Welcome to the most comprehensive Anime Last Stand tier list you’ll find anywhere! I’ve spent countless hours analyzing every unit…
The Smithing Event has introduced one of the most exciting additions to Grow a Garden – the Gem Egg. This prismatic-rarity egg features six gemstone-themed pets, including two ultra-rare Prismatic pets with drop rates under 1%. If you’re wondering which pets you can hatch from the Gem Egg and how to get your hands on this valuable egg, I’ve got you covered with everything you need to know.
The Gem Egg is a permanent addition to Grow a Garden that arrived with the Smithing Update. Unlike temporary event eggs, this beauty-crafted egg will remain available even after the Smithing Event ends. With its distinctive white and red gradient design adorned with green, blue, red, and purple crystals, the Gem Egg stands out as one of the most visually stunning eggs in the game.

| Total Pets | 6 gemstone-themed pets |
| Hatch Time | 4 hours 10 minutes |
| Ultra-Rare Pets | Ruby Squid (0.5%), Diamond Panther (0.5%) |

The Gem Egg contains six incredible gemstone-themed pets, each with unique abilities that can dramatically boost your farming efficiency. Here’s the complete breakdown of every pet you can hatch, along with their exact drop rates and abilities.
| Pet | Rarity | Drop Rate | Primary Ability |
|---|---|---|---|
| Topaz Snail | Common | 45% | Lucky Harvest bonus – 7.13% chance to grant Cleansing Pet Shard (max 50%) |
| Amethyst Beetle | Rare | 32% | Initiates beetle battles every 5.56 minutes, rewards items on victory |
| Emerald Snake | Legendary | 14% | 1.75% chance to duplicate shop purchases (seeds/gears/eggs), reduces nearby pet cooldowns by 5% |
| Sapphire Macaw | Mythical | 8.25% | 16.54% chance to apply Crystallized mutation every 7.53 minutes |
| Ruby Squid | Prismatic | 0.5% | Continuously copies random pet passive abilities |
| Diamond Panther | Prismatic | 0.5% | 4-8% chance to age up random pet when harvesting 12+ mutation fruits |
Topaz Snail – The Common Workhorse
The Topaz Snail might be common, but don’t underestimate its value. When you trigger a Lucky Harvest, this pet provides a 7.13% chance to grant you a Cleansing Pet Shard, capped at 50%. For players working on pet shard collection, this is an incredibly reliable helper that you’ll encounter frequently due to its 45% drop rate.
Amethyst Beetle – The Battle Master
This Rare pet brings entertainment and rewards to your garden. Every 5.56 minutes, the Amethyst Beetle initiates battles with other players’ beetles. When your beetle wins, you receive valuable rewards. The outcome depends on your beetle’s weight and level, making this pet both fun and profitable. It’s not just about farming – it’s about dominating the beetle battle arena.
Emerald Snake – The Efficiency Expert
With a 14% drop rate, the Emerald Snake is one of the most valuable pets in the Gem Egg. This Legendary serpent offers two incredible benefits. First, it provides a 1.75% chance to duplicate seeds, gears, or eggs when purchasing from shops, essentially giving you freebies over time. Second, all pets within a 10-stud radius have their trait cooldowns reduced by 5%, helping your entire pet team work more efficiently.
Sapphire Macaw – The Mutation Specialist
The Sapphire Macaw, with its 8.25% drop rate, is perfect for players chasing high-value mutations. Every 7.53 minutes, this Mythical bird has a 16.54% chance to mutate nearby fruits with the Crystallized mutation. If you’re focused on mutation farming for maximum profit, this macaw becomes an essential addition to your active pet roster.
Ruby Squid – The Ultimate Copycat
Here’s where things get insanely valuable. The Ruby Squid, with only a 0.5% drop rate, is one of the rarest pets in the entire game. Its ability is game-changing: it continuously copies random pet passive abilities from other pets in your garden without cooldown restrictions. This means you essentially get double the benefits from your best pets. Imagine having two growth-boosting pets active at once, or doubling your mutation application chances. The Ruby Squid is the pet that serious collectors and min-maxers dream about.
Diamond Panther – The Age Accelerator
Equally rare at 0.5%, the Diamond Panther offers a completely unique ability. When you harvest fruits with 12 or more mutations, there’s a 4-8% chance that a random pet in your garden will age up by one level. This is massive for progression, especially when you’re trying to reach those high-level pet milestones for slot upgrades. The Diamond Panther is the second pet in Grow a Garden capable of increasing another pet’s age, making it incredibly valuable for long-term farming strategies.
There are four proven methods to obtain Gem Eggs, each with different requirements and success rates. I’ve tested all of them extensively, and here’s exactly what works best.
This is the most reliable and cost-effective method for most players. Crafting Gem Eggs gives you complete control over how many eggs you produce, making it perfect for mass-hatching attempts at those ultra-rare pets.
