Best Ways to Identify a Real Diamond
Discovering a genuine diamond is a captivating experience. Its
breathtaking beauty and brilliant sparkle make it the unrivaled king of
gemstones. However, distinguishing a real diamond from a counterfeit requires
careful attention to detail and finesse. Here are five simple methods to
identify a genuine diamond before seeking a professional gemologist's final
confirmation.
- Magnification
Test: Examine the diamond using a jeweller's loupe or a microscope. A natural
diamond possesses imperfections such as irregular shapes and sharp edges,
showcasing its origin from a mine. Look for clear-cut facet lines with
single refractivity. Be cautious of perfectly shaped diamonds with rounded
edges and scattered facet lines. Additionally, observe the metal on which
the diamond is mounted. A genuine diamond is typically set on pure gold or
platinum rather than gold-plated casting.
- Sandpaper
Test: Authentic diamonds lack scratches and abrasions, reflecting a
flawless shine as they refract light from their smooth, glossy surfaces.
To verify a diamond's authenticity, lightly scratch it with rough
sandpaper. As diamonds are one of the hardest substances on Earth, a
genuine diamond should remain unscathed, retaining its radiant luster.
Only a real diamond can cut another real diamond.
- Reflection
Test: Hold the diamond up to direct sunlight and observe how the rays
bounce off the stone. A genuine diamond exhibits a brilliant grey and
white sparkle with hints of rainbow-like colours at the edges. Conversely,
a fake diamond may display rainbow hues from the center without the
accompanying shimmering grey brilliance.
- Fog
Test: Clean the diamond and expose it to a gentle breath of warm air. Due
to its excellent heat conductivity, a genuine diamond should not retain a
layer of steam or fog. If the stone remains moist, it is likely an
imitation.
- Refraction
Test: The ultimate test for determining diamond authenticity is the
refraction test. Place the diamond on a plain sheet of paper and examine
its shadow. A genuine diamond will cast a dark shadow, characteristic of
an opaque gem, while displaying enchanting light dispersion through its
intricate facets. The scattered light creates a geometric shadow filled
with radiance and sparkle. Additionally, try placing the diamond over text
and check if the letters remain unchanged. A real diamond will appear
opaque and not magnify or distort the text, whereas a fake stone may
appear more transparent and reveal hints of the text underneath.
Although conducting these tests can
provide initial indications, consulting a professional gemologist is always
advisable for complete certainty regarding a diamond's authenticity. A genuine
diamond is truly a one-of-a-kind treasure, much like its fortunate owner. It's
no wonder this natural masterpiece is often referred to as a girl's best
friend!
