The quartz family covers several of the most common beads: clear quartz, amethyst, rose quartz, smoky quartz, and citrine. They share the same base mineral but differ in trace elements and color. Clear quartz is colorless and transparent to translucent. Amethyst ranges from light lavender to deep purple, often with color zoning that is darker toward the tips. Rose quartz is a pale to medium pink, usually translucent with a soft, cloudy look rather than sharp transparency. Smoky quartz runs from light gray-brown to near black. Citrine is yellow to amber; much of the citrine sold is amethyst that has been heated to shift its color, while natural citrine is less common and usually a paler, sometimes slightly greenish yellow.
Lapis lazuli is a deep blue rock speckled with tiny gold flecks of pyrite and white veins of calcite. The blue comes from the mineral lazurite, and a good piece shows an even, rich blue rather than a washed-out or heavily white-streaked surface. Turquoise is an opaque blue to greenish blue, often with a matrix of darker veins running through it. The matrix pattern is normal and helps tell real turquoise from solid blue imitations; a completely uniform blue with no matrix can be a sign to look closer.
Agate and chalcedony are microcrystalline quartz, so they form in fine bands rather than large clear crystals. Agate shows layered bands of color, and carnelian is the orange to reddish brown form of chalcedony. These stones often have a waxy, even glow rather than a glassy flash. Because the color comes from fine banding, you may see gentle stripes or clouds rather than a single flat tone.
Natural crystals commonly carry small internal features: thin mineral needles, tiny dark points, or faint cloudy areas. These are part of how the stone formed and are expected in most beads. Uniform, glassy pieces with no features at all can be natural, but they can also be glass or synthetic, so features are one clue rather than a verdict on their own.
As a quick habit, look at how the color sits. Natural color tends to vary a little from bead to bead and sometimes within a single bead. A strand where every bead is the same flat shade, with no variation and no internal texture, is worth a second look before you buy.
A polished bead shows only a slice of the stone, so the color you see is the body color rather than the full crystal. That is why two beads from the same material can look slightly different once shaped, and why a strand is sorted to match. Knowing this helps you read a strand as a finished object rather than a raw specimen.
Knowing the material also tells you how to care for it, because softer and more porous stones need different handling than hard quartz. The care articles in this series go into water, sun, and wear in detail; here the point is simply that naming the stone correctly is the first step to keeping it in good shape.
The fastest way to recognize stones is to handle a few real pieces and compare them side by side. After you have seen true amethyst next to true citrine, and turquoise next to a blue glass copy, later identifications get much easier. Your own reference set, even a small one, beats any single description.
