Is the topaz natural or treated?

The listing calls the London blue topaz natural. London blue is a trade name for a dark blue topaz, and blue topaz is routinely heat- and irradiation-treated to reach that color, so ask Helzberg for the treatment disclosure before buying.

How big are the diamonds?

The four round brilliant diamonds total under 1/10 carat, so each is roughly 1.5 mm or smaller. They read as small sparkle accents around the topaz, not as a diamond feature.

What chain length does it come with?

It comes on an 18-inch chain, which sits at or just below the collarbone on most women. No shorter or longer length is listed.

Is $628.96 a good price?

That is the only price recorded, at Helzberg Diamonds as of November 5, 2026, so there is no recent low to compare it to. Compare it against similar 10K gold pendants with a cushion blue topaz and diamond accents before deciding.

Can it be worn every day?

Yes, but 10K gold is durable and the spring ring clasp is the weak point. Take it off for swimming, gym sessions and cleaning with harsh chemicals to protect the topaz and the setting.

What comes in the box?

Helzberg typically ships jewelry in a gift box with a polishing cloth. Confirm the packaging and any warranty terms with the store, since the listing does not spell them out.
