August has three recognized birthstones: peridot, spinel, and sardonyx. Peridot's vivid yellow-green is the month's best-known color, while spinel brings a wide palette and sardonyx offers distinctive bands of color. Together, they give August birthdays far more choice than a single green-stone look suggests.
This guide compares the three stones, explains their traditional symbolism, and shows how to choose an August birthday gift without making assumptions about a product's actual gem content.
Quick Answer: What Is the August Birthstone?
Peridot, spinel, and sardonyx are all recognized August birthstones. Peridot is the primary modern choice most shoppers associate with August; spinel and sardonyx are established alternatives.
Key Takeaways
- August has three birthstones: peridot, spinel, and sardonyx.
- Peridot is known for a naturally green-to-yellow-green palette.
- Spinel occurs in many colors, including red, pink, blue, and violet.
- Sardonyx is a banded material combining layers of sard and onyx.
- Birthstone-inspired jewelry should be labeled by its verified material, not assumed from color.
Why Does August Have Three Birthstones?
Birthstone calendars developed over time rather than appearing as one permanent ancient list. Sardonyx has a long connection with August, peridot became the month's best-known modern choice, and spinel was added to the modern US list in 2016.
The result is useful for shoppers: one month can support bright green, colorful, or graphic banded styles. The “right” choice is the one that fits the recipient and is accurately described.
August Birthstones Compared
| Stone | Signature look | Traditional associations | Best for |
|---|---|---|---|
| Peridot | Yellow-green to green | Light, renewal, prosperity | Shoppers who love fresh, bright color |
| Spinel | Broad range of colors | Hope, energy, restoration | Someone who wants flexibility beyond green |
| Sardonyx | Layered reddish-brown, white, or dark bands | Strength, courage, protection | Graphic, vintage, or signet-inspired style |
These meanings are cultural traditions, not promises of physical or emotional effects.
Peridot: August's Signature Green Stone
Peridot is the gem variety of the mineral olivine and is one of the few familiar gems strongly associated with a single color family. Its fresh green can range toward yellow-green, making it easy to recognize in August gift guides.
Choose peridot when the recipient already wears green, enjoys lively color, or wants an unmistakable August cue. Because color appearance varies with lighting and photography, review multiple product images before buying.
Spinel: August's Colorful Alternative
Spinel appears in many colors and was historically confused with other gemstones, especially ruby. Its broad palette makes it the most flexible August option for someone who does not wear green.
When shopping, do not assume every red or pink stone is spinel. The product description should identify the material. “Spinel-inspired color” and “spinel” are not interchangeable claims.
Sardonyx: August's Banded Classic
Sardonyx is recognized by contrasting layers or bands, traditionally combining sard's reddish-brown tones with onyx's lighter or darker layers. It has a long history in carved cameos, seals, and signet-style objects.
This is the most architectural August option. It suits someone who prefers pattern, warm neutrals, vintage references, or a stronger graphic look over sparkle.
How to Choose August Birthstone Jewelry
Choose by Color Preference
Peridot delivers the clearest green August signal. Spinel offers more freedom if the recipient wears pink, red, blue, or violet. Sardonyx works for neutral and warm-toned wardrobes.
Decide Whether You Need the Actual Gem
If gem identity matters, verify the exact stone in the product description. If the birthday connection is the priority, a green birthstone-inspired accent can carry the August story at a wider range of styles and prices.
Match the Jewelry Type to the Recipient
A necklace is generally easy to gift. A bracelet feels casual and stackable. A ring can be highly personal, but you need sizing unless the design is adjustable. Earrings work well when you already know the recipient wears pierced styles.
Check Care and Construction
Confirm the exact stone or accent, metal or finish, dimensions, closure, sizing, and care directions. Keep all durability, water-resistance, and skin-sensitivity claims product-specific.
August Birthstone Gift Ideas

| Vintage | Banded or signet-inspired form | Echoes sardonyx's graphic history |
| Color lover | Spinel in a verified favorite shade | Personalizes August beyond green |
