Sevan Biçakçi is a jeweler out of istanbul who creates pieces, primarily rings, with a distinctive Turkish flair. He won a 2009 Couture Design Award for his cufflinks in gold and silver with miniature paintings showing two views of Istanbul. He was profiled in Fashion Trend Setter in 2007 after he won a few awards. In the current collection are various rings utilizing gems with faceted outsides and a small form, perhaps a building cut internally. The most obvious of these designs is his "Hagia Sophia" ring, with the Roman church cut into the inside of a citrine. The citrine is then set in gold, pave set with brown and white diamonds which form an inscription in old Turkish (translation unknown). A second piece of a similar genre has a portrait of Mehmet the Conqueror in gold on the side of the shank and a small building of some sort cut into the white topaz of the main stone.
And one more from the same collection, less obviously "Turkish" than the rest, but I quite like the use of brown diamonds as color. The setting of cut stones upside-down is reminiscent of Renaissance diamond rings.
For his newest collection, Ida, Sevan has drawn from earlier periods of Turkish history with pieces drawing from the Greek era of Asia Minor. Mt. Ida is in the vicinity of ancient Troy, near the ancient city of Ephesus, cultic sanctuary of Artemis.
