You've probably heard of birthstones. Maybe you own a piece of jewelry with your month's gem, or you're thinking of buying one as a gift. But there's a lot more to these stones than a simple color-coded calendar. This guide cuts through the fluff. We'll look at the official modern list, the traditional alternatives, what these stones actually mean (beyond the generic "love" and "prosperity"), and crucially, how to pick one you'll love wearing for years, not just because a chart told you to.

The Modern Birthstone List: Your Month-by-Month Breakdown
First things first. The list most jewelers use today was standardized in 1912 by the Jewelers of America and has seen a few updates. It's a mix of ancient tradition and modern gemology. Some months have just one stone, others have two or three. Here’s the complete rundown, with details you can actually use.
| Month | Modern Birthstone(s) | Color | Key Meanings & Notes | Hardness (Mohs) | Approx. Price Range* |
|---|---|---|---|---|---|
| January | Garnet | Deep Red (most common) | Protection, friendship. Surprisingly comes in greens and oranges too. | 6.5-7.5 | $-$$ |
| February | Amethyst | Violet to Purple | Calmness, clarity. Once as valuable as ruby, now affordable and abundant. | 7 | $ |
| March | Aquamarine, Bloodstone | Pale Blue, Green with red spots | Serenity, courage. Aquamarine's color is often enhanced by heat treatment. | 7.5-8, 6.5-7 | $$-$$$ |
| April | Diamond | Colorless (or fancy colors) | Strength, eternal love. Lab-grown diamonds are chemically identical and a major market shift. | 10 | $$$$ |
| May | Emerald | Rich Green | Rebirth, wisdom. Almost always has visible inclusions (“jardin”); a flawless emerald is extremely rare. | 7.5-8 | |
| June | Pearl, Alexandrite, Moonstone | White, Color-change, Sheeny | Purity, luck, intuition. Alexandrite (green to red) is incredibly rare & expensive. Cultured pearls are standard. | 2.5-4.5, 8.5, 6-6.5 | $$-$$$$ |
| July | Ruby | Vivid Red | Passion, vitality. The most important factor is color. Heat treatment is common and accepted. | 9 | $$$$ |
| August | Peridot, Spinel, Sardonyx | Lime Green, Various, Banded | Strength, healing. Spinel is a fantastic underrated gem, often mistaken for ruby or sapphire. | 6.5-7, 8, 6.5-7 | $-$$$ |
| September | Sapphire | Blue (but all colors except red) | Wisdom, loyalty. “Fancy” sapphires in pink, yellow, or padparadscha (orange-pink) are stunning alternatives. | 9 | $$-$$$$ |
| October | Opal, Tourmaline | Play-of-color, All colors | Creativity, hope. Opal is delicate and can crack if dried out. Tourmaline offers every hue imaginable. | 5.5-6.5, 7-7.5 | $-$$$ |
| November | Topaz, Citrine | Blue, Yellow to Orange | Friendship, strength. Most blue topaz is colorless stone irradiated to blue. Natural citrine is often paler. | 8, 7 | $ |
| December | Tanzanite, Turquoise, Zircon | Blue-Violet, Sky Blue, Various | Transformation, friendship. Tanzanite is found only in Tanzania. Blue Zircon has exceptional brilliance. | 6.5, 5-6, 6.5-7.5 | $$-$$$ |
* $ = Budget-friendly, $$ = Mid-range, $$$ = Premium, $$$$ = Luxury. Prices vary massively based on size, quality, and treatment.
See that hardness column? It's critical. A stone with a hardness below 7 (like opal, pearl, or turquoise) isn't ideal for a daily-wear ring. It'll scratch. Save those for earrings or pendants.
How to Choose the Right Birthstone for You (or a Gift)
Picking a birthstone isn't just about matching a month. It's about matching a person. Let's walk through the decision process.
Consider the Wearer's Lifestyle
An active nurse who uses her hands constantly needs a different stone than someone who wears jewelry only on special occasions. For rings and bracelets that take a beating, prioritize hardness (7+ on the Mohs scale). Sapphire, ruby, diamond, and even harder varieties of quartz are workhorses. Delicate stones like emerald, opal, or tanzanite are safer in protected settings like pendants or earrings.
