The difference between 14K and 10K Gold is the percentage of gold that is contained in a piece of gold jewelry. 10K gold contains 41.7% gold and 58.3% alloy, which means it contains more alloy than gold and therefore a less expensive option. 14K gold contains 58.5% gold and 41.5% alloy and is usually the most popular choice for wedding rings and engagement rings. Pure gold is a soft metal that tends to bend and scratch very easily, so since 10K gold has the most alloy in it, it’s more durable/less soft than 14K gold.

In terms of the color, 10K gold looks slightly more pale than 14K gold but usually you won't be able to see the difference with your bare eyes.

One of the biggest appeals of getting a white sapphire center stone would be the fact that they are far more affordable than a diamond. Diamonds can start at $6000 for a 1 carat stone, whereas a Sapphire can star at $600 for a 1 carat stone.


Sapphires are a hard and scratch resistant mineral, so white sapphire engagement rings are very durable. On the Mohs Scale of Hardness, a sapphire is rated as a 9. This makes it the second hardest natural stone used in jewelry. A diamond, which is the hardest, scores a 10.

Size + Shape Availability

Both white diamonds and white sapphires come in about any shape and size, which leaves a lot of flexibility with the design process. Every one of our engagement rings can be made with the white sapphire or diamond of your choice.

Sparkle + Shine

A white diamond will sparkle more than than a white sapphire. Diamonds has more scintillation, which refers to the rainbow colors that you can typically see a diamond giving off. A white sapphire does not display any scintillation. However, white sapphires still sparkle in their own right. See the image above to reference the two side by side: the oval-cut white diamond is on the LEFT and the round-cut white sapphire is on the RIGHT.

Grading System

Unfortunately, a cut grading system for sapphires does not exist. White Diamonds on the other hand have grading for their carat size, clarity, color and cut.
