Sapphires of Didy, Madagascar

Didy is a town in Madagascar. It belongs to the district of Ambatondrazaka, which is a part of Alaotra-Mangoro Region. In late 2011 a new deposit of gem quality sapphire was found there.

The island is one of the poorest countries in the world, with 81 percent of the population living on less than $1.25 a day.
The deposit is 25km south-east of Didy. Reaching the mine takes two days of hard walking from Didy, the closest place reachable by bush taxi. Even getting to Didi is tough. It’s 300km from the capital, and less than a third of that distance is on paved roads.

The last 10 hours of the trek is through rain forest, climbing precipitous hills on boggy paths.

The rubies and sapphires found there do not need to be heat treated.
After falling a tree, locals found transparent blue gemstones. By June 2012 sapphires began sporadically arriving at the capital Antananarivo, brought there by gold miners.

The stones are of exceptional quality. Vivid in color, beautiful clarity and size, the Didy discovery is the most important recent ruby and sapphire discovery in the world.

Madagascar is rich with mineral deposits, but its people remain some of the poorest on earth.
Within days, hundreds of tents and huts rose in the forest. A massive rush ocured before the Malagasy authorities sent a force to expel the miners as the discovery was in Makira Natural Park, an area dedicated to conservation. Sapphires present an irresistible lure of quick riches for locals.
As many as 10,000 miners and precious stone traders from around the world raced to the eastern region to extract the stones and ship them overseas. As well as digging up the forest floor, they cut down trees for firewood and shelter in the hitherto untouched wilderness and hunted resident animals, particularly lemurs, for bushmeat.

Despite the mining being illegal on protected land, the Malagasy government is unable to control it. The government has banned foreigners from the area. Armed gangs are the rule of law and unreported crime is common.

Red Spinel

Spinel is highly sought after by gem connoisseurs with crystals in high demand among collectors. Red spinel is the most desirable, followed by cobalt-blue spinel, then hot pink and vivid orange stones.
Red spinel ranges from orangy red to purplish red, with pure red hues the finest.
A top quality 5 carat red spinel might sell for a tenth the price of an equivalent ruby. Pink spinel often sells for less than pink sapphire.
The most highly valued blue spinel colors parallel blue sapphire, with intense violet-blue to pure blue colors highly regarded. Eye clean spinel is more valuable than that with inclusions. The more visible the inclusions, the more the value drops.
Larger spinel sizes rise considerably in per-carat price.

Prices rise sharply for fine red, pink, and blue stones above five carats.

Jacob & Co.


12.95 carat fancy purple-pink radiant cut diamond engagement ring. IF clarity. $11.6m
Born Yakov Arabov, Jacob Arabo emigrated with his family when he was 14 from Uzbekistan to the US. At age 16, he enrolled in a six-month jewelry-making course, which he graduated four months later. By the time he was 17 he was designing his own pieces near New York City's diamond district.

30.11 carat natural fancy blue gray cushion-cut diamond mounted on a platinum setting. VVS2 clarity $20m .
Although he started out offering moderately priced, traditional jewelry, Arabo’s designs soon caught the eyes of celebrities, singers, and artists in the hip-hop and rap music world. In the early 1990s his clientele and business grew, and he became known as “Jacob the Jeweler”.

In 2005 he relocated to a storefront on East 57th Street. Jacob & Company has been producing luxury watches for a quarter of a century.

Perhaps due to the extravagance of the diamond details, the watches have become a celebrity favorite.

Jacob & Co. watches sometimes house over 30 carats of diamonds and other precious stones on the dial.
