The Gemstone Engagement Ring: What You Need to Know Before You Buy
The Hook Choosing a vibrant colored gemstone as the centerpiece of an engagement ring
is a spectacular, highly personalized decision. However, an engagement ring is designed to be worn every
single day for a lifetime. Unlike natural diamonds, colored gemstones require a deeper understanding of
durability, maintenance, and expert craftsmanship before making a purchase. At the Dianoche Atelier, we
want to ensure your vibrant centerpiece stands the test of time.
The Mohs Scale: Understanding Hardness When selecting a gemstone, the most critical
factor is its hardness, which is measured by the Mohs scale. A natural diamond sits at the absolute top
with a perfect 10, making it incredibly resistant to scratches. Sapphires and rubies score a 9, making
them excellent, highly durable choices for daily wear.
However, other stunning gems like emeralds typically score between 7 and 8.5. This makes them
significantly softer, more brittle, and highly vulnerable to chipping or cracking upon impact.
Strategic Setting and Maintenance If you fall in love with a softer stone like an
emerald, it must be actively protected. We strongly advise against exposed, high-profile settings.
Instead, our master jewelers engineer secure settings—such as a protective bezel (a "cup" of gold) or a
tight diamond halo—to shield the gem's delicate edges from direct blows.
Furthermore, maintenance requires extreme care. While diamonds can be easily cleaned with ultrasonic
machines and high-pressure steam, subjecting an emerald or a heavily included gemstone to those intense
vibrations can cause it to shatter completely. They must be gently cleaned by hand.
The Dianoche Sizing Warning Here is a crucial trade secret: resizing a gemstone ring is
a highly risky procedure. Many colored gemstones simply cannot withstand the intense heat of a jeweler's
torch during the resizing process. Often, the stone must be entirely unset and removed before the gold
band can be altered, which increases the risk of damage. Therefore, we urge our clients to make every
possible effort to ascertain the exact, perfect ring size from the very beginning.
