Antique-style glass door knobs can restore character to a vintage interior door, but the right choice depends on more than looks. Check the glass color and shape, the hardware finish, and—most important—the lock style and spindle or latch fit. The three options below lean toward clear glass rather than distinctly colored glass, so compare the listing details carefully if color is a priority.

PRIME-LINE Fluted Glass Knobs for Antique Mortise Locks
This PRIME-LINE set is designed for replacing worn or broken knobs on traditional interior doors with compatible mortise locks. It pairs clear, fluted glass knobs with classic bronze-finished bases, giving it a restrained vintage look rather than a bright pop of color.
The knobs measure two inches in diameter, and the set includes a three-and-a-half-inch steel square-drive spindle. That makes the spindle and existing lock system key parts of the fit check: this is not described as a complete replacement lockset, and compatible rosettes or other lock components may be needed.
Compared with the Amylove option, this set gives more specific guidance for mortise-lock use. It may suit you if your door already has that type of hardware and you want fluted glass with bronze details. The main limitation for shoppers seeking colored glass is that the supplied description identifies the glass as clear.
Pros:
- Fluted glass offers a traditional appearance.
- Bronze-finished bases coordinate with classic hardware.
- Includes a steel square-drive spindle.
- Designed for compatible antique or traditional mortise-lock doors.
Cons:
- Clear glass, not a specified colored-glass option.
- May require compatible rosettes or additional lock components.
Verdict: Choose this set if you have a compatible mortise lock and want clear fluted glass with bronze-finished bases; check your existing spindle and lock parts before ordering.
Amylove Fluted Glass Knob Set with Bronze Finish
Amylove’s set pairs glass knobs with bronze-finished hardware and includes spindles. The listing describes two sets, making this a possible choice when you need hardware for more than one door or want a spare set. The glass is described as a crystal-ball design, while the overall look is aimed at vintage or antique-style interiors.
The stated knob dimensions are about 2.32 by 2.05 by 0.6 inches. Measure the existing hardware and compare it with those figures before buying. The listing says the knobs suit many old or vintage interior doors, but it does not specify the same mortise-lock fit details as the PRIME-LINE set, so check your door’s mechanism and spindle requirements.
Its bronze finish and included spindles make it a straightforward-looking replacement option, but the supplied description does not identify the glass as colored. It also describes the materials as zinc alloy and glass, so this is best judged as a style-and-fit purchase rather than a match for shoppers who require a specific glass tint.
Pros:
- Listing states that two sets with spindles are included.
- Fluted glass and bronze finish suit vintage-inspired rooms.
- Provides stated dimensions to compare with existing knobs.
- Made with glass and zinc alloy, according to the product details.
Cons:
- Door and lock compatibility details are limited.
- The glass is not described as colored.
Verdict: Consider Amylove if you want two vintage-style knob sets with spindles, but confirm the package contents and hardware fit for your doors before purchasing.
Floresita Rose-Shaped Crystal Knob with Privacy Lock
The Floresita set stands apart because it includes a privacy lock for a bedroom or bathroom, rather than just replacement knobs for an existing mortise lock. Its description features rose-shaped, crystal-clear knobs with a zinc alloy base. However, the product title says “black brown,” while the supplied description calls the crystal clear. Check the listing images and specifications if the color is essential to your choice.
The set is described as fitting doors from 1⅜ to 1¾ inches thick, with an adjustable latch range of 2⅜ to 2¾ inches. It is also described as suitable for left- or right-handed doors, and an inner hex key is included for opening the privacy lock from outside. These details make it the most function-focused choice here, though it is not a direct match for a traditional mortise-lock replacement.
Its rose-shaped glass gives it a more decorative look than the fluted options, and the privacy function adds practical use for rooms where a basic passage knob is not enough. The trade-off is that it requires a latch installation and is described as a complete privacy-lock set, so check that style of hardware works for your door.
