14K Gold

14k Gold (White, Yellow & Rose)

14k Gold Statistics
18K Gold

18k Gold (White, Yellow & Rose)

18K gold contains a higher percentage of gold in its make-up and will wear faster than 14K gold. It is not as durable as 14K, and may yellow, chip, or even lose metal over time.

18k Gold Statistics


Palladium is an incredibly dense, durable, and hypoallergenic precious metal, and does not need rhodium plating for its strength or color, making palladium the perfect option for those who love the look, feel, and luxury of platinum jewelry, but prefer the lower price point.

Palladium Statistics


Platinum is one of the strongest and most durable metals used in jewelry. It does not have to be mixed with other alloys for strength, and like Palladium does not need to be rhodium plated to achieve its bright, shiny finish.

Because of its purity, platinum is also hypoallergenic, making it the ideal choice for those with sensitivities to nickel.

4 Prong Head

4 Prong Head

The 4-prong head is the most commonly used option for all center stones. It allows an increased amount of light to enter the diamond which maximizes its brilliance.

5 Prong Head

5 Prong Head

5-prong heads are traditionally used for Pear and Heart shapes. 5-prong heads will have a V-tip, where as a 6-prong head will not.

6 Prong Head

6 Prong Head

A 6-prong head will provide a larger center stone with added security due to the additional prongs. For smaller stones, the additional prongs may decrease the amount of light that enters the diamond, thus slightly reducing its brilliance.
