Frequently asked questions

• Is Picasso Jasper actually jasper?

  No — despite the trade name, Picasso Jasper is metamorphosed limestone or marble, not a quartz-based jasper. The linear black, tan, and cream brushstroke patterns that give the stone its name come from mineral inclusions that migrated through the carbonate matrix during metamorphism. True jasper is a microcrystalline quartz with a Mohs hardness of 6.5–7, while Picasso Jasper sits at 3–4. The name is well-established in the bead trade and won't change, but the mineralogy matters for how you design with it and how you advise customers on care.
• How should I plan care for finished pieces using Picasso Jasper?

  At Mohs 3–4, this material is soft enough to scratch against harder beads, metal findings, and even fingernails over time. It works well for earrings, pendants, and bracelets worn occasionally — but skip rings and daily-wear pieces that take abrasion. Calcium carbonate reacts with acids, so keep finished jewelry away from perfume, hairspray, citrus, vinegar, and sweat where possible. Clean with a soft dry cloth or a barely-damp cloth with mild soap; avoid ultrasonic cleaners, steam, and prolonged soaking. Store separately from harder stones like quartz, agate, or tourmaline to prevent surface scuffs.
• What does Picasso Jasper pair well with in a design?

  The earthy palette — warm tans, ivory, charcoal, and occasional rust — bridges neutral and grounded designs. It pairs cleanly with matte onyx, smoky quartz, bronzite, petrified wood, and unpolished bone or horn for a rustic or southwestern feel. Brass, antiqued copper, and oxidized sterling pick up the warm undertones better than bright silver or yellow gold. Because the patterning varies bead to bead, designers often use 8mm and 10mm rounds as focal beads with smaller neutral spacers rather than running long uniform strands where the visual rhythm gets busy.
• Why does the pattern vary so much between strands?

  Picasso Jasper's brushstroke veining is the natural record of mineral migration through limestone or marble during metamorphism — no two blocks of rough cut the same way. One strand may run heavily cream with thin black lines, another may show dense tan-and-charcoal banding, and a third may include rust or olive tones depending on iron content. Cuts that show more surface area (larger rounds, donuts, star cuts) display the patterning more dramatically than small rondelles. If a specific color balance matters for a project, order a single strand first or ask about the current lot before committing to multiples.
• Is Picasso Jasper typically treated or dyed?

  Picasso Jasper is generally sold natural — the patterning is the selling point and dye would obscure it. The polish on rounds and rondelles is mechanical, not a coating or wax. The softer carbonate base means some suppliers stabilize cut beads with a clear resin to reduce chipping during stringing, though this is less common than with turquoise or chrysocolla.
