Jar Chrysoprase

No verified biography was located for an artist named Jar Chrysoprase. The name appears to combine two separate and unrelated references that do appear in art market sources: JAR, the professional name of the Paris based jeweler Joel Arthur Rosenthal, born in New York City (exact birth date not confirmed in sources reviewed), and chrysoprase, a green gemstone that is also the title of a 1965 color screenprint by Josef Albers held at the Nelson-Atkins Museum of Art. Neither reference describes a person named Jar Chrysoprase, and neither should be read as biographical fact about this entry.

No exhibition reviews, catalog essays, or verbatim critical quotes referencing an artist named Jar Chrysoprase were found in the sources reviewed.

No auction record, sale, or lot attributed to an artist named Jar Chrysoprase was found in the auction databases and art press reviewed. Published figures for "JAR" jewelry sales at Christie's and Sotheby's, including reports of results reaching into the millions of dollars, refer to Joel Arthur Rosenthal, a different, well documented individual, and should not be attributed to this entry.

Collectors should treat the name Jar Chrysoprase as unverified. Nothing in this entry should be read as confirmation of a working artist, a specific artwork, or an active market. If primary documentation, such as a signed work, gallery invoice, or catalog entry, surfaces to establish a real identity, this profile can be rebuilt from confirmed sources at that time.
