Which looks more like real diamonds?

Neither uses real diamonds. The GLD chain uses CZ in a uniform round cut, which reads as a classic tennis chain. The 15CT uses mixed-cut stimulants that sparkle differently but look less uniform.

The 15CT has a sterling silver base under its plating, which generally holds up better than plated base metal. The GLD chain backs its craftsmanship with a lifetime repair guarantee, which offsets some of that.

Is the 15CT worth the extra?

It depends on price, which was not provided here. The 15CT gives more carat weight and a silver base; the GLD gives a lifetime guarantee and a classic look.

Which is better for everyday wear?

The GLD 3mm chain is lighter and simpler, so it stacks and layers easily. The 15CT is a statement piece better suited to occasional wear.

Which is better for a gift?

The GLD chain is the safer gift with its lifetime guarantee and classic style. The 15CT suits someone who wants a bold, art deco piece.

Do either come in different lengths?

The GLD chain is listed in 16, 18, 20 and 22 inch options. The 15CT is described only as collarbone length.
