Princess Eugenie's Engagement Ring

Princess Eugenie coupleThe Royal Family is known for their beautiful colored gemstones and Princess Eugenie (daughter of Sarah, Duchess of York) is the latest to make news with her ring. Boyfriend Jack Brooksbank proposed with a rare sapphire and diamond engagement ring.

Princess Eugenie engagement ringThe center stone is an oval-shaped pinkish orange padparadscha gemstone, which is one of the rarest of all sapphires and typically originate in Sri Lanka but are also found in Madagascar and Tanzania. The sapphire is surrounded by a halo of small diamonds and the mounting is a vintage-style design in yellow and white gold.

Padparadscha is a derived from a Sinhalese word for “aquatic lotus blossom” with a beautiful salmon color. The color for the padparadscha sapphire can range from a salmon color with a pinkish hue to an orange hue. It is difficult to find a padparadscha over two carats in weight. When one is found it is considered exceptional and extremely rare.

Padparadscha gemstonesPadparadscha sapphires from Madagascar are at times heat treated to intensify their pink coloration. They are heat treated at very low heat temperatures, whereas padparadscha stones from Sri Lanka will be heat-treated at higher heat temperatures when heat-treated. The heat-treated padparadscha stones from Madagascar are often recommended over the ones from Sri Lanka because of the temperature they are treated at.

White Metal for Engagement Rings

Clients often ask us what type of white metal is best for engagement rings. The traditional choices are 14-karat white-gold (58.5% gold), 18-karat white-gold (75% gold), and platinum (95% platinum).

To produce the white color, white gold contains alloys such as silver, manganese, palladium, rhodium and nickel. When nickel is used in the alloy mix, it can cause allergic reactions in some people.

White gold rings are usually rhodium plated. Rhodium is a very white, reflective, and hard metal so provides an excellent surface for engagement rings. As rhodium is a plating, it will wear off with usual wear over months or years depending on the wear. The rhodium can be reapplied at most jewelry repair shops for a relatively small fee.

Platinum is a very durable metal and does not cause allergic reactions. However, platinum is relatively soft so tends to get dull and scratched over time, even more than white gold. As a result, it requires regular polishing to keep it shiny.

Our favorite metal for engagement ring uses a special 18-karat white-gold that contains a palladium alloy so is whiter and more scratch and bend resistant than platinum. Since the 18-karat white-gold stays shinier and is stronger than platinum, this is what we recommend to our clients. For clients who like a more antique look, the duller patina look of platinum is the way to go.
