OSRS Sapphires vs Emeralds: Cutting for 99 Crafting — Profit & XP Guide

Game screenshots and facts are cited from the Old School RuneScape Wiki (strategy, equipment, drops, and related pages). Writing is original editorial, not a copy of the wiki article.

Training Crafting to 99 is a battle between speed, cost, and attention. Among the dozens of paths, cutting sapphires and emeralds remains one of the most popular because it is simple, uses a single tool, and can be done at a bank with minimal clicks. But the real question isn't whether to cut gems—it's which gem to cut and what to do with the cut result afterward.

This guide compares cutting sapphires against emeralds for 99 Crafting, using data from the official OSRS wiki. We'll cover XP rates, profit per gem, bulk buying, alternative uses like jewellery and bolt tips, and when buying gold or a leveling service is the honest shortcut to skip the grind.

Requirements & Starting Point

Before you start bulk cutting, you need two things: the right Crafting level and enough capital to buy uncut gems by the thousand. Sapphires require level 20 Crafting to cut, while emeralds unlock at level 27. Both use a chisel, which never breaks.

If you're starting a fresh account, quests like The Knight's Sword or Sheep Shearer can skip early levels, but for mass training you'll still want to reach at least 20 before touching sapphires. The wiki's pay-to-play Crafting training page lists leather items from 1–20 as the fastest early method, requiring about 215 leather and 43,000 coins.

Cutting Sapphires: The Level 20 Workhorse

Cutting an uncut sapphire grants 50 Crafting experience. That might not sound like much, but the simplicity is the appeal: click the chisel, click the gem, watch the XP drop. If you were to cut sapphires all the way from level 20 to 99, you would need 13,034,431 total XP, which translates to 260,689 uncut sapphires.

The profit from pure cutting depends entirely on the spread between uncut and cut sapphire prices on the Grand Exchange. The wiki's Sapphire page lists several products that turn cut sapphires into profit, but the cutting step itself can be a loss if uncut sapphires are overpriced. Always check current prices before committing to a bulk buy. Sapphires also have a GE buy limit, so accumulating 260k of them may take days or weeks of offers unless you buy from other players or multiple accounts.

One advantage of sapphires is their low barrier to entry: at level 20 you can start immediately, and the per-gem cost is usually lower than emeralds, making it easier to buy smaller batches. However, after level 27, emeralds give 35% more XP per gem, making them the better choice for pure XP unless sapphires are significantly cheaper per XP. NPC shops like Herquin's Gems in Falador, the Gem Trader in Al Kharid, and the Ardougne Gem Stall sell uncut sapphires at fixed prices, but their stock is tiny and restocks slowly, so they are only useful for small top-ups or ironmen.

Cutting Emeralds: The Higher-Level Upgrade

Emeralds require level 27 Crafting and give 67.5 XP per cut. If you start cutting emeralds at level 27 and never switch, you would need 193,103 uncut emeralds to reach 99 Crafting—about 67,586 fewer gems than the sapphire route. That means fewer bankstanding clicks and less time spent buying supplies.

Emeralds are typically more expensive per gem than sapphires, so the real decision is cost per XP. If an uncut emerald costs less than 1.35 times the price of an uncut sapphire (since 67.5 / 50 = 1.35), then emeralds are the better value for XP. Use that ratio when comparing live GE prices.

Beyond raw cutting, emeralds unlock profitable fletching (bolt tips) and jewellery crafts that often beat sapphires for profit, as we'll see below. Similar to sapphires, emeralds are sold by NPC shops like Herquin's Gems, the Gem Trader, and the Ardougne Gem Stall, but stock is limited to one or two per world with long restock timers.

The Real Money: Crafting Jewellery After Cutting

Cutting gems is just the first step. Both sapphires and emeralds can be crafted into jewellery at a furnace using a gold bar and the appropriate mould. This adds extra XP and can turn a break-even cutting operation into a profitable one. The table below shows selected jewellery from the wiki's Sapphire and Emerald pages, with costs and profits calculated assuming all inputs are bought from the Grand Exchange at the time of writing.

Notice that sapphire rings have the best Coins/XP among the basic rings, but emerald necklaces actually beat sapphire necklaces for profit per XP. Crafting jewellery adds bank runs and furnace time, so the XP/hr is lower than pure cutting, but the profit can fund more supplies. Many players use jewellery crafting as a semi-AFK money-making method while watching the market.

Fletching Bolt Tips: The Hidden XP Outlet

If you're also training Fletching, cut sapphires and emeralds can be used to make bolt tips. The wiki's Fletching tables show that sapphire bolt tips require level 56 Fletching and give 4 XP per gem, while emerald bolt tips require 58 Fletching and give 5.5 XP per gem. The profit picture is stark: sapphire bolt tips currently result in a loss of about 82 coins per gem, while emerald bolt tips turn a profit of about 153 coins per gem.

