Stiletto Knife | Urban Masked is a knife available as a rare special item from the Horizon Case and the Danger Zone Case; on LIS-SKINS, it currently runs roughly $140 to $180 depending on wear. But one pattern out of the thousand possible indexes trades for far more: pattern #402 strips away almost all of the gray stencil work, leaving the blade looking close to pure white — that's the one collectors call the White Gem. Below: what makes this pattern different, which indexes count as a cheaper alternative, and how to confirm a listing is actually the real thing before you pay for it.
What Urban Masked Is and Why It Has "Gems"
Urban Masked is a gray-and-white paint job sprayed through a masking-tape stencil: on most copies, a noticeable chunk of the blade stays covered in gray, with white showing through only in patches. The pattern index — a number from 0 to 999 fixed at the item's creation — decides exactly how that stencil lands. On the vast majority of indexes there's plenty of gray left; only on a handful does the gray shrink down to almost nothing, leaving the visible side of the blade close to solid white. It's the same logic as Blue Gem on Case Hardened: the same skin, but the specific pattern index decides whether a listing prices like an ordinary copy or several times more. White Gem is an unofficial community term, and similar mostly-white Urban Masked patterns are documented for more than just the Stiletto. Current community guides also identify White Gem patterns for the Skeleton Knife, Classic Knife, Flip Knife, M9 Bayonet, and Karambit. The specific "best" index differs per model, since the same texture lands differently on each blade's geometry.
Pattern #402: The Community's Top White Gem
Pattern #402 on the Stiletto Knife | Urban Masked is the index where the gray stencil is barely visible on the front side of the blade at all — it reads as one even sheet of white. Among the patterns the community has studied, #402 is considered the only fully white version of the Stiletto Urban Masked with no visible gray on the front side of the blade — one guide whose author manually reviewed all 1,000 indexes ranks #402 alone in Tier 1. That's why #402 specifically is what collectors mean by "Stiletto White Gem." Float on the Stiletto | Urban Masked ranges from 0.06 to 0.80, so it shows up in all five wears. The pattern index decides whether a copy counts as a White Gem, while float decides how worn it looks and can also affect appearance and price.
Alternative White Patterns: #718, #820, and Others
Besides #402, other Stiletto Urban Masked patterns carry an above-average share of white. In one of the more detailed community guides, #718 and #820 rank as Tier 2, while #37, #52, #161, #220, #372, and #509 sit in Tier 3. They keep more gray elements, so they don't count as a true match for #402, but they can be a more affordable alternative for a similar white look. This classification comes from the community, not Valve, so check the specific pattern visually before buying.
Getting a Stiletto Knife Urban Masked
The usual way to get a Stiletto Knife | Urban Masked is opening the Horizon Case or the Danger Zone Case. In both containers, the Stiletto sits in the rare special item pool (the "gold" drop) alongside the Navaja Knife, Talon Knife, and Ursus Knife — the odds of pulling one of those items run about 0.26% per case, and the specific knife, skin, and pattern index within that pool are then assigned at random. Both cases still exist and can be opened, but they're no longer part of the current regular case pool. So today, picking up the case you need on a marketplace is usually easier than counting on an in-game drop.
Out of 1,000 possible pattern indexes, only #402 counts as a true Stiletto White Gem. If a given Stiletto Urban Masked has already dropped, the odds of that specific index are roughly 1 in 1,000, assuming paint seeds are evenly distributed. But the overall odds of pulling #402 straight from a single case are far lower than that: first the rare special item has to drop, then specifically the Stiletto, then specifically Urban Masked — and only then that specific index.
The second route opened up after Trade Up Contracts were expanded in October 2025. Five regular Covert skins can be traded for one regular knife or a pair of gloves from the rare-special-item pools tied to the input skins used. Five StatTrak Covert skins yield a StatTrak knife. The contract doesn't let you choose the specific knife model, finish, or pattern index, though, so targeting a Stiletto Knife | Urban Masked #402 this way isn't possible.
Price and How to Verify the Pattern Before Buying
On LIS-SKINS, a regular Stiletto Knife | Urban Masked with no pattern specified runs roughly $140 to $180 depending on wear, and the StatTrak version roughly $160 to $240. That's an aggregate price by wear, not by pattern: marketplaces, LIS-SKINS included, show the cheapest listing in each wear bucket but don't filter by pattern index separately. That means a #402 copy can sit in the general listings priced like an ordinary one if the seller hasn't flagged the number — and the reverse happens too, with inexperienced sellers sometimes overpricing a pattern that only loosely resembles a White Gem.
So the only reliable approach is to check the listing's own pattern before paying: the pattern index is part of the item's data, which you can confirm by inspecting that specific copy. Confirmed #402 copies on specialized pattern trackers sell for several times the aggregate Urban Masked price — by those trackers' own estimates, the number runs into the thousands, though the exact price always depends on the specific listing and wear.
Is Hunting a White Gem Worth It
A White Gem is a collector's item, not something built for a quick flip: demand for one specific pattern on one specific knife model is a narrow pool of buyers who actually track rare pattern indexes, not the broad market. The rarity of #402 comes down to only one of 1,000 indexes producing this specific White Gem pattern. New copies can theoretically still turn up from opening existing Horizon Case and Danger Zone Case units or through a suitable Trade Up Contract, but there's no way to target #402 specifically. That rarity makes #402 an interesting collector's piece, but on its own it doesn't guarantee the price will rise. It cuts the other way for resale — finding a buyer for one specific rare listing can take weeks, and liquidity runs lower than popular Case Hardened patterns or top Doppler phases that trade constantly. As with any rare knife, what drives the value here is the rarity of that specific index plus the blade's condition, not the skin's name recognition.
Frequently Asked Questions
What is the White Gem on the Stiletto Knife Urban Masked?
It's pattern #402 — by community classification, the only index where the gray stencil work is barely visible and the blade reads as clean white. Every other Urban Masked index keeps a noticeable amount of gray.
Is there a cheaper alternative to a true White Gem?
Yes, patterns #718 and #820 (Tier 2), along with #37, #52, #161, #220, #372, and #509 (Tier 3), give a mostly white blade with some gray still visible — they're noticeably cheaper and easier to find, though they don't carry true White Gem status.
Can you get a White Gem through cases or crafting?
Not directly: the Stiletto sits in the rare special item pool of the Horizon Case and the Danger Zone Case, and the pattern index is assigned at random. A suitable Trade Up Contract can theoretically also yield a Stiletto Knife | Urban Masked, but it doesn't let you choose a specific pattern index. So targeting #402 specifically isn't possible through either route.
How do you confirm a listing is actually pattern #402?
Check the pattern index on that specific copy before buying rather than trusting the listing's title or wear: marketplaces aggregate listings by wear, not by pattern, so a seller can mislabel the number or skip it entirely.
