Birthstone Gifts for Your Sister
Birthstone Gifts for Your Sister
The best birthstone gifts for a sister are pieces she can wear without thinking about them: a small heart necklace or pair of studs in her birth month's stone, a stacking ring that sits next to one in your stone, or a keepsake made for sisters, like a locket or a break-apart charm. Start with her birth month, then choose the piece by how she already wears jewelry.
Below you will find the twelve birth months with their stones, six kinds of gift with real pieces and prices, a quick way to match the gift to the sister, and a few care notes. If you are not sure of her stone, our month-by-month birthstone finder has all twelve months in one place.

Start with her birth month
A birthstone gift only works if the stone is right, so check the month before anything else. Some months have more than one stone, which gives you a choice of color and price.
| Birth month | Birthstone | Color |
|---|---|---|
| January | Garnet | Deep red |
| February | Amethyst | Purple |
| March | Aquamarine | Pale to light blue |
| April | Diamond | Colorless |
| May | Emerald | Green |
| June | Pearl, alexandrite or moonstone | White, color-change, milky white |
| July | Ruby | Red |
| August | Peridot or spinel | Yellow-green; many spinel colors |
| September | Sapphire | Blue |
| October | Opal or tourmaline | Play-of-color; pink, green and more |
| November | Topaz or citrine | Golden yellow to orange |
| December | Blue topaz, tanzanite or turquoise | Blue, violet-blue, sky blue |
For the months with two or three stones, you can pick the one that suits her taste or your budget. Our guides to the October, November and December birthstones explain those choices in detail.
Pieces made for sisters
Some gifts say sister without needing a birthstone at all. These two work well for a younger sister, or for a pair of sisters who would each like something to keep.
The locket is 925 sterling silver with rhodium plating and one natural diamond at the front. It opens to hold a tiny photo and measures 12.52 mm wide and 11.75 mm long, 17.7 mm overall. The listing notes it is light and sized for younger wearers, which makes it a good first locket for a little sister. The break-apart charm is 10K yellow gold, cast as two pieces: one reads Big Sister and the other Little Sister. Each half goes on its own chain, so the two of you wear one each. It measures 15.34 mm wide and 20 mm long.
If you have a few sisters, or want something for your mother and sisters together, our guide to birthstone jewelry gifts covers multi-stone pieces.
A birthstone heart necklace
A necklace is the easiest birthstone gift to get right. There is no ring size to guess, and a pendant sits away from knocks, so softer stones are fine there too. A heart reads as a gift between family without being too sweet.
From the Birthstone Company collection
Birthstone heart necklaces in 14K gold
All three are 14K yellow gold with a polished finish, each with a 3mm birthstone heart on a rope chain that closes with a spring ring clasp. The garnet is the January stone, aquamarine is March, and peridot is August. The aquamarine listing notes the stone is heat-treated, which is common for aquamarine. The same style comes in other months in our birthstone necklaces.
One idea we like: buy two of the same style, one in her stone and one in yours. Each of you wears your own month, and the matching chain and heart make it clear they belong together.
Birthstone earrings she will wear every day
Studs are the safest gift for a sister whose style you only half know. They go with everything, and a small stone in her color still feels personal.
From the Birthstone Company collection
Birthstone stud earrings
Sterling Silver 3mm Garnet Stud Earrings with Rhodium Plating January Birthstone
$21.21
View Piece →
The garnet pair is sterling silver with rhodium plating, each 3 mm natural garnet in a four-prong setting with push backs, and it is the least expensive piece in this guide at $21.21. The aquamarine hearts are also rhodium-plated sterling silver, 4.5 mm wide, in three prongs, and the listing notes the aquamarine is heat-treated. For a bigger birthday, the amethyst pair is 14K yellow gold with 5 mm round amethysts, also heat-treated. Browse more months in our stud earrings.
Stacking rings: her stone and yours
Thin birthstone bands are made to be worn together. Give her a ring in her stone and keep one in yours, or give her both so she wears the two months on one finger.