Crafting Requirements:
Step-by-Step Crafting Process:
Pro Tip: The 10-minute crafting time means you can produce 6 Gem Eggs per hour if you maintain a constant crafting queue. This is your best path to hatching those 0.5% Prismatic pets.
Treasure Digging offers a chance-based method to obtain Gem Eggs along with other exclusive Smithing Event rewards.
How Treasure Digging Works:
Treasure Digging Strategy:
While the 5.43% drop rate might seem low, Treasure Digging provides value beyond just Gem Eggs. You’ll also receive Common Coal, Rare Coal, Legendary Coal, Divine Coal, and other event-exclusive items. If you’re actively playing during the Smithing Event, check your dig status every 50 minutes to maximize your free attempts.
The main downside is the random nature – you could get multiple Gem Eggs in quick succession or experience dry streaks. However, the passive regeneration means you’re always making progress toward rewards.
For players with substantial Sheckles, buying Gem Eggs directly from the Pet Egg Shop offers instant gratification.
Shopping Process:
Stock Management Tips:
The Pet Egg Shop refreshes its inventory every 30 minutes, but Prismatic-rarity eggs like the Gem Egg have low spawn rates in the rotation. Here’s how to never miss a restock:
Many players prefer this method for their first Gem Egg, then switch to crafting for bulk hatching attempts.
If you’re willing to invest real money, purchasing Gem Eggs with Robux is the fastest method and includes pity system benefits.
Robux Pricing:
| Package | Cost | Value Per Egg |
|---|---|---|
| 1 Gem Egg | 149 Robux | 149 Robux/egg |
| 3 Gem Eggs | 429 Robux | 143 Robux/egg |
| 10 Gem Eggs | 1,249 Robux | 124.9 Robux/egg |
Why Consider Robux Purchases?
The 10-pack offers the best value at approximately 16% savings compared to buying single eggs. However, for most players, crafting remains more economical if you can invest the time to farm Common Coal and Common Eggs.
With limited pet slots (especially at lower levels), choosing which Gem Egg pets to keep active is crucial. Here are my top recommendations based on hundreds of hours of testing different combinations.
Ruby Squid – The Ultimate Game-Changer
If you manage to hatch this 0.5% Prismatic pet, activate it immediately. The Ruby Squid’s ability to copy other pet passives without cooldown is potentially the single most valuable pet ability in Grow a Garden. Pair it with high-value pets like mutation applicators or growth boosters, and you’ve essentially doubled your farming efficiency. This pet alone can increase your Sheckle income by 30-50% when properly utilized with complementary pets.
Emerald Snake – The Free Money Generator
The Emerald Snake’s 1.75% duplication chance might not sound impressive, but over time it adds up significantly. Every time you buy seeds from the shop (which you’ll do constantly), there’s a chance to get a free duplicate. The 5% cooldown reduction for nearby pets is excellent as well. I’ve personally saved millions of Sheckles thanks to this snake’s duplication ability, making it worth every bit of the 14% hatch rate grind.
Diamond Panther – Long-Term Investment
For players focused on pet progression, the Diamond Panther is invaluable. The ability to passively age up pets while harvesting high-mutation fruits accelerates your path to pet slot upgrades significantly. Since unlocking additional pet slots requires trading in level 20-75 pets, having a Diamond Panther active means you’re always making progress toward expansion even during normal farming activities.
Sapphire Macaw – Mutation Farmers
If your farming strategy revolves around high-value mutation stacking, the Sapphire Macaw deserves an active slot. The Crystallized mutation provides excellent profit multipliers, and having a 16.54% application chance every 7.53 minutes significantly increases your mutation farming output.
Amethyst Beetle – Entertainment + Rewards
While not essential for pure profit optimization, the Amethyst Beetle offers a fun mini-game element with beetle battles while generating passive rewards. If you have spare pet slots and enjoy the battle mechanics, it’s a solid choice that adds variety to your gameplay.
Topaz Snail – Early Game Helper
The Topaz Snail shines when you’re actively working on Cleansing Pet Shard collection, but once you’ve met your shard goals, other pets generally provide more value. Consider it a solid early-game pet that you’ll eventually replace as your roster improves.
With both Prismatic pets at 0.5% drop rates, you’ll need serious dedication to hatch them. Here’s the math:
Optimal Crafting Schedule:
Beginner Setup (3-5 slots):
Mid-Game Setup (6-9 slots):
Endgame Setup (10-13 slots):
Mistake #1: Crafting Without Resource Stockpiles
Don’t start crafting Gem Eggs one at a time. The 10-minute crafting window means inefficient resource usage if you’re constantly waiting for more Coal. Stockpile at least 30 Common Coal and 10 Common Eggs before beginning your Gem Egg crafting session.
