Moissanite is a fabulous Diamond Alternative, a great cost effective and conflict free option for anyone who wants a diamond look without the diamond price tag. 

Moissanite is a fabulous Diamond Alternative, a great cost effective and conflict free option for anyone who wants a diamond look without the diamond price tag. 

Diamond, the hardest material on earth, is April's birthstone. Natural Diamonds are formed under immense pressure and heat, conditions only found 100s of miles below the Earth's surface. Because of its hardness Diamond is traditionally chosen along with 14k Gold to create durable and long lasting engagement rings. Here at Madelynn Cassin Designs we love diamonds as well as diamond alternatives including Moissanite, White Sapphire or White Topaz. Check out our selection on Colorless Gemstones here

Aquamarine - March Birthstone

BirthstoneMadelynn CassinComment

This ocean blue stone is a favorite among many including the lucky ones who have it as their birthstone. Aquamarine is a member of the Beryl family also related to Morganite (another favorite of ours!). This stone is a great option for an alternative engagement ring as the stone has a hardness of 7.5 to 8 on the Mohs Scale. Our favorite source, the GIA has this to say about Aquamarine: 

Aquamarine’s name comes from the Latin for seawater and it was said to calm waves and keep sailors safe at sea. March’s birthstone was also thought to enhance the happiness of marriages. The best gems combine high clarity with limpid transparency and blue to slightly greenish blue hues. Like many beryls, aquamarine forms large crystals suitable for sizable fashioned gems and carvings.

For more information about Aquamarine and images of it in the rough check out the GIA Encyclopedia.

Amethyst - February Birthstone

BirthstoneMadelynn CassinComment

This beautifully saturated purple Gemstone is used as February's official birthstone. Seen here in our Three Stone Halo Ring, it is set in between two Tsavorite Garnets. This bright purple gem has a MOHs hardness of 7 and is a member of the Quartz family. Due to its moderate price tag large specimens of amethyst remain fairly affordable in comparison to other gemstones.  For more great facts and lore about Amethyst check out our favorite Gemstone Encyclopedia from the GIA.

Citrine - November Birthstone

BirthstoneMadelynn CassinComment
Madelynn Cassin

This sunny yellow gemstone is the birthstone for November. Natural citrine is a very rare to come by, so most citrine you will find out in the marketplace is actually Purple Amethyst that has been heat treated until it glows the golden yellow we know as citrine. These two stones are both members of the quartz family, having varying levels of oxidation of iron found in the crystal. When heated the iron impurities in the purple amethyst are reduced resulting in the golden orange color. Citrine is a 7 on the MOHs hardness scale and is the most popular yellow gemstone on the market. 


Above we have two examples of our own designs that incorporate citrine. Our Trillion Shaped Chevron Band in Sterling Silver available here as well as our Extra Large 9mm Citrine stud earrings available here.

The Easiest at Home Way to Clean Your Bling

Madelynn CassinComment

Has your Bling lost its luster, does it look a little filled with gunk?... It's okay, you're not the only one! Here is our latest blog post about how to keep that ring of yours sparkling like WOW. Here's how:

Step 1: Find Your Ring

Step 2: Hot Water, Oxyclean, Toothbrush

Grab a bowl, some hot (not boiling) water, a pinch of Oxyclean and have a soft bristle toothbrush at the ready! Place your ring in the mixture of Oxyclean and water and proceed to WAIT for 10-15 minutes. Let those bubbles go to work! 

Step 3: Rinse and Scrub

Don't be alarmed! There might be some funky stuff floating around in your Oxyclean bath - all that mystery gunk has been loosened up and now needs to be scrubbed and rinsed out. Grab that SOFT bristle toothbrush and with the faucet running give the open space behind your stone a good old scrub. Rinse and scrub until it looks as though your ring has been officially de-gunked. 

Step 4: Dry that Puppy off and be AMAZED!




That's it! A simple soak and a gentle scrub can keep your ring looking stellar all the time. In order to minimize the amount of debris that can build up behind the stone take your rings off when applying hand lotion and rinse behind the stone every time you wash your hands. But, when the time comes this simple at home trick can remove more of the stubborn gunk that can take up residency behind your bezel. 

