Jacob & Co. High Jewelry

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 United States. 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 diamond details, these watches have become a celebrity favorite. Jacob & Co. watches sometimes house over 30 carats of diamonds and other precious stones on the dial.

Tanzanite running out

20 years ago the Mirerani quarries, located in Simanjiro District of Manyara Region used to spew out large amounts of tanzanite. Tanzanite production has been drastically dropping, and like every other single source gemstone the deposit is being depleted. Its called a single-generation stone.

There seems to be no end in demand as it has become a favorite of many jewelry designers.
