Two Of Christie’s 2014 Magnificent Jewels

Christie’s, the famous New York City auction house, is holding their annual Magnificent Jewels auction on April 16. Always a highlights of the spring calendar in the diamond world, last year’s auction featured a 34.65 carat Fancy Intense Pink diamond that ended up selling for $39.3 million.

The high end pieces for this year’s auction include a pair of Internally Flawless diamond ear pendants of over 22 carats each, a 40.43 carat oval-cut diamond and a 50.05 carat Flawless briolette diamond.  However, a couple of sparkling colour diamond pieces by JAR really caught our eye.

1.  Historic Fancy Yellowish Green Diamond


Three separate angles of a 2.49 carat fancy yellowish green diamond set with an old-mine cut surround with a single-cut diamond gallery and hoop, mounted on platinum.   Early estimates are that this could sell for as high as half a million dollars. The diamond itself was formerly owned by Eliza Branicka, the wife of 18th century Polish romantic poet Zygmunt Krasinski.

2.  Oval-Cut Fancy Intense Yellow Diamond


A 15.75 carat oval-cut, fancy intense yellow diamond set on a pave diamond thread mount and mounted on platinum.   Christie’s estimates that it should sell between $500,000 and $700,000. The piece was formerly the property of Brazilian philanthropist and socialite Lily Safra.   One of the richest women in the world, Safra owns what is considered the second most expensive home in the world Villa Leopolda on the French Riviera.

Jewels by JAR

What makes these two colour diamond pieces even more special is that they are from jeweller Joel Arthur Rosenthal, better known simply as JAR.   His shop, located in Paris’ Place Vendôme, has no windows, no signage and no set hours.   He caters only to the worlds’ elite and does so without advertising or a social media presence.  The mere mention of his name means that what Christie’s estimates for these two colour diamond rings could end up being a very conservative guess.
