Grandma Birthstone Necklace: How to Choose the Stones
Chic and Bling 9 min readWhose stones go on a grandma birthstone necklace?
Most families put the grandchildren on it, one stone each. That is the classic version, and it works because grandkids are the thing grandmas talk about most. Ask her friends. They have seen the photos.
But it is not the only way to do it. A few other approaches we see people choose:
- Grandkids only. One stone per grandchild, oldest to youngest. Simple and easy to explain when someone at church or the grocery store asks about it.
- Her children plus grandchildren. Good for small families, but it gets crowded fast. If the total is more than six or seven, a single piece can look busy.
- Her own stone, front and center. Some grandmas would rather wear something that is about them for once. A necklace in her own birth month, given "from all of us," says a lot.
- The newest arrival. A first grandchild or a new baby this year is a natural reason for a single-stone piece. You can add more later.
Our honest take: if you are not sure, go with the grandkids in birth order. It is the version she is least likely to need explained, and it is the one people comment on.
Birthstone chart by month
Here is the modern list as the American Gem Society and GIA publish it today [1][2]. Several months have more than one stone, which helps when you want a certain color.

A bit of history makes a nice line for the gift card. The modern American list was set in 1912, when the National Association of Jewelers met to standardize it. Later updates added stones such as tanzanite for December in 2002 and spinel for August in 2016 [3]. So if grandma remembers a different stone for her month, she is not wrong. The list has changed in her lifetime.
One more practical note. Gift-level birthstone jewelry usually uses colored crystals, zircon or lab-made stones in the month's shade rather than mined gems. That is normal and nothing to hide, and US guidelines say sellers should describe imitation and lab-made stones plainly [4]. Read the listing so you know what you are giving. Our own product pages state the material for each piece.

What if two grandkids share a month?
It happens all the time, and you have two good options.
Use one stone for both. On a single-stone or small necklace, one stone can stand for every grandchild born that month. Tell her in the card: "The blue one is for Mia and Jack." That small note is what turns a pretty necklace into the one she reaches for.
Use the alternate stone. Months like June, October and December have more than one official stone [1]. Two June grandkids can be pearl and moonstone. Two October kids can be pink tourmaline and opal. Same month, different look, and each child still has their own.
What we would avoid: repeating the identical stone side by side on a multi-stone piece. From across a room, it just looks like a mistake.
The stones matter less than the note that explains them. Write down whose stone is whose. She will keep that card.
One stone or many: which suits her?
Here is something worth knowing before you shop. Many grandma birthstone pieces, including ours, are single-stone designs. You pick one month per piece. That sounds limiting, but it often works better than a crowded pendant.
The "add one each year" idea is our favorite for big families. Start this Christmas with one piece, then give a ring or a bracelet in the next grandchild's stone at her birthday. She ends up with a set that grew with the family, and every piece has its own moment.
Think about how she dresses too. If she wears high necklines or reading glasses on a chain, a short pendant can get lost. A ring or bracelet in the same stone may get more wear.
When to order a grandma birthstone necklace for Christmas
Earlier than you think. In its 2025 holiday survey, the National Retail Federation found that 42% of shoppers planned to start browsing and buying before November, and the average shopper expected to spend $627.93 on gifts for family and friends [5]. Personal gifts like this one take a little planning, since you need everyone's birth months first.
A simple plan that works:
- Now: text the family group chat and collect birth months. Someone always forgets their own kid's month. That is fine.
- Next: decide the approach from the table above, then pick the metal color she already wears.
- By early December: place the order so you are not paying for rush shipping or settling for something else.
- Before wrapping: write the card that says whose stone is whose.
