Frequently asked questions
Why use quartz as the main stone in a silver necklace?
Set raw and large, quartz shows its own growth geometry rather than a cut imposed on it. The silver frame is built around the crystal, so the stone stays the subject of the piece.
Are the crystals in these necklaces cut or polished?
No. Each kept its growth faces and terminations and is set in the shape it formed in. That is also why no two pieces repeat in shape or tone.
Where does the green and brown colour in quartz come from?
Trace elements and irradiation during growth, not treatment afterwards. Clear quartz is the base form of the same silicon dioxide.
How much does a STRUGA quartz crystal necklace cost?
From Rp 15,150,000 to Rp 18,710,000 depending on the stone, each on a 75 cm chain. Shipping is worldwide.
Do these quartz stones have any special properties?
Not that we will claim. Quartz carries more folklore than any other stone, and all of it is cultural history rather than a property of the object.
Can a piece be remade once the stone is sold?
Yes. The crystal itself is unrepeatable, but the same frame, chain and finish are made again with a newly chosen stone in about two weeks.
How do I clean silver jewelry with a raw quartz stone?
Cloth or silver cleaner on the metal, no ultrasonic cleaning. Raw quartz keeps internal fractures that ultrasound would find.
