Description
Deep purple amethyst takes center stage in this cushion amethyst and diamond necklace, set in antiqued sterling silver with a vintage feel. The stone is a natural amethyst, heat-treated, cut in a checkerboard pattern that catches light across its surface. A small round natural diamond adds a quiet accent beside it. The textured silver pendant hangs from a bail on a wheat-pattern spiga chain, closed with a lobster clasp. Wear it with a charcoal sweater or a black dress for a pop of rich color. A thoughtful gift for a February birthday.

Are the amethysts in these necklaces natural or treated?
The product details list whether each stone is natural or lab-created. In general, amethyst is a purple quartz, and heat treatment to deepen or even out its color is common and standard in the trade. Check the individual listing for the stone's specifics before you buy.
Which amethyst necklace styles are most popular?
Simple sterling silver solitaires lead the list. Round, oval and cushion amethysts in bezel or accent settings come first, followed by teardrop, swirl circle and leaf dangle designs. Styles with diamond or white topaz accents also appear near the top.
What affects the price of amethyst necklaces?
Metal, stone size and added accents set the price. Sterling silver and 14K yellow gold differ widely, and larger amethysts or diamond and white topaz accents add cost. Chain length and design complexity also matter. Use the Price filter on this page to set a budget.
Which amethyst necklace is best for everyday wear?
A single bezel-set round or oval stone is the easiest daily pick. The bezel rim surrounds the amethyst, so it snags less on clothing. Amethyst is fairly hard but can scratch, so store it separately. See our jewelry care tips.
