This is a variation of the handmade birthstone ring, with a sterling silver-filled swirl added around the stone. This ring is also perfect as a mother's ring, or maybe a perfect promise ring if you are on a budget. • Handmade & Personalized: Crafted in sterling silver-filled wire*, cubic zirconia or high-quality synthetic opal*, each ring is unique due to its craftsmanship. • Half-Sizes Available: Just add your choice in the personalization box or note to seller. (You will still have to pick a size in the options.) • Important: Specify the colors or birthstones in the personalization box according to our chart. I cannot make the ring without this information! • Birthstones: o January: Garnet o February: Amethyst o March: Aquamarine o April: White Topaz o May: Emerald o June: Alexandrite o July: Ruby o August: Peridot o September: Sapphire o October: Tourmaline or Opal o November: Yellow Topaz o December: Blue Topaz Pictured in garnet, aquamarine and alexandrite. *Lab-grown synthetic opals mimic natural opals but are more durable and resistant to temperature, humidity, and heat changes due to their lack of water content. *Sterling silver-filled wire has a durable thick outer layer of sterling silver bonded to a red brass alloy core. Unlike silver-plated wire, it maintains its appearance for years.
