A Simple Guide to Gemstones

When it comes to jewelry, picking a gemstone that resonates with you is important. But with so many choices available, how can you narrow down to the one?

This guide will equip you with all you need to know about the gemstones we offer, so that you can make the most informed decision to memorialize your milestones.

PEARL | MOH Hardness: 2.5

When we see pearls, the first word that comes to mind is elegance. A sign of purity and wisdom for centuries, the pearl's soft hues are quite different from the bright sparkles of other gemstones. But that adds to their subdued and natural beauty. After all, these sea gems are the only stones in the world that come from living, breathing animals. 

Because of their delicate nature, our freshwater pearls need some extra love and care to keep them in luminous, perfect condition. But with our care tips, you can have your pearls lasting for years, and even generations, to come.   

Pearls have a neutral tone and brilliant luster, making them perfect for any gold of your choice. Yellow and rose gold can give a vintage look to your pearl, while white gold can add a modern twist. If you're interested in having pearls in your ring, we will recommend the best settings that can provide sufficient protection for this delicate beauty. 

 

QUARTZ | MOH Hardness: 7 

As one of the most abundant natural minerals on earth, quartz is a multifunctional gem with a myriad of uses, from making glass to forming crystal oscillators for watches and clocks. The clear quartz is also believed to possess magical healing properties – emotionally, physically, and spiritually. Is there anything this wonder stone can't do? 

There are so many varieties of quartz, but the one we're most in awe of is the rutilated quartz, which contains naturally occurring strands of rutile. While inclusions are usually frowned upon in crystals, rutilated quartz is valued for their very inclusions which add to their allure. It's an ethereal, whimsical stone that is perfect for that extra sparkle of something different. 

With the versatility of quartz stones, any setting of your preference would enhance its radiance beautifully. We personally adore rose gold, because its warm hues can complement your skin tone well while drawing significant attention to the quartz's glistening luster. 

 

AQUAMARINE | MOH Hardness: 8

Aquamarines are another member of the beryl family. These sea-blue gems were once known as the sailor’s gem, believed to ensure safe passage across stormy seas. Today, they’re symbolic of courage, faithfulness, and emotional healing.

Unlike emeralds, aquamarines typically lack visible inclusions. Their crystal blue hues and excellent clarity give these gems a wonderful shine, much like the clear waters of the sea that bring us soothing energy and calming relief.    

If you’re looking for “something blue”, the durability and everlasting clarity of aquamarine make it the perfect gem for you. While we think that this gemstone looks gorgeous in all settings, pairing it with rose gold makes it exceptionally alluring. But if you’re hoping for a more traditional, elegant look, white gold is a classic setting for this stunning blue gem.  

 

MORGANITE | MOH Hardness: 8

A member of the beryl family, morganite is the perfect gem for lovers of pink. Its gorgeous pastels of peach-pink hues evoke an enchanting romance, warming the soul with love and compassion.

Morganites usually do not have visible inclusions, and are revered for their durability, clarity, and everlasting brilliance. They are a great choice for brides who like an unconventional, romantic sparkle.

When it comes to setting, the warm hues of rose gold can accentuate the captivating pink of morganite beautifully. Paired together, you’ll have a ring that stands out beautifully.

 

EMERALD | MOH Hardness: 8

Together with morganites, emeralds are part of the beryl family. They are beloved for their vivid green hues, perfect for those who love the bold and untraditional.

Chromium, vanadium, and iron are the trace elements influencing the emerald’s color. It often comes with vine-like inclusions that are sometimes called “jardin” (French for garden). We think that these inclusions really add to the allure of these beautiful green gems, don’t you?

Yellow and rose gold settings will complement the emerald’s hue and brilliance elegantly, giving it a soft, regal touch. On the other hand, its bold green color can really pop against a white gold setting, creating a stunning contrast.

 

SPINEL | MOH Hardness: 8

Spinel is a natural gem that’s in its own mineral group, although it’s often been mistaken for ruby or sapphire because of their similar beauty and brilliance. Just like sapphires, they come in a mesmerizing rainbow of colors, ranging from near colorless to deep blues and reds.

Spinel’s inclusions are typically eye-clean (not visible to the naked eye), though some stones can have very distinct and unique inclusions. Perhaps one of its biggest draws is its lack of heat treatment. The spinel that lands in your hands is beautiful in its most natural form, and that’s what makes it so exquisite.   

Durable enough for everyday wear and dazzling in its colorful sparkles, the spinel is a great alternative to traditional choices. Cool tones, like blue and violet, look best in white gold; while warmer colors, like red and pink, will twinkle beautifully in yellow and rose gold.