Mistake #2: Ignoring Pet Synergies
The Ruby Squid’s copying ability is wasted if you don’t have valuable pets for it to copy. Before activating your Ruby Squid, ensure you have high-impact pets like mutation applicators or growth boosters in your active roster.
Mistake #3: Selling Common Gem Egg Pets Too Quickly
Even though the Topaz Snail is common, it’s still useful for specific tasks. Don’t immediately sell every Common pet you hatch – evaluate whether it fills a gap in your current farming strategy first.
Mistake #4: Not Using Discord for Stock Alerts
Manually checking Raphael’s shop every 30 minutes is inefficient. Join the Stock Discord servers and enable Gem Egg notifications to never miss restock opportunities, especially if you’re supplementing crafting with shop purchases.
Mistake #5: Hatching Without Preparation
Gem Eggs take 4 hours and 10 minutes to hatch. Plan your hatching schedule around your play sessions to avoid wasting time with eggs sitting ready to collect while you’re offline.
How does the Gem Egg compare to previous event eggs like the Gourmet Egg, Jungle Egg, or Paradise Egg?
Advantages:
Disadvantages:
Overall, the Gem Egg represents one of the best long-term investments in Grow a Garden. The permanent availability means you can work toward those Prismatic pets at your own pace without event time pressure.
Since Common Coal is your primary bottleneck for Gem Egg crafting, optimize your coal generation:

Coal Generation Rate:
Common Eggs are required for Gem Egg crafting, so maintain a steady supply:
Each Gem Egg crafting costs 1,000,000 Sheckles. Here’s how to maintain steady income:
High-Efficiency Farming:
Passive Income:
The Smithing Event runs from November 15-22, 2025 (7 days). Here’s how to maximize your Gem Egg acquisition during this period:
Days 1-2: Resource Gathering Phase
Days 3-5: Mass Crafting Phase
Days 6-7: Final Push
Gem Eggs require 4 hours and 10 minutes to hatch naturally. You can speed this up by using pets with hatch time reduction abilities like Kiwis, Chickens, Roosters, Bald Eagles, or their special variants. Alternatively, spend Robux for instant hatching.
The Ruby Squid is objectively the best Gem Egg pet due to its game-changing ability to copy other pet passives without cooldown. However, at only 0.5% drop rate, it’s extremely rare. The Emerald Snake is the best readily-obtainable pet at 14% drop rate, offering valuable duplication chances and cooldown reduction.
Yes. Unlike temporary event eggs, the Gem Egg is a permanent addition to Grow a Garden. You can continue crafting Gem Eggs at the Pet Workbench, purchasing from Raphael’s shop, and buying with Robux even after November 22, 2025.
Statistically, you need approximately 200 Gem Egg hatches to have a 50% chance of obtaining each Prismatic pet. For a 90% chance of getting both, expect to hatch 400-500 Gem Eggs. This is why stockpiling resources and mass crafting is essential.
Currently, pets in Grow a Garden cannot be directly traded. However, you can gift pets to other players through the gifting system. The trading feature is expected to be added in future updates.
Nothing. Gem Eggs remain in your inventory permanently and can be hatched at any time. There’s no rush to hatch them during the Smithing Event specifically unless you want to benefit from any temporary event bonuses.
Yes, there are two methods to speed up crafting. First, certain furnace submissions grant random crafting time reductions (usually 10 seconds). Second, you can potentially skip ingredients using Robux, though this may not be cost-effective for Gem Eggs specifically.
For most players, hatch them immediately. You need to discover which pets you’re getting to plan your pet roster strategy. The only reason to save Gem Eggs is if you’re at maximum pet storage capacity and haven’t cleared space yet.
The pity system in Grow a Garden occasionally grants higher rarity pets after multiple egg purchases with Robux. While the exact mechanics aren’t publicly disclosed, purchasing 10-packs increases your chances of triggering pity compared to single purchases.
The fastest method is completing furnace submissions at the Blacksmith Smith NPC. Submit one fruit, one gear, and one pet to receive Common Coal rewards. Focus on submitting items you don’t need rather than valuable resources. You can complete submissions continuously during active play sessions.
The Gem Egg represents one of the most significant additions to Grow a Garden’s pet system. With six unique gemstone-themed pets ranging from the accessible Topaz Snail to the ultra-rare Ruby Squid and Diamond Panther, there’s something valuable for every player regardless of luck or investment level.
The permanent availability of Gem Eggs through crafting means you can work toward those coveted Prismatic pets at your own pace, making this a long-term goal worth pursuing even after the Smithing Event concludes.
Whether you’re a casual player hatching your first Topaz Snail or a dedicated collector chasing that 0.5% Ruby Squid, the Gem Egg system provides engaging progression that will keep you coming back to Grow a Garden for weeks or months to come. Save this guide and bookmark it for future reference as you continue your Gem Egg hatching journey!
