14k Gold Plated
Our 14K gold plated collection is made with a base metal of brass or sterling silver (s925 - more below), coated in a layer of real 14 karat gold; and e-coated to protect your jewelry and keep it looking new for longer.
14K plated jewelry carries the same luster and appearance as real gold jewelry, but comes at a price that you will love. It’s important to note that gold plated jewelry is likely to oxidize when exposed to water, sweat, perfumes, lotions etc. These elements can make the gold plating wear off, exposing the base layer of metal—so remember to take off your jewelry before you go for a swim, shower or workout to keep it looking new for longer.
Sterling Silver
Sterling Silver, also known as s925, is a precious metal made with 92.5% silver and blended with other metals to make it stronger. Like all our jewelry, our sterling silver jewelry is nickel, lead, and cadmium free making it suitable for anyone with sensitive skin. Explore to see how this precious metal works in harmony with every La Costa design; our sterling silver jewelry is stylish, and safe for sensitive skin.
Vermeil
Vermeil (pronounced vehr-may) is where sterling silver and 14k gold plated come together and create magic. Vermeil jewelry is made with a sterling silver base material and plated in 14K gold that is 2.5 microns thick. A premium offering of our best selling styles, our vermeil jewelry is made with a solid s925 sterling silver base and plated in 14K gold that is 10x thicker than the industry standard 'plated gold'. Vermeil is a hypoallergenic material, made to last for years.
The thick plating gives it a luxe look, just like real gold. This premium product is hypoallergenic, made to last and is perfect if you have sensitive skin. It is a water and tarnish resistant material, but like all plated jewelry, it needs some TLC to keep it looking fresh.
14K Gold
14K Gold (i.e 14 parts pure gold and 10 parts alloy) has a rich tone and look that makes this a must-have material in your jewelry box. Our most premium offering, solid 14K gold jewelry, is the ideal mix of purity, durability, and value for your money. These are heirloom pieces that will last a lifetime, for you and the ones you love.
Cubic Zirconia
Cubic zirconia, also known as CZ, is a material similar to a diamond in its appearance, brilliance and crystal clarity, but it is a synthesized (i.e. man-made) crystalline material that is clear, hard, and flawless.
Just like real diamonds, Cubic Zirconia is also measured by the 4 Cs—Cut, Clarity, Color and Carat. All our jewelry has the highest grade (AAAAA) cubic zirconia. This means these stones are crafted and polished to perfection making them shine just like real diamonds, with no polish marks or grain lines.
Pearls
We use the highest quality of pearls in all our jewelry; freshwater and shell pearls. Shell pearls are made from the inner lining of oysters i.e. mother of pearl. This substance is ground down to a powder and coated on for a beautiful, lustrous finish that you will find across our earrings, necklaces and bracelet collections. Similarly freshwater pearls are real pearls that are harvested in lakes and are used in our most popular styles like our Freshwater Pearl Hoops, Freshwater Pearl Necklace and more.
Opals
Opals add the perfect touch of color to our 14K gold plated jewelry. Opals used in La Costa jewelry are synthetically made in laboratories and contain 80% silica, making it a high-quality, long lasting and a great addition to all all-gold jewelry stack.
Opal is a form of silica, chemically similar to quartz but containing water within the mineral structure. Precious opal generally contains between 6 – 10% water and consists of microscopic silica spheres arranged in a regular pattern.
