This is an antique Victorian 10K Rose Gold stickpin with a magnificent Australian opal bezel set into the head. It is handmade, from an estate, and in excellent condition. It has been jeweler tested and is Guaranteed to be solid 10K rose gold with its original, natural, opal in place. The black connection mark that you see on the back is the soldering joint where it was made by hand using non gold solder for strength and durability. This opal head is absolutely gorgeous. The photos don’t come close to capturing all of the very deeps colors and flash in the stone. There are large patches of neon greens, aquas, and teals along with vibrant blues and purples. A well chosen and very eye catching stone was used in this pin. The dark photos come closest to true color but the actual colors are much more energetic and brilliant. The head measures 8mm or 5/16″ across. Size of entire pin is 2 1/16″ tall North to South. Condition is completely original, excellent, gently used, no damage or repair. The rose gold has patina consistent with its 130 to 140 year old age. The back of the head has one scratch that is on the surface only and could be polished out. The opal is also excellent. No cracks or chips or flakes or breaks. No inclusions. NOT a doublet. The is a most impressive opal for your antique jeweled stickpin collection. You can not find such fine quality opals like this today!!
