Materials Explained
Bohemian crystal is hand-cut high-index barium crystal made in the Czech Republic; Swarovski is Austrian machine-cut crystal produced to identical tolerances; K9 is a lead-free optical glass, usually made in Asia. Bohemian crystal disperses light into warm spectral color and every piece differs slightly, which is why it is specified for one-off statement chandeliers. Swarovski gives uniform, engineered brilliance. K9 is clear and affordable but throws far less color.
Side by side
| Bohemian (Czech) | Swarovski | K9 | |
|---|---|---|---|
| Origin | Czech Republic (Bohemia) | Austria | Mostly Asia |
| Composition | High-index barium crystal | Precision-formulated crystal glass | Lead-free optical glass |
| Cutting | Hand-cut by artisans | Machine-cut to fixed tolerances | Machine-pressed or machine-cut |
| Light behavior | Warm, colorful dispersion; varies facet to facet | Very bright, highly uniform sparkle | Clear and bright, little spectral color |
| Character | Each piece slightly different | Every piece identical | Uniform, mass-produced |
| Custom forms | Yes — built to brief | Limited to catalog components | Limited |
| Relative cost | Mid to high | High | Low |
Why composition changes what you see
Barium oxide raises the refractive index of glass — roughly 1.52 to 1.56 for high-index barium crystal against about 1.50 for ordinary optical glass — and, more importantly, raises dispersion: the degree to which the material splits white light into its component colors. That is the physical reason a genuine crystal chandelier throws flecks of red, green, and violet across a wall while a glass one only glitters white. The high barium content also softens the glass enough to be cut deeply by hand without shattering, which is what makes Czech hand-cutting possible in the first place.
Hand-cut versus machine-cut
A machine cuts every facet to the same angle, so a fixture built from machine-cut components sparkles in one predictable register. A Czech cutter works each piece on the wheel by eye, so facet angles vary by fractions of a degree from element to element. Walk past a hand-cut chandelier and the highlights fire unevenly, one after another. That irregularity is the entire aesthetic argument for Bohemian crystal, and it is the thing photographs of catalog fixtures never capture.
Which should you specify?
- Choose Bohemian crystal for residential statement pieces, hospitality lobbies, and any project where the fixture should feel commissioned rather than purchased — and where you want the form itself customized, not just the finish.
- Choose Swarovski components when a design must be reproduced identically across many rooms or many properties and consistency outranks character.
- Choose K9 only when budget is the governing constraint and the fixture is decorative rather than focal.
What Berkana supplies
Berkana works exclusively with Czech workshops, and sells hand-cut Bohemian crystal chandeliers, pendants, and sconces through representative agencies to interior designers, architects, and boutique retailers across America. Pieces can be taken from existing collections or designed from scratch to a room's dimensions. A Florida office and a Dallas Market Center presence support the American side.
Common questions
Bohemian crystal is hand-cut high-index barium crystal produced by Czech workshops, prized for deep irregular facets and warm dispersion. Swarovski is precision machine-cut crystal made to identical tolerances, giving a uniform, very bright sparkle. Bohemian crystal reads as artisan and unique; Swarovski reads as engineered and consistent.
Neither is objectively better — they are different products. For a one-off statement chandelier where character and custom form matter, hand-cut Bohemian crystal is usually the stronger choice. For a fixture that must repeat identically across many units, machine-cut crystal is more predictable.
K9 is an optical-grade glass, mostly produced in Asia, with a refractive index around 1.50. It is clear and inexpensive but has lower dispersion than Bohemian crystal, so it sparkles white rather than throwing spectral color. It is common in budget and mid-market chandeliers.
Yes, optically. A higher-index formulation raises the refractive index and dispersion of the glass, which is what produces the rainbow flare in a genuine crystal chandelier. It also softens the glass so it can be hand-cut deeply.
