December Birthstone Jewelry
December is the rare month with more than one stone to choose from, and we work with three of them: turquoise, tanzanite, and sky blue topaz. Every piece here is built around a raw, uncut stone chosen by hand in our Atlanta studio, so no two are alike. Rings and studs sit in the $40 to $80 range.
Choosing a December birthstone
Turquoise is the December stone most people picture: opaque, sky to robin's egg blue, often threaded with brown or black matrix from the rock it grew in. In raw form it reads soft and earthy rather than glassy, and those matrix lines are character, not a flaw. Tanzanite is the opposite mood. Rough tanzanite is translucent and shifts between violet and blue depending on the light, so it looks deeper and dressier next to turquoise. Sky blue topaz sits in between, clear and pale, with crisp natural angles where the crystal broke.
A cut stone is ground to a uniform shape. We leave ours rough, set in 24k gold over electroformed copper, so the surface keeps its own geometry and the color varies piece to piece. If you want color you notice across a room, choose turquoise. For something quieter with depth, choose tanzanite. For a light everyday stone, choose blue topaz. Chains are 14k gold-filled (1/20) with a 24k dip.

What to expect from your December Birthstone Jewelry
Stones, metals, delivery windows, sizing and daily wear, gathered in one place.
Why is every raw stone different?
Each stone is a genuine raw gemstone, kept in the shape it grew in rather than cut and faceted. Colour, shape and inclusions shift from one crystal to the next, so no two pieces are identical and the one that arrives is a close relative of the photo rather than a copy. Every gemstone we set is conflict-free.
What are these pieces made of?
Gold styles are 14k gold-filled (1/20) finished with a 24k gold dip, warm pink styles use rose gold fill, and any style listing a silver option is made in 925 sterling silver. Gold fill is a thick bonded layer of gold rather than a thin plating, which is why it stands up to daily wear. We use recycled precious metals wherever possible, and every piece is 100% hand crafted in our Atlanta studio by Bailey.
When will my order reach me?
Shipping inside the US is free on every order with no minimum, and each parcel travels with tracking. In-stock pieces ship within 1 business day and land in 3 to 5 days, while made-to-order pieces are handcrafted within 10 to 15 business days before they ship. International orders travel at USPS rates, and any duties are the responsibility of the buyer.
What if I need to send something back?
Unworn pieces can come back to us within 100 days of delivery, with custom and made-to-order work as the two exceptions. Return postage is paid by the buyer unless the mistake was ours. Write to support@ringcrush.com and we will walk through it with you.
How do I land on the right ring size?
Sizes are listed on each ring page, and ready-to-ship rings are made in whole sizes. Every ring page carries a size guide plus a printable paper sizer you can measure with at home. If you sit between two sizes, take the larger of the two.
How do I keep a piece looking its best?
Keep it clear of chlorine, harsh cleansers and household chemicals, and slip it off before you swim. A soft dry cloth is all it takes to buff the metal back up. Store it dry and out of direct sun, and the Ringcrush gift box that comes with every order at no extra charge is a good place for it.