 

SAPPHIRE | MOH Hardness: 9

Falling within the corundum family, the sapphire is one of the “Big Three” colored gemstones – the other two are ruby and emerald. For thousands of years, it’s admired for its dazzling array of colors, while its durability makes it a top choice for commemorating milestones like weddings and anniversaries.

In their purest form, sapphires are colorless (or white). Every sapphire stone is different – its hue is determined by different quantities and blends of iron, titanium, and chromium – so you’ll be getting a stone that is truly one-of-a-kind, made just for you.

With these natural variations, sapphires are perfect for customizing and crafting bespoke rings. And because of their versatility, these lustrous gemstones dazzle in any setting, so it really depends on your preference.

White gold can give sapphires a clean, elegant look; while yellow and rose gold can really help the color of blue sapphires stand out more.

 

MOISSANITE | MOH Hardness: 9.25

Being second in line for durability, moissanite is a popular diamond alternative. Moissanites are strong enough to last for generations, even rivaling diamonds in their resistance to scratches.

Moissanites are exclusively man-made in the market these days, grown using the same silicon carbide crystals found in their natural forms. Compared to diamonds, moissanites have a higher brilliance rating and a higher refractive index (or “fire”). They also lack the inclusions and defects of natural diamonds. Under light, moissanites can truly sparkle like no other.

For similar quality and beauty at a more flexible price-point, moissanites are a great choice for engagement and wedding rings. At Lucy & Mui, our stones are sourced from Charles & Colvard’s Forever One Moissanite - we offer only the highest grade - colorless (color grading of D to F). 

Traditionally, white gold settings are preferred for colorless stones, but yellow and rose gold settings are becoming popular as well. Many people (us included!) like the natural and warm appearance these settings give to the moissanite stones. 

 

MINED DIAMOND | MOH Hardness: 10

Mined Diamonds

Known for being the toughest natural stone on earth (with a perfect score of 10), it’s no wonder diamonds are a top pick for engagement rings. We adore them not just for their resilience, but also their symbolic reminder of love, romance, and lifelong commitment.

About a hundred miles underground, heat and pressure from the earth crystallize carbon into diamonds. Mined diamonds undergo a long journey – from the scorching belly of the earth to hardworking diamond miners and skilled craftsmen – to find their forever homes with you and your loved one. At Lucy & Mui, our mined diamonds are conflict-free; we commit to the highest ethical standards because we believe in better. So rest assured, the diamond that lands in your hand comes with love.

For a near colorless diamond (ranging from G to I), a white gold setting will be most suitable to accentuate its brilliance. Diamonds tend to show a warmer tint with yellow and rose gold settings, so bear that in mind when you’re choosing your metal.

 

LAB-GROWN DIAMOND | MOH Hardness: 10

Also known as cultured diamonds, lab-grown diamonds are created in laboratory environments that mimic the conditions under which natural diamonds are formed. They are made of actual carbon atoms, arranged in the characteristic diamond crystal structure.

So yes, lab-grown diamonds are still diamonds! They have the same physical, chemical, and optical qualities as natural diamonds. In fact, it’s almost impossible to tell them apart, unless you’re using specialized equipment.

Lab-grown diamonds are friendlier to your wallet, but the lower cost doesn’t translate to a compromise in quality and value. They are graded just like natural mined diamonds, using the same criteria like the 4Cs. While they are still relatively new to the industry, lab-grown diamonds are gaining more interest, especially among millennials who are paving the way for a more ethical, sustainable future.

Just like its natural counterpart, a lab-grown diamond will look best in white gold settings, which can enhance its brilliance even more.

 

ASTRAL DIAMOND | MOH Hardness: 10

Also known as “salt and pepper diamonds,” astral diamonds are the latest additions to our collection. The speckled appearance of these diamonds makes them incredibly unique, giving each stone its own flair and character. While we cannot deny the timelessness of a crystal clear diamond, astral diamonds truly stand out as an engagement or wedding ring, because of their unconventional beauty.  

Astral diamonds vary in their shades, from shimmering mercury to velvety charcoal. They get their color from trace elements of hydrogen mixed into the carbon. However, inclusions are the standout feature for these diamonds. They remind us that when we embrace our imperfections, our natural selves can truly shine.

What we love about astral diamonds is that they are very versatile. They pair well with yellow and rose gold settings, which can really bring out the color and patterns of the stone while adding a vintage and sophisticated touch. Meanwhile, a white gold setting will give a cooler, more contemporary look that is just as charming.
