I want to word this really carefully this was sold but I decided to cancel the sale because I want to send it to the gia. it's going to be very expensive to do that. so I'm going to word this very carefully. and I apologize to the buyer. after Thanksgiving I took this beautiful piece to the jewelry store. I was going to have it sized they thoroughly tested it. the top was testing as a moissanite. but the owner of the jewelry store which is very knowledgeable over 40 years. he's tested it and he tested under the bezel and it lit up 100% diamond. he is a million percent sure it is a diamond. this is a lab diamond but it may test as a moissanite. please research designer may test as mosanite. the setting alone is worth $4,000. and he estimates the diamond / moissanite in it to be worth over 7,500 and more it's flawless. I'm selling this beautiful piece because I want to give my kids a Christmas. it's been a rough year my youngest daughter dealing with health issues. trying to take the strain off my husband . just the other day when my husband got home from work I found him crying in the car. because we are really struggling. it breaks my heart and I want to help him . please let me know if there's any questions I will include my Jewelers card I really want to give my children a Christmas
