{"product_id":"star-rose-quartz-madagascar-aaaa-gem-74514","title":"Star Rose Quartz Rough 20mm — Madagascar Cabbing Gem","description":"\u003cp\u003eThis is \u003cstrong\u003elapidary rough\u003c\/strong\u003e rather than a finished piece, and it is worth being clear about that from the start. Each is a tumble polished lump of \u003cstrong\u003estar rose quartz from Madagascar\u003c\/strong\u003e, roughly \u003cstrong\u003e20 mm\u003c\/strong\u003e across with a generous \u003cstrong\u003e15 to 18 mm\u003c\/strong\u003e of depth, sold per piece. The tumbling leaves smooth flat sides, which is exactly what you want for judging clarity and finding your axis before the saw comes out, but it also means what arrives is raw material with the best part still locked inside it.\u003c\/p\u003e\n\n\u003cp\u003eWill the star show on the rough as it is? No, and this is the thing to understand before buying. \u003cstrong\u003eAsterism\u003c\/strong\u003e needs a curved surface to gather and focus light into rays, so a flat sided piece simply cannot produce one. Cut and polish it into a rounded dome, a puffed round or a double sided heart, and the six ray star appears. In rose quartz the effect is \u003cstrong\u003ediasterism\u003c\/strong\u003e, meaning it shows in transmitted light, so you see the star by shining a concentrated point light through the back of the finished cabochon rather than from the front.\u003c\/p\u003e\n\n\u003ch2\u003eWorking with this rough\u003c\/h2\u003e\n\u003cp\u003eThe star comes from microscopic fibrous inclusions threaded through the quartz in a repeating orientation, the same inclusions responsible for rose quartz's pink in the first place. Because they align to the crystal's optical axis, orientation is everything. Wet the rough, backlight it with a single point source, and look for where the light gathers and organises. Cut so that the dome of your cabochon sits perpendicular to that axis, and the star lands centred. Get it wrong by much and you get a lopsided or absent star from material that was perfectly good. The generous depth here is deliberate, giving you room to cut a properly puffed double sided shape rather than a shallow dome that swallows the effect.\u003c\/p\u003e\n\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Natural star rose quartz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOrigin:\u003c\/strong\u003e Madagascar\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eForm:\u003c\/strong\u003e Tumble polished rough, flat sided\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize:\u003c\/strong\u003e Approximately 20 mm, 15 to 18 mm thick\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade:\u003c\/strong\u003e AAAA gem grade, clean\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChakra:\u003c\/strong\u003e Heart\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSold:\u003c\/strong\u003e Per piece\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eWhat else you can do with it\u003c\/h2\u003e\n\u003cp\u003eCabbing is the obvious route, but the cleaner sections face well for anyone who prefers faceting, and plenty of people skip the workshop entirely and wire wrap the tumbled form as a raw focal pendant. Rose quartz stays the \u003cstrong\u003eheart\u003c\/strong\u003e stone whatever you do with it, tied to \u003cstrong\u003ecompassion\u003c\/strong\u003e and \u003cstrong\u003eself acceptance\u003c\/strong\u003e, and the star variety is often treated as a focused version of that, an anchor point rather than a diffuse glow. One care note that carries into the finished piece: rose quartz fades under sustained ultraviolet light, so keep it out of long direct sun.\u003c\/p\u003e\n\n\u003cp\u003e\u003cem\u003ePlease note: crystals are not a substitute for professional medical advice, diagnosis, or treatment.