I made this mistake early on. I bought a beautiful opal ring as a birthday gift. It was worn daily, and within a year, it had a small crack from an accidental knock. Lesson learned.
Look Beyond the Primary Color
Don't like the classic red of garnet? Good news—garnet also comes in vibrant greens (tsavorite), oranges (spessartite), and even color-changing varieties. Not a fan of pale blue aquamarine? Maybe the deep blue of a sapphire or the rich green of an emerald speaks to you more, regardless of your birth month. The modern list is a starting point, not a prison.
Budget and Value Perception
Be realistic. A natural, high-quality ruby or emerald will cost thousands. But you have options. Lab-created versions of ruby, sapphire, and emerald offer the same beauty and durability at a fraction of the price. For April, a lab-grown diamond is a legitimate and increasingly popular choice. For June, a cultured pearl or moonstone can be breathtaking without the Alexandrite price tag.
Birthstone Care & Durability: What No One Tells You
Jewelers often sell the romance, not the maintenance manual. Here's the unvarnished truth on keeping your birthstone looking its best.
Soft Stones (Mohs This includes Opal, Pearl, Turquoise, and Moonstone. They are porous or prone to chipping. Never clean them in ultrasonic cleaners. Avoid chemicals, perfumes, and lotions. Opals can craze if they get too dry—occasionally wipe them with a damp cloth. Store pearls separately to prevent scratches.
Heat & Light Sensitivity. Some stones fade. Amethyst and rose quartz can lose color in strong sunlight over years. Many treated stones, like irradiated blue topaz, are stable, but it's best to avoid extreme heat. When in doubt, keep them cool and shaded.
The Universal Cleaner? Mild dish soap, lukewarm water, and a soft brush (like a baby toothbrush). This works for 95% of gemstones. Rinse thoroughly and dry with a soft, lint-free cloth. Exceptions: pearls, opals, turquoise (damp cloth wipe only), and any stone with fractures that might trap water.
Think of it this way: your gemstone is a piece of the earth. It has strengths and vulnerabilities. Knowing them lets you enjoy it for a lifetime.
Your Birthstone Questions, Answered
Common Questions About Birthstones
How do I choose a birthstone for someone born in a month with multiple stones?
Look at the person's style and lifestyle. Garnet (January) is classic and durable, great for everyday wear. Alexandrite (June) is rare and color-changing, ideal for a statement piece. For December, Tanzanite offers unique blue-violet hues, while Turquoise and Zircon provide more traditional looks. Consider their wardrobe colors and how often they'll wear the jewelry. When in doubt, you can't go wrong with the first stone listed—it's usually the most popular and accessible.
Can my birthstone change?
The modern list from the Jewelers of America is the most widely accepted standard today. However, some people enjoy exploring older, traditional lists or cultural alternatives. There's no rule saying you must stick to your month's stone. Many choose a stone based on its meaning or a color they love. Your connection to the gem is more important than a calendar. I know several Aprils who wear morganite instead of diamond simply because they prefer the soft pink.
Are synthetic or lab-created birthstones a good choice?
Absolutely, and often a smarter one for jewelry. Lab-created gems like sapphire, emerald, or ruby have the identical chemical, physical, and optical properties as their mined counterparts. They are significantly more affordable, allowing for larger or higher-quality stones. They are also more ethical and environmentally friendly, as they require no mining. For engagement rings or daily-wear pieces, lab stones offer brilliance and durability without the high cost. The stigma is fading fast.
At the end of the day, a birthstone is a personal anchor. It can connect you to your birth month, a loved one, or simply a color and meaning that resonates. Use this guide not as a strict rulebook, but as a map to help you find a gem that you'll genuinely cherish. Whether it's a mined heirloom sapphire or a lab-created emerald for everyday sparkle, the best birthstone is the one that brings you joy every time you see it.
