Proprietary Crafting Techniques

Every piece of GURHAN Jewelry is engraved with the GURHAN logo, the hallmark of the metal purity, as well as a unique item number.  As of April 2022, we are including a code as part of our hallmarking process. This code will indicate Gurhan’s production techniques. This code will be engraved after the item number. See image below.

Below are the technical codes we use and engrave after each item number:

(S) Solid If a piece is solid, it is not hollow and it does not contain any non-metal fillers or any other metal.

(NMF) Non-Metal Filler If a specific design is in need of physical reinforcement due to the softness and bendability of 24K gold, we use proprietary non-metal fillings to ensure the integrity of these pieces. This method was used by the Anatolian goldsmiths of the Byzantine period (third century AD to 15^th century

(H) Hollow Many of Gurhan’s designs are constructed as tubes or beads .  These components are considered to have hollow spaces, mostly for threadings, hoops and chains etc…

(GF) Gold Filled This is a technique Gurhan uses for some of his silver collections. The process involves attaching a layer of 24K gold onto sterling silver.  When properly cared for, 24K gold filled jewelry can last a long time.

(V) Vermeil This is a technique Gurhan uses for some silver collections.  This is a chemical process called electrolysis.  Basically, with the help of a chemical gold solution (known as king’s water), silver will be covered by pure gold about 2.5 to 3 microns.

(R) Reinforced Gurhan uses a flexible stainless steel wire spring in his Spring collection.

If you have purchased an item that does not contain this code, it was likely produced prior to April of 2022.  Please contact concierge@gurhan.com for additional details on your item.
