The ring is expected to sell for $35,000 to $55,000. 
 
 
Diamond bracelet lovers will delight in the above platinum and diamond bracelet that features a total 265 diamonds. The stones are a combination of marquise-shaped, baguette and round diamonds, all G-, H-, or I-color and VVS-VS clarity.
 
The bracelet is estimated to sell for between $22,000 and $28,000. 
 
Speaking of bracelets, there are several bold cuffs from major jewelry houses on offer.
