Two Shattered Glass D20s, Two Different Materials
The Shattered Zircon Garnet and Shattered K9 Rainbow are both Boulder 30mm glass D20s with gold font, both hand-carved, both listed at USD 22.05 against a USD 35.00 comparison price, and both available only in the Standard variant. The meaningful choice is not the form factor—it is the material and the visual effect each one produces.
Zircon Garnet uses zircon glass, a material the catalog describes as used for filling outdoor fireplaces. K9 Rainbow uses highly reflective K9 rainbow glass. That single material difference drives the color behavior, the durability language, and the way each die reads at the table.
What the Catalog Confirms About Each Die
- Shattered Zircon Garnet - Gold Font Boulder® 30mm Glass Dice: Made using zircon glass—a material used for filling up outdoor fireplaces—with a shattered effect and stone-like hardness. The zircon base explains why this die is framed around toughness and a shattered visual rather than pure transparency.
Shattered Zircon Garnet - Gold Font Boulder® 30mm Glass Dice - Shattered Zircon Garnet - Gold Font Boulder® 30mm Glass Dice: The material can withstand up to 1300° F, and the catalog states the die will last thousands of DnD sessions, if not more. This is the strongest durability claim in the comparison, and it is specific to the Zircon Garnet.
- Shattered K9 Rainbow Glass - Gold Font Boulder® 30mm Glass Dice: Hand-carved in highly reflective K9 rainbow glass that displays a different color every time you look at it from a different angle. The K9 Rainbow is defined by angle-dependent color shift, not by a heat or hardness specification.
Shattered K9 Rainbow Glass - Gold Font Boulder® 30mm Glass Dice - Shattered K9 Rainbow Glass - Gold Font Boulder® 30mm Glass Dice: Described as delicate-looking and transparent yet incredibly durable. The catalog gives a durability impression for K9 Rainbow, but without the numeric temperature or session-count claims attached to Zircon Garnet.
Color and Light: Amber Shatter vs Prismatic Shift
The two dice create very different table presence. Zircon Garnet is described as having a luxurious amber hue and a shattered effect, with the material shimmering under light. K9 Rainbow is described as prismatic and blindingly beautiful, reminiscent of a Displacer Beast bending light.
- Shattered Zircon Garnet: Warm amber tone with a shattered internal look. The catalog emphasizes shimmer under light and a stone-like hardness rather than color change.
- Shattered K9 Rainbow: Highly reflective glass that shows a different color at every viewing angle. The effect is active and prismatic, not a fixed hue.
Durability Language Is Not Symmetrical
Zircon Garnet carries the more explicit durability evidence: a 1300° F tolerance and a claim of lasting thousands of sessions. K9 Rainbow is called incredibly durable, but the supplied catalog does not attach a temperature rating or a session-count claim to it. That does not mean K9 Rainbow is fragile—it means the two products are not documented to the same level on this point.
If durability under heat or long-term wear is your deciding factor, the Zircon Garnet record gives you more to work with. If you are choosing primarily for visual effect, the K9 Rainbow's angle-dependent color is the clearer differentiator.
Practical Buying Considerations
- Hand-carved variation: Both listings state the dice are made by a trained professional but, due to natural materials and hand carving and sandblasting, slight variations should be expected. Neither die is a mass-identical finish.
- Sourcing: The Zircon Garnet listing says zircons are sourced directly from metamorphic deposits in the US and Central America. The K9 Rainbow listing does not include a sourcing statement in the supplied evidence.
- Care instructions: Both listings point to a separate glass dice maintenance guide. The supplied evidence does not include the steps themselves, so follow the linked guide rather than assuming a cleaning method.
- Size and format: Both are Boulder 30mm glass D20s with gold font. If you want a matching set, the catalog evidence here covers these two D20s, not a full 30mm glass dice set in either material.
What the Catalog Does Not Settle
The supplied records do not confirm weight, exact dimensions beyond the 30mm Boulder designation, edge sharpness, or rolling balance for either die. They also do not confirm whether the gold font is painted, inlaid, or etched. Those details may exist elsewhere, but they are not part of the evidence used here.
For a glass D20 for DnD, both options share the same core format and price. The honest split is this: choose Shattered Zircon Garnet for the documented heat tolerance, stone-like hardness, and warm shattered amber look; choose Shattered K9 Rainbow for the prismatic, angle-shifting color effect and its lighter, more transparent appearance.
