A filigree ring is a ring that is characterised by intricate often ornamental designs. They are usually very delicate patterns that require incredible skill to cast accurately and therefore they can cost more due to labour costs.
They are often set without gemstones, because sometimes the intricacy of the design would detract or be detracted from by the setting of a gemstone. That being said, a filigree with a gemstone can be exquisite and become truely a beautiful ring. A filigree ring will normally require a wide set ring as there needs to be more metal to work with in order to then cut some away to create the design. This is not always the case however and money can be saved on the gemstone where money is spent on the weight of metal.
The most attractive thing with a filigree is the level of personalisation avaliable, as you can have anything from lacework design to a celtic design and other things in between. This allows a level of personalisation that helps to create a unique looking ring that can be both beautiful and elegant at the same time.
Another option with filigree rings is a two or tri-tone metal shank so, for example, platinum, yellow gold and rose gold could be interweaved in a lace pattern to create a striking and interesting design.
