Top Questions and Answers About Diamond Necklaces
- While the price of a diamond necklace can range from a few hundred dollars to hundreds of thousands of dollars, you can find a gorgeous diamond necklace at any price point. A shimmering, single-diamond solitaire necklace is an affordable and beautiful piece of diamond jewellery, while an intricately adorned, diamond-encrusted eternity necklace will cost more.
- The worth of a one carat diamond necklace is largely based on the stone itself. The greater the clarity, cut, colour and carat of the diamond, the higher the value of the necklace. Higher quality one-carat diamond necklaces can fetch upwards of eight thousand dollars, while an equally brilliant one-carat, lab-grown diamond is far more affordable.
- A sturdy chain is your best bet for a diamond pendant—but that doesn't mean it has to be big and heavy. Cable chains are a popular choice for their solid construction and delicate appearance, and they're simple to repair if they break, increasing their longevity.
