If you own a UV laser engraver or plan to start a personalized gift business, you’ve probably heard about K9 crystal.
But most buyers run into the same questions:
- Where is the best source for real K9 crystal, not decorative glass?
- What is a reasonable price for K9 crystal blanks?
- How can you identify it’s a real K9 crystal?
This guide answers those questions, then explains the technical details behind them, so you can buy with confidence and avoid costly mistakes.
Where to Find the Best Source for K9 Crystal
Choosing the right source matters more than most people expect.
- Laser Engraving Companies
Laser engraving manufacturers such as ComMarker and Cockpit3D offer K9 crystal blocks specifically selected for laser engraving.
In ComMarker, every single K9 crystal piece is checked to ensure it meets the standards, so you can buy with confidence.
- Craft & Engraving Retailers
Platforms like Amazon, Etsy, and local craft shops sell K9 crystal blanks.
But these shops can’t offer large bulk K9 crystal and sometime offer fake ones or priced too high.
- Wholesale Platforms
Wholesale platforms such as Alibaba may offer lower unit prices.
But large quantities often need to be ordered, transportation times are long, quality is not always guaranteed, and returns can be challenging.
For beginners or small engraving businesses, this option carries the highest risk.
How to Identify Real K9 Crystal and Normal glass
To determine if a piece of glass is a true K9 crystal, you can use the following methods:
1.UV Flashlight Test: Shine a UV flashlight through the glass.
True K9 crystal will allow the light to pass straight through, forming a focused beam. Fake K9 glass will scatter the light or glow unevenly.
2.Laser Engraver Test: Place the glass under the laser point of a ComMarker UV laser engraver.
If it’s a real K9 crystal, you can see a clean, focused light beam instead of a blue light glow.

This happens because normal glass is made from a mix of different materials that are not evenly distributed.
These mixed components cause the laser light to break apart and spread in different directions, instead of traveling in a straight line.
What’s a Reasonable Price for K9 Crystal Blanks? (2026 Reference in USD):
Keychain‑size blanks: mostly under $10.
Small cubes (≈40–50 mm): roughly $6–$15.
Medium cubes/rectangles (≈50×50×80 / 80 mm): typically $8.90–$26.
Larger or bulk packs: Around $18–$70+ or more.
Red Flag:
If a product labeled “K9” is priced like regular glass, it probably is regular glass.
How to Price Engraved K9 Crystal Products
If you’re buying K9 crystal to sell engraved products, pricing matters.
When pricing your engraved K9 crystal products, you can use the following formula:
Retail Price = (Material Cost + Labor Cost + Overhead) × Markup (2–3x)
–Material Cost: Include the price of the K9 crystal blank and add 10% for breakage or failed engravings.
–Labor Cost: Typical rate of $35–$85 per hour.
–Overhead: Include laser maintenance, electricity, packaging, and shipping (typically 15-20% of total cost).
Pricing example:
| Product Type | Material Cost | Labor Cost | Overhead (20%) | Total Cost | Suggested Retail Price (2× markup) |
| Small Keychain (e.g., $5 blank) | $5.00 | $3 (10 min) | $1.60 | $9.60 | $19.20 |
| Small Cube (50×50×50 mm, $12 blank) | $12.00 | $7 (15 min) | $3.80 | $22.80 | $45.60 |
| Medium Cube (60×60×60 mm, $25 blank) | $25.00 | $18 (30 min) | $8.60 | $51.60 | $103.20 |
| Large Cube (80×80×80 mm, $40 blank) | $40.00 | $35 (60 min) | $15.00 | $90.00 | $180.00 |
