Material: Platinum 900, Chain 850 (stamped) Decoration: Diamond (0.775 carats) Gem identification certificate included. Chain is approximately 45 cm, adjustable type. The round ball has silicone inside, allowing for adjustment. (The last photo shows it at its longest length.) Purchased approximately 13 years ago at a department store. At the time, I didn't think much about it, just that I always wanted a cross pendant! I loved it and bought it, but when a Buddhist priest visited my family's home, I realized from a conversation that a cross pendant represents Christianity! Although I consider myself non-religious, I somehow lost the opportunity to wear it and it has been in storage ever since. This pendant has very beautiful diamonds that sparkle brilliantly, which is what attracted me to buy it. It's made of platinum, and I looked at many others, but the back is also plump. Inexpensive ones sometimes have the back hollowed out for no reason, so I was impressed with this one! Approximately 2 cm long Approximately 1.6 cm wide I would be happy if someone who likes it would purchase it. I bought it for 600,000 yen. This is the final price, without any discounts. For those who love diamonds and trust me.
