Is the opal real and where does it come from?

The listing describes an Australian opal, a round 3mm stone. Australian opal is valued for bright play of color. Ask the seller for the stone's origin and treatment before ordering if that matters to you.

Is it solid gold or plated?

It is solid 14k or 18k gold, offered in yellow, white or rose. That means the color runs through the metal rather than sitting in a thin plating that wears off.

What chain length do I get?

The base length is 15 to 17 inches. Longer lengths are available for an extra fee, so confirm the final length with the seller before ordering.

Can I choose a different gemstone?

Yes. The maker says the design can be made with gemstones of your choosing. Contact them before purchase to confirm the stone, cut and any change in cost.

How should I care for an opal necklace?

Opal is softer than most gemstones and can chip or scratch. Store it separately, avoid knocks and harsh chemicals, and take it off before swimming or cleaning.
