Thank you for viewing. This is a K18 yellow gold and blue topaz necklace. The vintage-style decorations are lovely when viewed from the sides and back. The bale is hallmarked with "k18". Screw chain: Approximately 40cm Adjustable to -3.5cm shorter. The clasp has a K18 and Japan Mint inspection mark (hallmark). The chain and pendant top are detachable. Will not be sold separately. Pendant top size (excluding bale and round ring) Length: 15mm Width: 14mm Thickness: 9.4mm Bale: Approximately 8mm x 3mm Weight (total): 5.92g *Measurements are approximate. Please allow for slight errors due to the scale. Before listing, it has been cleaned with an ultrasonic cleaner (image 18) and a gold-specific jewelry cleaner, so I believe you can use it with peace of mind. The color is displayed to be as close to the actual item as possible, but please understand that there may be differences in color depending on your monitor environment. I don't think there are many scratches or scuffs visible to the naked eye, but there may be overlooked scratches, chips, scuffs, or dullness. Please refrain from purchasing if you are extremely concerned about the condition or if you are looking for a perfect item, as this is a USED product that has been in someone's possession and stored at home. We cannot accept exchanges or returns to prevent product substitution.