That means emeralds are the clear winner if you want to offload cut gems through Fletching, because you simultaneously make money and gain Fletching XP. Sapphire bolt tips are usually not worth it unless you need them for your own bolts and value the combined XP more than the loss.

Enchanting & High Alchemy: The Magic Layer

For accounts with Magic levels, enchanting cut gem jewellery adds another profit step. Using Lvl-1 Enchant (7 Magic) for sapphire jewellery and Lvl-2 Enchant (27 Magic) for emerald jewellery costs cosmic runes plus elemental runes, but the enchanted products often sell for far more. For example, a sapphire ring enchanted into a ring of recoil yields about 367 coins profit and 17.5 Magic XP per cast, working out to 20.97 Coins/XP—far better than almost any raw Crafting method. Emerald rings into rings of dueling give 156 coins profit and 37 Magic XP per cast, but only 4.22 Coins/XP because the emerald ring already costs more.

High Alchemy adds another layer if you have 55 Magic, but the wiki's combined tables assume a staff of fire and nature runes, and the profit after nature rune cost is often lower than selling on the GE. Magic-assisted processing can be excellent for ironmen or players who want Magic XP alongside Crafting, but it requires more attention and bank management.

Time and Cost Tradeoffs: Sapphires vs Emeralds for 99

Let's put the numbers side by side for the pure cutting route from their respective starting levels to 99 Crafting:

Emeralds reduce the number of cuts by about 26%, which directly translates to less time and fewer supplies. However, emeralds cost more per gem, so your total capital outlay could be similar or higher. The true hourly XP rate for cutting depends on how fast you can bank and cut; the wiki does not list a single universal rate because it varies with tick manipulation and inventory management. Players who use menu entry swapper or cut at a bank with a full inventory can push well above the standard rates, but you should verify current benchmarks on the wiki's training page.

Cost-wise, if uncut sapphires and emeralds are roughly equal in price per gem, emeralds are strictly better because they give more XP per coin. If sapphires are significantly cheaper—say, less than 74% of the emerald price—then sapphires may win on pure cost per XP. Use the ratio 50/67.5 ≈ 0.740 as your break-even multiplier.

Common Mistakes and How to Avoid Them

• Ignoring the buy limit: Both sapphires and emeralds have Grand Exchange buy limits. Trying to buy 200k at once will stall your offers for days. Plan ahead and buy in increments or use multiple accounts.
• Not checking cut vs uncut prices: Sometimes cut gems sell for less than uncut due to oversupply. Always compare before cutting.
• Using sapphires past level 27 without reason: After 27, emeralds give more XP per gem, so unless sapphires are massively cheaper per XP, you're wasting time.
• Forgetting alternative products: Cut sapphires can be made into sapphire lanterns for quests or silvthrill rods, but those are niche. Emeralds have consistent demand through rings of dueling and binding necklaces.
• Tying up too much capital: Buying 200k uncut gems at once can lock up hundreds of millions of gold. If the market dips, you may have to sell at a loss to free up cash.

Buying Gems in Bulk and the Honest Shortcut

Most bulk buying happens on the Grand Exchange, but NPC shops like Unferth's Green Gemstone Gems in Keldagrim sell uncut gems at fixed prices. The stock is tiny and restocks slowly, so it's not a source for mass training, but it can be useful for ironmen or for topping off a few hundred gems without waiting on GE offers.

For mains, the honest shortcut is simple: if you don't have the upfront gold to buy 200k uncut gems, you can either grind money-making methods for dozens of hours, or you can view live gold rates and buy gold to fund your supplies instantly. Doing so is allowed under Jagex's rules if you use a reputable marketplace, and it can save you weeks of preparation. Alternatively, some players buy a crafting service or account to skip the grind entirely, though that carries its own risks and should be approached with caution.

Practical Next Step: From 20 to 99

Here's a straightforward plan for a main account that wants to use sapphires and emeralds efficiently:

1. 1–20 Crafting: Craft leather items as described on the training page. This costs about 43k and takes less than 10 minutes.
2. 20–27 Crafting: Cut sapphires if you value early profit or want to start immediately. You only need about 5,902 XP for level 27, which is 119 sapphires.
3. 27–99 Crafting: Decide between sapphires and emeralds based on the cost per XP ratio. If emeralds are cheaper per XP, use emeralds; otherwise stick with sapphires. Consider processing cut gems into jewellery or bolt tips to recoup costs.
4. 54+ Crafting (optional): Switch to battlestaves or d'hide bodies if you want faster XP and have the capital. These methods often beat gem cutting for raw XP.
5. 83+ Crafting (optional): Amethyst cutting becomes available and can be very profitable, but requires high Mining or buying amethyst.

If you're short on time or gold, the most efficient play is often to buy the raw materials with purchased gold and then process them into finished goods to recover some of the cost. The market is always moving, so keep an eye on the wiki's live price pages and adjust your method accordingly.