Pros:
- Includes a privacy lock for bedrooms or bathrooms.
- Listing gives door-thickness and adjustable-latch ranges.
- Rose-shaped glass offers a distinct decorative look.
- Described as suitable for either door handing.
Cons:
- Product title and description differ on the glass color.
- Privacy-lock hardware is not a direct substitute for every mortise setup.
Verdict: Pick Floresita when you need a decorative privacy-lock set and its stated door measurements fit; verify the color and hardware details before ordering.
How to Choose Antique-Style Glass Door Knobs
Confirm the glass color and finish
“Glass door knob” does not always mean colored glass. The PRIME-LINE description specifies clear fluted glass, and the Amylove description does not name a tint. Floresita’s title and description do not agree on color. If you want amber, green, blue, or another specific shade, confirm that the exact option you plan to order is shown and described as that color.
Match the knob to your door hardware
First find out whether your door uses an existing mortise lock, a separate latch, or another setup. The PRIME-LINE set is designed for a compatible mortise lock and includes a square-drive spindle. Floresita is described as a privacy-lock set with an adjustable latch. These are different hardware types, so a knob that looks right may still not work with your door.
Measure the spindle, latch, and door
Compare your current hardware with the measurements in the product listing. For the PRIME-LINE set, check the square-drive spindle and its stated length. For Floresita, compare your door thickness and latch backset with the listed ranges. For Amylove, compare the knob dimensions and check the spindle connection before purchasing.
Decide whether you need a passage or privacy function
A replacement knob for an existing interior lock may be enough for a hallway or living space. A bathroom or bedroom may call for a privacy function. Floresita is the only option here described with a privacy lock. The other two are replacement knob sets and should not be treated as complete privacy-lock systems based on the supplied details.
Check the number of sets and included parts
Confirm what comes in the package before you order. PRIME-LINE describes two knobs and a spindle in one set. Amylove’s description says there are two sets with spindles. Floresita is described as including lock accessories and installation instructions. Also check whether your project needs separate rosettes or other parts.
Consider how the design fits the room
Fluted glass has a more traditional, patterned look, while a rose-shaped knob is more decorative. Bronze-finished bases can complement classic hardware, but the supplied product descriptions do not establish that any option has a specific colored-glass tint. Compare the full knob and base together with your existing hinges and door finish.
Frequently Asked Questions
Are these knobs made with colored glass?
The supplied details do not confirm a distinct colored-glass option among all three products. PRIME-LINE describes its glass as clear, and Floresita’s title conflicts with its description about color. Check the product listing closely if a particular tint is a must-have.
Which option is designed for an antique mortise lock?
PRIME-LINE specifically describes its set as designed for existing mortise-lock systems using a square-drive spindle. Confirm that the included spindle and your lock components are compatible.
Do these products include complete locksets?
Not all of them. PRIME-LINE is described as replacement knobs and a spindle for an existing mortise lock. Amylove is described as knob sets with spindles. Floresita is described as a privacy-lock set with a latch and accessories.
Which option includes a privacy function?
Floresita is the only product in this selection described with a privacy lock. Its listing says the set is suited to bedrooms and bathrooms and includes an emergency opening tool.
Can I install one of these on any interior door?
No. Door thickness, lock type, spindle connection, and latch measurements can affect fit. Compare your current hardware with the product’s stated specifications before buying.
Are rosettes or other parts included?
The PRIME-LINE description notes that compatible rosettes and lock components may be required. Check each listing’s package details and inspect your existing door hardware to identify any additional parts you may need.
Final Recommendation
For a compatible antique mortise lock, the PRIME-LINE set is the clearest match because its spindle style and intended use are specified. Choose Amylove if you want the listing’s stated two sets of vintage-style knobs, after confirming fit and package details. Floresita is the best fit of these three when you need a privacy-lock set, provided its measurements match your door. None is clearly confirmed as a colored-glass choice, so verify the exact color before ordering if that is your main requirement.
