Opalescent sapphires are something from a fantasy world. Their unique look and interaction between light and color make them something to be in awe of.

What is an opalescent sapphire?

As all stones do, sapphires can have various inclusions impacting color and clarity. An opalescent sapphire has a multitude of microscopic inclusions, mainly being rutile (titanium dioxide), called “silk”. These inclusions cause the stone to appear opalescent in color, offering a dreamy, ethereal look that is one of a kind. No two opalescent sapphires are the same, making them a beautifully singular choice for a custom piece of jewelry.

Why choose an opalescent sapphire?

These stones are perfect for those searching for something truly inimitable. While many sapphires possess one-of-a-kind characteristics, opalescent sapphires feel as though they fell from a sun-kissed sky only seen in dreams.

Are opalescent sapphires valuable?

Typically, in commercial jewelry and gem trading, opalescent sapphires are not held to the level of prestige as their non-included counterparts. However, value discerned by commercial companies differs heavily from what we discern as valuable. At Caleb B Quashen International, we prioritize the unique, the obscure, and the stones that tell a story. Opalescent sapphires are just that.
