Thank you for viewing. This is a turquoise necklace. I have worn it 1-2 times. Only the adjuster (2 places) is K18WG. It is a used item stored at home. Thank you for your understanding. Material: Partially K18WG (18 karat gold) Color: Blue Decoration: Turquoise Accessories: No box/No guarantee *Since it is a natural stone, there may be natural scratches and inclusions. Also, slight color differences may occur depending on your browser, protective film, brightness settings, etc. It is a used item. Please consider this, acknowledging that there may be overlooked scratches. There is no box, so it will be wrapped in cushioning material for shipping. Returns after purchase will not be accepted to prevent switching.
