[Source] Flat back faceted stones


#1

I am looking for a source of flat back faceted stones and cabochons
of various shapes. Glass and synthetic material is acceptable but not
plastics. Can you help?

Thanks in advance,
Richard Langbert

Swarovski is always a good choice for flat back faceted crystals.
You can find the best prices at Fire Mountain Gems or MonsterSlayer.
Some great cabochons can be found at Magpie Gemstones or
Unconventional Lapidarist.

I was planning on posting an almost identical question when I saw
this one.

I’m searching endlessly – and driving myself crazy – for someplace
to buy rose-cut cabochons. Stachura has a limited selection, Richard,
at pretty great prices, especially the garnets. I have purchased
some, and they’re beautiful. But I would love to be able to get
crystal quartz rose-cuts and possibly some other stones in quantities
of more than a couple at a time. Please help me so I can get off the
computer and into my studio!

im interested in a flat back faceted stone but i am looking for one
along the lines of 50 mm does anyone know where i could get that? its
going to be for a mold making and i do not think that i could do it
with a regular stone, it needs to be flat backed. not to mention,
when i pour the rubber mold in it will be much easier if the stone
is flat on the bottom. so that being said does anyone know of where i
can get a hold of any 50mm stones, they can range from cubic
zirconia to anywhere along the lines of turquoise or aquarmarine,
amethste even

The only place I’ve seen faceted stones is gembiz.com

I too would like to know of any other web site.

The suggestion of swarovski crystals in flat backed faceted stones
is a good one.

You are unlikely to find precious natural gems in flat back cuts,
because the pavilion of the stone acts as a set of mirrors, returning
light to the eye. They work on the same principle as the reflective
taillights in a car, although they should return more complex
reflections.

The angles on the pavilion of a faceted stone are constrained by the
"critical angle" for the particular material. At angles flatter than
forty degrees, in quartz, light is lost through the back of the stone
rather than reflected. A stone with flatter angles will appear very
dull unless it is mounted in a reflective setting, which lowers its
value. Stones with higher refractive indexes require even sharper
angles.

Rose cut, “flat back”, faceted top are available in diamond, citrine,
peridot, iolite, rose quartz, garnet that I know of.

I don’t know if this came through last time, but I posted the wrong
address for a web site. I posted gembiz.com it should be
www.gemsbiz.com

Thanks,
