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 and later adopted the professional version of his name: Jacob Arabo. 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.

Supermodel Miranda Kerr returns $8.1 million worth of jewels

Supermodel Miranda Kerr has returned $8.1 million worth of jewels gifted to her by an ex-boyfriend—who may have given them to her as part of a money-laundering operation.

The case surrounds Malaysian businessman Jho Low. Low bought her a 11.72-carat diamond pendant, designed by Lorraine Schwartz, for Valentine’s Day. That gift cost $1.29 million. He also allegedly bought her an 8.88-carat diamond pendant that was worth $3.8 million, and then bought her matching earrings, a bracelet, and a ring. The U.S. Justice Department is still looking for more than $1 billion in assets they claim were bought with money stolen from the Malaysian government.

‘Rockefeller Emerald’ makes $5.5m

An 18.04 carat Colombian emerald once owned by the Rockefeller family appears at Christie's Magnificent Jewel auction. John D. Rockefeller Jr. acquired the octagonal step-cut emerald in 1930. The American Gemological Laboratories (AGL) describes the jewel as "exceptional," adding that it's an "unusual combination of size, provenance, absence of treatment and quality factors [that contribute] favorably to its rarity and desirability."
The emerald was expected to sell for between $4 million and $6 million.

Pink Topaz

Blue topaz, the cheap gem that owes its color to irradiation, took the jewelry world by storm in the 1980s. The trade expected pink topaz could be just as inexpensive. It's one thing to coax deep-blue from cheap colorless topaz but another to coax deep-pink from uncommon precious topaz.
Topaz transformable into pink stones costs a lot more than topaz transformable into blue ones. The reason it costs more is limited supply. Not just of precious topaz, but precious topaz with an essential coloring agent: chromium, the same trace element responsible for red in ruby.

Topaz that can be turned pink seems only to come from Brazil, much of it from one mining locality: Oro Preto.
Pink Topaz is often cut to maximize rough yield, making calibrated gems suitable for jewelry exceedingly rare.

Pink Topaz looks great in low-light conditions due to its transparency and high refraction. With a Mohs’ hardness of 8, pink topaz is a good choice for everyday jewelry.
