11 Overview
22  
33 Items in Starsand Island have a quality rating represented by stars. Higher-quality items sell for more at shops and produce better results when used as crafting or cooking ingredients. The quality system applies primarily to crops, animal products, and fish. Understanding how quality works and how to improve it is one of the best ways to increase your income.

55 Quality matters beyond sell price. Higher-star ingredients produce better dishes when used in cooking recipes, and NPCs react more favorably when gifted higher-quality items. Some Bulletin Board requests also specify a minimum quality tier, so a regular tomato will not satisfy a request that asks for a gold-star tomato.

77 Quality Tiers
88  
99 Every qualifying item in the game is assigned one of five quality tiers. The tier is shown as a star icon on the item tooltip in your inventory. Each tier applies a sell price multiplier on top of the item's base value.
1010  
1111 TierStar IconSell Price MultiplierNotesNormalNo star1.0x (base price)Default quality for all harvested and gathered itemsFine1 bronze star~1.1xSlight improvement; common with basic fertilizer useSuperior1 silver star~1.25xRequires consistent fertilizer application or high animal happinessPerfect1 gold star~1.5xGold-quality products sell for roughly 1.5x to 2x base valuePremium1 diamond star~2.0x+Highest tier; rare drops from max-happiness animals and cross-bred variants
1212 The exact multiplier varies slightly by item category. Crops, animal products, and fish each use the same tier names but the sell price bonus can differ. Gold-quality animal products, for example, can sell for 2 to 3 times the standard price depending on the specific product.
1313  
1414 Crop Quality
1515  
1616 Crops harvested from your farm have a star quality rating that affects their sell price. Higher-star crops sell for more and produce better cooking ingredients when processed at the Separator or used directly in recipes at the Campfire or Gas Stove.

1818 How to Increase Crop Quality
1919  
2020 The primary way to improve crop quality is through fertilizer. Fertilizers are purchased from Graminova at the Happiness Seed Shop and applied to tilled soil before or after planting.

2323 Yield Fertilizer increases the number of items harvested per crop, while Ripening Fertilizer shortens the growth cycle. Gmax Fertilizer III is specifically for Gmax crops (Pineapple, Watermelon, Pumpkin, Winter Melon planted in 3x3 plots) and increases the chance of a mutation into the giant Gmax variant.
2424  
2525 Workpedia Farming Skills
2626  
2727 Your Workpedia contains farming skills that can be upgraded using Starsand Points. Several of these skills directly or indirectly affect crop quality and yield. Unlock higher-tier skills by completing Graminova's certification quests.

3030 The Bountiful Harvest skill is particularly valuable for quality optimization because doubling your yield effectively doubles your chances of getting high-star items. Combined with Fertility Up (which lets you stack multiple fertilizer types on one plot), you can push both quantity and quality simultaneously.

3232 Other Crop Quality Factors
3333  
3434 SeedDetailsWatering consistencyWater your crops daily. Missed watering days do not reduce quality directly, but they delay growth, which means fewer harvests per season.Cross-breedingSome crops can be cross-bred to produce color variants. While color variants are primarily cosmetic and decorative, rare colors tend to sell for higher prices.Immortal SeedsCrops grown from Immortal Seeds (obtained via the Eternal Blessing Workpedia skill) regrow after harvest without replanting. Over multiple harvests, these crops can accumulate higher base quality.
3535 Animal Product Quality
3636  
3737 Animals on your ranch produce products at different quality levels. The key factor is animal happiness. Animals need at least 150 Happiness Points for a chance to produce premium-tier products.
3838  
3939 How to Increase Animal Happiness
4040  
4141 FeedDetailsFeed qualityUse Mirth Feed instead of standard feed. Mirth Feed is the most direct way to boost happiness and push products into higher quality tiers.Daily pettingInteract with each animal once per day by petting them.Clean enclosuresKeep animal enclosures free of debris and waste.ShelterProvide a roof or barn structure so animals can stay dry during rain.
4242 Standard vs. Premium Products
4343  
4444 Premium animal products sell for significantly more than standard versions. Gold-quality products can sell for 2 to 3 times the standard price.

4747 Rare animal variants (obtained through breeding) tend to produce higher-quality products than common variants. Breeding specifically for premium-product traits is one of the most effective long-term income strategies.
4848  
4949 Animal Byproducts
5050  
5151 Animals also produce byproducts with distinct quality variants. Golden Poop and Silver Poop are quality-variant byproducts that can be sold for high prices, especially at the Merchant Ship.
5252  
5353 Fish Quality
5454  
5555 Fish in Starsand Island have size variants that function similarly to quality tiers. The most notable is the King size, which is a significantly larger and more valuable version of a species. King-size fish are rare catches that appear in the same locations as their regular counterparts.

6060 Processing and Sell Price Multipliers
6161  
6262 Beyond raw quality, you can significantly increase item value by processing raw materials before selling. Each processing method applies a multiplier to the base sell price. Combining high quality with the right processing station is the key to maximizing profit.

6565 The Pickling Jar offers the highest processing multiplier for vegetables (up to 2.78x), while the Merchant Ship doubles the sell price of any item it accepts. Combining high-quality items with processing and selling to the Merchant Ship is the most profitable approach in the game.

6767 Quality Impact on Cooking and Gifting
6868  
6969 Quality is not just about sell price. It affects two other important systems:
7070  
7171 Cooking
7272  
7373 Using higher-star ingredients in cooking recipes produces dishes with better stats and higher sell values. A dish cooked with all gold-star ingredients will be worth noticeably more than one made with normal-quality items. The quality of the output dish is influenced by the average quality of the input ingredients.
7474  
7575 Gifting
7676  
7777 When giving gifts to NPCs, the quality of the item can influence how much affection you gain. A gold-star favorite gift will provide more affection points than a normal-quality version of the same item. This makes quality relevant for the relationship system as well.
7878  
7979 Maximizing Quality and Profit
8080  
8181 The following table summarizes the best strategies for each item category:
8282

8484 Tips
8585  
8686 Save your best gold-star and diamond-star items for the Merchant Ship. The 2x multiplier on top of an already high-quality item produces the biggest payouts in the game.Process crops before selling even if they are normal quality. A 10% bonus from the Separator adds up quickly over a full season of harvests.Invest in Workpedia farming skills early. Bountiful Harvest and Eternal Blessing pay for themselves many times over through increased yields.Check Bulletin Board requests carefully. Some requests require specific quality tiers, and fulfilling those requests often pays a significant bonus over the standard sell price.Combine Fertility Up (which allows stacking fertilizers) with Yield Fertilizer and Ripening Fertilizer on the same plot for maximum output per harvest cycle.For animal products, the difference between standard and premium is massive. Prioritize reaching 150 Happiness on your highest-value animals first.Pickling vegetables is almost always more profitable than selling them raw, even at normal quality. The 1.85x to 2.78x multiplier from the Pickling Jar is the highest passive processing multiplier available.King-size fish are rare but extremely valuable. If you catch one, consider selling it directly rather than processing it, unless you need it for a specific recipe.
