is Andrey Pilipchak. Andrey took over in July of 2007. During a casual conversation with Pricescope founder Leonid Charny.
“He mentioned he is a little bit tired of running Pricescope and before you knew it I became the new owner.”
Pricescope is the six hundred pound gorilla on the internet. The site boasts 31,000 registered users. Pricescope’s reach contrasts with forums such as Gemologyonline with 1600 registered users and yourgemologist with 6,100 members. “We average about 1,500-2,000 posts a day.” Andrey said in a recent interview, “with over 350,000 unique visitors per month.”
Ranking the Forums:
According to Alexa.com the major gem forums rank as follows: It shows Pricescope far in the lead:
1. Pricescope.com 42,927
2. Diamondring.com 126,540
3. Yourgemologist.com 240,066
4. Gemologyonline.com 240,334
Rating the gem forums is sort of like comparing apples to pomegranates. Each of the four sites mentioned have a different focus and attract different sorts of users. Pricescope members are predominantly consumers looking for information or collectors who want to show off their most recent gem and jewelry acquisitions. Diamondring.com (formerly diamondtalk.com) is a commercial site masquerading as a forum and is mainly about selling diamonds. Yourgemologist and Gemologyonline are oriented toward student and professional gemologists, lapidaries and gem dealers.
Pilipchak graduated from Bradley University with a BS in Electrical Engineering. He has worked in the software engineering field for over 20 years as a developer and manager, skills that should be very useful to him in his new role.
The Brotherhood of the Banned:As Pricescope became more powerful it developed a reputation for banning members, particularly professionals, over relatively minor infractions of its rules. I, myself, was banned by the former owner for mentioning and posting a link to another forum. See GemWise: Rating The Gem Forums.
Pilipchak has taken what he calls a “liberal approach” to past transgressions. “I look at them on a case by case basis.” He must truly be a liberal; he invited your’s truly back on the site. Several other formerly banned individuals have also been reinstated.
“I am basically one person and I have a lot to do.” Pilipchak has a very small staff and his wife helps him out. How is he doing? “I am enjoying it so far. It is a wonderful venture and I feel it has a lot of room to grow.” We wish him luck. Stay Tuned!
Price Watch: Gemstones:
Gem prices, particularly those for larger finer gems, have risen dramatically in the past three years. Over the past thirty years I have seen a number of ups and downs in the market though you will never get a dealer to admit that. For dealers, prices are always up and finer stones are always more difficult to find.
Another theory, gem prices have always about the same. Apparent price differences are simply the result of fluctuating values in paper currency. This somewhat cynical view certainly seems to reflect the current market. Take the D flawless diamond. Stones over five carats, particularly the rare type IIa diamonds are up about40% at the wholesale level in the past year. Two years ago ruby prices made a great leap forward. This correlated with the decline of the dollar against the Thai bhat.
Colored diamond prices including prices for the relatively available fancy yellow and brown stones have gone along for the ride. I recently priced a 2+ carat blue with the coveted "fancy vivid" grade from GIA; at over $500,000 per carat wholesale. With 5+ carats bringing between 1.3 and 2 million per carat that should not be surprising. Colored diamond expert Stephen Hofer put it succinctly: "Prices are crazy" he told me.
In other markets, heat-treated blue sapphire is currently in good supply. Prices have declined a bit a fine stones are available at perhaps 10% less than a year or two ago. Prices for fine natural (unheated) stones have increased and stones are becoming more difficult to find.
Rarity coupled with demand is another important factor driving price increases. Emerging gems, such as the new finds in peridot, cuprian tourmaline, spessartite garnet and demantoid garnet have been rising slowly but steadily in price over the past five years. Spessartite garnet, finer pure orange stones above 5 carats have increased by about $100-200 per carat annually. Peridot over 5 carats is up in price. Lighter, brighter pastel green-blue tourmaline, whether cuprian or not, have also increased substantially in price.
The new greenish-blue to blue Mozambique cuprian (copper bearing) tourmaline have not increased in price because a consortium of dealers managed to establish a high price for the stone right out of the gate. As of this writing, prices for Mozambique tourmaline are stable with perhaps a bit of softness in the market due to the economic downturn in the US.
As I mentioned earlier, prices for fancy color diamonds have skyrocketed. Colored diamonds are the only diamonds that are truly rare. Diamond is so hard, the atomic lattice so tight, that few impurities, the sources of color, can penetrate the crystal lattice. One of the three atoms in Nitrogen. This is the source of yellow in diamond.
Queen of the colored diamond is the Fancy Vivid gem. #7448 this 0.70 carat pear shape has been graded Fancy Vivid Yellow-Orange by the Gemological Institute of America's laboratory (GIA-GTL). Yellow diamonds incline towards either orange or green the two colors adjacent on the color-wheel. Of the two possible secondary hues, orange is preferred. Technically this is an orange diamond but to my eye this gem has just the right mix of yellow and orange to give it a truly sun-kissed glow.
The stone was purchased before recent price increases in is therefore available at a reasonable price. The stone is particularly well cut and completely eye-clean.
