Is Rose Quartz hard enough for everyday rings?

Mostly. At a Mohs hardness of 7, Rose Quartz stands up to routine wear, though sharp knocks and abrasive dust can still mar it over years of daily use.

How can I tell Rose Quartz from pink glass?

Rose Quartz and pink glass can look alike to the naked eye, but they differ in measurable properties — refractive index (1.544–1.553 for Rose Quartz), specific gravity (2.65), and hardness (Mohs 7). A gemologist confirms the distinction with a refractometer and loupe; the Jewelry Identifier app gives a fast first read from a photo.

Colors

Rose Quartz is found in pink. The body color, its saturation, and how evenly it spreads through the stone are among the strongest drivers of value.

How to tell real from imitation

No single test settles it, but a few grounded checks quickly narrow things down for Rose Quartz. Hardness, brilliance, and the list of stones it is commonly confused with all give you something concrete to look for.

Scratch resistance: genuine Rose Quartz sits at Mohs 7, so it should resist scratching from softer materials — a stone that mars far too easily is suspect.
Brilliance & luster: Rose Quartz shows a vitreous luster and a refractive index of 1.544–1.553; imitations often look glassier or flatter under the same light.
Density: a real Rose Quartz has a specific gravity near 2.65, so it feels heavier or lighter in the hand than many look-alikes of the same size.
Commonly imitated by: pink glass, pink chalcedony. If a deal looks too good, suspect one of these substitutes first.
Fast first read: photograph the stone in the Jewelry Identifier app to estimate the gemstone and its likely value range, then confirm anything important with a gemological lab.

Common treatments

none typically

Treatments are routine for many Rose Quartz stones, but they materially affect value and should always be disclosed — an untreated, lab-certified stone commands a clear premium over a treated one.
