Sovereigns frequently gave rings with their portrait or cipher to acknowledge loyal service and friendship. This ring bears the cipher of Louis-Philippe of France (reigned 1830-48). He was the last member of the Bourbon monarchy to reign in France. He abdicated during the 1848 Revolution and was replaced by Napoleon III.
The London Magazine of 1840 recorded Louis Philippe presenting a similar ring to the artist Thomas Shotter Boys "This gentleman has recently received a very flattering compliment from the King of the French. Having received from Mr. Boys, the beautiful Work of ' Picturesque Architecture in Paris, Ghent,' &c., just published, his Majesty very handsomely presented to him a splendid brilliant ring, with his cypher, L. P. in diamonds, on a blue enamel shield, bordered with brilliants, and surmounted by a crown of the same precious stones. It was accompanied by a letter, expressing his Majesty's desire that the gift should be received as a souvenir of the gratification which the Work has afforded him. We doubt not that the acknowledged taste of Louis Philippe, and his just appreciation of this unique production, will stimulate lovers of the fine arts to become possessed of so splendid a work."
