Diamond necklace 1 carat

This is a 14k white gold mined diamond ( not lab grown) necklace. I’ve had it about twenty years, and only worn it a few times. I purchased it from shophq back when it was shopnbc, and it was from Beverly Hills diamonds. It’s a cluster of diamonds and it equals 1 carat with round and baguette diamonds. The clarity I think is SI2, and the color is def or maybe ghi, but it seems colorless to me. Pictures don’t do this necklace justice and it doesn’t show just how much it sparkles. Always received compliments when I did choose to wear it. I paid about 5,000 for it when I bought it. It’s a three strand necklace and the chain is 18 inches in length. Feel free to ask any questions. It’s also hollow in the back and one of the pics show it. Also I added a pic of how it looks on a single box chain.
