pantsyfancy@Nareshbhardwaj Thank you so much for your interest in my work. The pendant is available in 18k gold plated, as well as 14k rose gold, 14k white gold, and 18k gold. On the right side of the product, there should be a list of available materials in the form of small squares showing the materials. Hover your mouse cursor over the squares for a description of the materials, and click on the one that you are interested in. Shapeways will list a price for the pendant in the selected material, and you can click the "Buy Now" button to purchase the pendant in that material.
Please let me know if it doesn't work or if you have questions about anything else.