Both rings are sterling silver with rhodium plating, with the stone held in a bezel, a rim of metal that wraps its edge. The garnet ring measures 3.5 mm wide and the pink tourmaline ring 2.25 mm. Pink tourmaline is one of the two October stones. Both come in sizes 5 through 10.
Rings are the one gift where size matters. If you can, borrow a ring she wears on the same finger and have it measured. If that is not possible, choose a necklace or earrings instead. Our guide on how to choose a birthstone ring compares bands and settings.
A birthstone bracelet with more color
A bracelet carries more stones than a stud or a pendant, so it suits a sister who likes color. It is also a good choice when she already has a birthstone necklace from you.
This bracelet sets nine natural garnets along a paperclip chain of 925 sterling silver with gold-tone and silver-tone flash plating. The stones sit in open-back settings, so light reaches them from behind. It is 5.13 mm wide and 7.5 inches long, and fastens with a lobster clasp. More January pieces are in our January birthstone collection, and other months are in birthstone bracelets.
An initial necklace when you are unsure of her month
Not every sister cares about birthstones, and sisters-in-law are easy to get wrong on dates. An initial necklace is personal in a different way: it carries her name.
This necklace is 925 sterling silver with a polished finish and an initial R set with natural diamonds. It hangs on an extending chain with a spring ring clasp. The same style is made in other letters, and our initial necklaces collection has more shapes in gold and silver.
Matching the gift to your sister
| If your sister... | Consider | Why |
|---|---|---|
| Is younger, or still a child | The sister locket or a heart necklace | Light pieces, and the locket is sized for younger wearers |
| Is the big or little sister of a pair | The break-apart charm | Each sister keeps one half |
| Wears jewelry every day | Birthstone studs | Small and easy to pair with what she owns |
| Stacks rings | A stackable ring in her stone, plus one in yours | The two months sit side by side |
| Likes color | A birthstone bracelet | More stones than a stud or pendant |
| Is a sister-in-law, or you are unsure of her month | An initial necklace | Personal without needing a birth date |
Budget follows the metal more than the stone. In this guide, the sterling silver pieces run from $21.21 to $192.60, and the 14K gold pieces from $119.56 to $135.52, with the 10K gold break-apart charm at $205.36. For gifts timed to the holidays, see our birthstone Christmas gift guide.
Caring for her birthstone
Most of the stones in this guide wear well. Garnet rates 6.5 to 7.5 on the Mohs scale, peridot 6.5 to 7, amethyst 7, tourmaline 7 to 7.5 and aquamarine 7.5 to 8. That is fine for earrings, pendants and bracelets, and for rings that come off for chores and the gym.
- Clean with lukewarm water, a drop of mild soap and a soft brush, then dry with a soft cloth.
- Put jewelry on after lotion, perfume and hairspray.
- Store each piece in its own pouch so harder stones do not scratch softer ones.
- Wipe rhodium-plated and flash-plated silver gently, since harsh polishes can wear plating down.
Our jewelry basics guide covers metal care in more detail.
Sister birthstone gift questions
What is a good birthstone gift for a sister?
A birthstone necklace or a pair of birthstone studs in her month's stone is the easiest choice, since neither needs a size. For something made for sisters, a sister locket or a big sister/little sister break-apart charm works well.
Should I give her birthstone or mine?
Her own birthstone is the usual choice. To make it about the two of you, give a piece with both stones, or matching pieces in each of your months, such as two stacking rings or two heart necklaces.
What if I do not know my sister's birth month?
Choose a piece that does not depend on it, such as an initial necklace or a sister keepsake. If you know her birthday, our month-by-month finder gives the stone.
Which months have more than one birthstone?
June (pearl, alexandrite, moonstone), August (peridot, spinel), October (opal, tourmaline), November (topaz, citrine) and December (blue topaz, tanzanite, turquoise) all have more than one.
Is a birthstone ring a good gift if I do not know her size?
It is risky. Borrow a ring she wears on the same finger to check the size, or choose a necklace, earrings or a bracelet instead.
What does a break-apart charm mean?
It is one design cast as two halves, here reading Big Sister and Little Sister. Each half hangs on its own chain, so each sister wears one, and together they make the whole piece.
