The Birthstone Pewter Ship Wheel will make your Heirloom Hourglass even more personal and unique for your special event or gift giving occasion. This custom closure is made using the finest solid pewter that is perfectly antiqued and sealed to prevent tarnishing. The gemstone of your choice is centered and embedded in the wheel, making it a very meaningful customization for Birthdays, Anniversaries, Weddings, and more. We offer 19 gemstones that you can select from on the drop down menu, and they cover all signs of the Zodiac, traditional and modern Anniversary gifts, many Wedding dress colors, and match many flower colors. These are beautiful synthetic gemstones that are all round cut and measure a full centimeter in diameter. Picture shown is the Emerald. For Weddings, Anniversaries, and Vow Renewals, select a wheel with the Bride’s birthstone in one side and the Groom’s in the other. For Valentine’s Day, select an engraved heart for one side, and your sweetheart’s birthstone for the other. The options for Birthdays, Mother’s Day, Fathers, Day, Grandparents Day, Baby Shower gifts, and more are limited only by your imagination and creativity! Hourglass must also be ordered.
