The 3 Millimeter Guilloche Hand Engraved Unisex Comfort Fit Wedding Band ! Talk about a unique and one of a kind finish on a ring! Ziamond is excited about this new and exclusive design in comfort fit wedding bands. The Guilloche hand engraved wedding band is a hand engraved process that is done by a Master Craftsman, skilled in hand engraving and etching. This technique was originally created by the French jewelry designer Louis Francois Cartier. No two bands are exactly the same and all the work is done by hand. Guilloche is a bright cut ridged finish that brings out the true beauty in the gold or platinum. It adds shimmer and shine to your band, almost never needing polishing and never shows scratches or dents. This is a lifetime finish. Available in widths from 3 millimeters to 10 millimeters. This finish can be done to 14k gold, 18k gold or platinum. This design is unisex and makes a great his and hers set. All Guilloche hand engraved bands are comfort fit with a soft curve on the inside making the ring extra comfortable.
