A diamond heart pendant that says it for you

Questions and answers

Is $570 a good price for a 0.50ctw diamond heart necklace?

It is reasonable for 14K white gold with a half carat of diamonds, where similar pieces often run $500 to $900. With only one new listing at $570 at Marks Jewelers as of November 7, 2026, there is no lower new price to compare.

What diamond quality should I expect at this price?

At $570 for 0.50ctw in 14K gold, expect small diamonds in the G–I color, I1–I2 clarity range. The listing does not state grades, so ask the seller for them before buying.

Is the chain included?

A pendant like this normally ships on a matching 14K white gold chain, often 16 to 18 inches. Confirm the chain metal, length and clasp with Marks Jewelers before ordering.

Can I wear it every day?

Yes, but 14K white gold is soft and the rhodium finish dulls with wear. Take it off for showers, swimming and gym sessions, and plan on re-plating every year or two.

How does it compare with a solitaire pendant?

A 0.50ctw heart spreads its diamonds across the shape, so it sparkles broadly rather than in one stone. A single half-carat solitaire would cost more and read as a different, more formal look.

When is it cheapest?

Diamond pendants usually dip during holiday sales and post-Valentine's clearance. With one new listing, watch whether Marks Jewelers discounts it rather than expecting a price war.
