LeVian Chocolate Diamond Royalty Tiara 1/2Ct 14K Ring & Diamond Band 1/8Ct 14K

I purchased this two Diamond Rings from Kay Jewelers a couple of years ago & paid over $2,500 for both rings. Recently took them to be professionally cleaned at Kay Jewelers and was informed by them that since then they doubled in price value. Both are Collectible pieces & they're part of the Le Vian Diamond collection. The Royalty Tiara Ring is 1/2 Carat total Chocolate Diamond weight 14K Strawberry Gold & the Diamond Band is 1/8 ct total diamond weight & 14k Rose Gold. Both rings are size 9.
