Our Unique Lifetime Guarantee
Eternity Natural Emeralds feature the ExCel Process, the world's first and only clarity enhancement specifically created for emerald that is colorless and stable and is guaranteed for the lifetime of the emerald. Eternity Natural Emeralds are the only emeralds that come with a lifetime guarantee for the enhancement.
Clarity enhancement exists in 99% of all natural emeralds and accentuates their natural beauty. Therefore, it is important that enhancement materials do not add color to the stone, don't deteriorate within the stone, and can withstand normal cleaning. The ExCel Process accomplishes all of this - guaranteed!
The Guarantee states:
Eternity Natural
Emerald's™ ExCel® is a stable
process for enhancing the clarity
of emeralds. Emeralds have
been treated with essential
oils or other enhancements
since the time of Cleopatra.
Now the ExCel Process incorporates
state-of-the-art Polymer technology
to create a durable enhancement
that is guaranteed for life.
If the ExCel Process ever fades,
dissolves, deteriorates or
washes out, Eternity Natural
Emerald will at its sole discretion,
re-enhance the gemstone or
replace it with an enhanced
gemstone of equal or greater
value. This guarantee is limited
to the ExCel enhancement only
and specifically excludes cracking,
natural defects or other damage
to the gemstone.
In fact, The ExCel Process is the only enhancement for emerald that adheres to the guidelines published in a report in Gems & Gemology in Summer 1999 on Emerald Filling Substances which stated; 'A good filling substance should have certain properties:
. It should hide fissures
. it should flow into the fractures (i.e., be liquid, at least initially)
. it should hold up over time or else be easy to restore
. it should be removable or not have any physical properties that might later harm the stone (e.g., during jewelry repair or repolishing)
. It should also have an R.I. similar to that of the stone being treated.'
