Celebs Show True Blue Loyalty with Brilliant Sapphire Engagement Rings

Sapphires are precious gems with striking, rich blue hues. The sapphire symbolizes loyalty, making it ideal for diamond engagement rings. Trend-setting celebs have been spotted wearing sapphire engagement rings. Here are a few with noteworthy blue baubles:

Kate Middleton won more than Prince William’s heart – he also gave her his mother, Princess Diana’s, sapphire engagement ring. The 18-carat oval gem’s opulence demands attention. Small white diamonds line the brilliant blue stone.

Javier Bardem proposed to Penelope Cruz with a vintage 3-carat sapphire engagement ring. The gleaming gem stone is set off by smaller white diamonds lining the round center stone.

Ivana Trump was presented with a Kashmir sapphire engagement ring by beau Riccardo Mazzucchelli.

Kashmir sapphires come from the famed Kashmir mine in the Himalayas. Kashmir sapphires are prized for their intense hues of blue, even tones and their rarity. Kashmir sapphires make up less than 1 percent of sapphires mined in the world and usually go directly to museums or private buyers.

Other celebs to brandish Kashmir sapphire engagement rings include Kristie Alley, Susan Sarandon, Sara Ferguson, Heather Mills and Judith Nathan (wife of former New York Mayor Rudy Guiliani).
