If you look inside your crystal prisms (near the top where the hole is), you may see what looks like a scratch by the top of the facets .This is NOT a flaw! A closer look will show a tiny trapazoid pattern-it is actually the new laser-etched SWAROVSKI TRADEMARK! <p>Every crystal component over 18mm in size (USED TO)carry the Strass signature (with the exception of Emerald and Bordeaux) etched into each item using a state-of-the-art laser technique.They have also introduced a Bordeaux Blue-Limited Edition-and it also does not have the Logo.
Swarovski has instituted this new trademark on its individual prisms to distinguish its quality and authenticity from competitor prism manufacturers, many of which have been copying Swarovski's faceting patterns and marketing techniques.
If it's not LOGO ETCHED then it is not Swarovski Strass! Watch out for copy cats and imitations! ALL of the Swarovski 8558 crystal balls have 8 rows of facets which distinguishes them as Strass.

There are a few changes being made by Swarovski.

Due to large increases in energy costs(which constitutes a major factor in the productiojn of crystal)-Swarovski prices have been increased in the last few months.While most items have increased 3-10% the following items have been increased considerably:

Hearts -8781-     28 and 40mm(20mm discontinued)

Stars -8815 -     20,28,40 and 50mm

Moons -8816-    20,30 and 50mm

Shell- 8817-       28 and 40mm

Starfish -8818-    28 and 40mm

Snowflakes -8811- 20,25,30 and 35mm

Leaf  -8805-         26,32 and 45mm

Production of these 8000 series has stopped already and they have moved to the 6000series.(Jewelry category).Also the 6000 series(above stated crystals) WILL NOT have the laser etched Swarovski Strass signature logo.

Some simple facts:

Swarovski Strass is 32 % leaded crystal

Swarovski Spectra is non-leaded

From most expensive to least:

For Swarovski crystal balls 8558 is 8 rows of facets-32% leaded-logo etched

  --------------------------8550 is 6 rows of facets-32% leaded-logo etched

---------------------------8551 is 6 rows of facets-no lead-no logo

Bordeaux and Emerald Swarovski crystals are NOT logo etched (I don't know why....)

Crystal becomes crystal when lead is added to glass.The % of lead varies.Most manufacturers are 24%-30% leaded (or non leaded).Swarovski has the highest lead content of 32%.

If you see 33% leaded...beware...as there is no such value.(I have only seen 33% leaded on EBAY!)

Swarovski does sell a cheaper version of Non -Leaded Crystals.These are called Swarovski Spectra.These DO NOT have the Logos and are not leaded-so they are not quite as brilliant-but it is still  optically pure.The lead helps refract the sun for greater rainbows. Swarovski crystals also have the most facets.Hope this guide will help you in buying your next crystal.
