Welo Opal
- Grading: IF

Opal is an amorphous form of silica, chemically similar to quartz, but containing 3%
to 21% water within its mineral structure. Gem grade opals usually have 6% to
10% water content. Opal is a sedimentary stone. Under the proper conditions,
water percolates through the earth, becoming rich in dissolved silicates. When
water enters a cavity, it deposits the silicates as microscopic spheres,
forming opals. If the spheres are uniform in size and shape and neatly stacked,
they will diffract light.
*CARE
(Welo Opal)*
Very heat sensitive, clean with soft clean
cotton cloth. If the Welo opal gets soaked with water, it will absorb water
internally and will take 3-14 days to dry out and return to it’s original beautiful
color. This is what’s called a “Hydrophane opal” which means that it has an affinity
to absorb water. Avoid wearing the gem where it will get rough treatment.
*CLARITY
CHART*
IF – Internally flawless; free of
inclusions
VVS – Very, very slight
inclusions; microscopic inclusions barely
seen under a loupe with 10x magnification
VS – Very Slight inclusions;
visible inclusions that can be seen under magnification and sometimes also with
the unaided eye.
SI – Small inclusions; inclusions
that are obvious under magnification and to the unaided eye.
I – Heavy or large inclusions
obvious to the naked eye
All gemstones
listed here have been cut by myself. I work exclusively with a precision
machine when faceting gemstones. This allows extra brilliance
and appeals only seen in precision-cut gems. Gemstones are cut at
their correct refractive index using digital precision, this facilitates making
the correct facet angles allowing the maximum amount of light to enter and
reflect back up through the table. This allows optimum brilliance
according to each gemstone's individual refractive index. Special care in
polishing ensures that the faceted gem is showcased in all its brilliance. The
introduction of precision faceting machines has revolutionized the art of gem
cutting allowing the gem cutter to unveil the inner beauty of every single
gemstone like it has never been done before. The cut of a gem is one of the
main values of a gemstone and each gemstone requires special attention in order
to unveil its potential beauty. If you're looking for that extra special stone,
I hope you find it here.
Sincerely,
Doug
