This is a TASAKI Akoya pearl necklace. I wore it only once for a wedding and have kept it carefully stored, so it is almost unused. The length is approximately 42cm. The pearl diameter was measured by TASAKI, with the center being 7.5mm and the smallest part being 7.2mm, which classifies it as a 7mm necklace. I purchased it from a TASAKI salesperson I know at the Regent in Hong Kong. It was a bit more expensive than in Japan, but I bought it because it had pure white pearls. Of course, all purchase certificates etc. are included, and thread replacement is also available for free at TASAKI in Japan. 7.5mm pearls are a size that is becoming increasingly valuable year by year due to demand and the effects of red tide. I am hesitant to sell it, so I am not considering a price reduction. It is a beautiful pearl that can be used for formal occasions as a lifetime piece. Please feel free to ask if you have any questions. - Brand: TASAKI - Material: Pearl - Color: White - Design: Necklace - Accessories: Certificate, Box - Condition: Unused - Clasp: Silver Thank you for viewing.