*****Always remember to keep you and your rings away from harsh chemicals including bleach and chlorine as they can damage the integrity of your ring! ****

Along with Opal - Tourmaline is used as the October birthstone. Here are a few facts about Tourmaline from our favorite source on Gemstone info the GIA Encyclopedia

Tourmalines come in a wide variety of exciting colors. In fact, tourmaline has one of the widest color ranges of any gem species, occurring in various shades of virtually every hue.
Many tourmaline color varieties have inspired their own trade names:

  • Rubellite is a name for pink, red, purplish red, orangy red, or brownish red tourmaline, although some in the trade argue that the term shouldn’t apply to pink tourmaline.
  • Indicolite is dark violetish blue, blue, or greenish blue tourmaline.
  • Paraíba is an intense violetish blue, greenish blue, or blue tourmaline from the state of Paraíba, Brazil.
  • Chrome tourmaline is intense green. In spite of its name, it’s colored mostly by vanadium, the same element that colors many Brazilian and African emeralds.
  • Parti-colored tourmaline displays more than one color. One of the most common combinations is green and pink, but many others are possible.
  • Watermelon tourmaline is pink in the center and green around the outside. Crystals of this material are typically cut in slices to display this special arrangement.

Sapphire - September Birthstone

BirthstoneMadelynn CassinComment

Looking for a birthday present for that special September baby in your life? Get a little inspiration from Sapphire, September's birthstone. Here are a few facts about Sapphires from our favorite Gem Encyclopedia - from the GIA.

Besides blue sapphire and ruby, the corundum family also includes so-called “fancy sapphires.” They come in violet, green, yellow, orange, pink, purple, and intermediate hues. Some stones exhibit the phenomenon known as color change, most often going from blue in daylight or fluorescent lighting to purple under incandescent light. Sapphires can even be gray, black, or brown.


Sapphire’s blue can be vivid and saturated, like it’s lit from within. 


It’s so durable, synthetic sapphire is used for the windows of supermarket scanners and spacecraft.


Sapphire often contains delicate intersecting needles of rutile that gemologists call silk.

MOHS - How hard is your stone?

Madelynn CassinComment

What is the Mohs scale? 

The Mohs scale of mineral hardness is a qualitative ordinal scale that characterizes the scratch resistance of various minerals through the ability of a harder material to scratch a softer material. It was created in 1812 by the German geologist  and mineralogist Friedrich Mohs and is one of several definitions of hardness in materials science, some of which are more quantitative.  Source (

Stones we love to use:

  • Diamond - 10
  • Moissanite - 9.5
  • Sapphire - 9
  • Ruby - 9
  • Spinel - 8
  • Topaz - 8
  • Emerald 7.5 -8
  • Aquamarine - 7.5 -8
  • Morganite - 7.5-8
  • Tourmaline - 7- 7.5
  • Citrine - 7
  • Garnet - 6.5 - 7.5
  • Oregon Sunstone 6.5- 7
  • Peridot 6.5 -7

For rings that are going to experience long term daily wear, such as an engagement ring,  we always recommend a hard stone to go with a more durable metal such as 14k Gold.

Keeping Your Piece Bright and Beautiful: Cleaning and Care Tips

Madelynn CassinComment

Does your piece lack the luster it once had? Stone look a little cloudy? Even have some interesting gunk building up under that bezel? Fear not! Here are a few quick and easy steps to return that sparkle in your favorite piece!

Simple Steps to Keep Your Ring Clean

1. Keep Those Hands Clean - Every time you wash your hands, take a minute to rinse the back side of your ring (underneath the bezel) this will help to prevent any gunk from starting to build up and cloud your stone. 

2. Need a deeper Clean? Grab your ring, some hot water, and a pinch of Oxyclean. Place your ring in the solution of Oxyclean and hot water for a 15 minutes, this will help to dissolve any built up skin cells, lotion, hand soap and any other things that make be hiding behind your stone! After the 15 minutes is up take a SOFT bristle toothbrush and give the area behind the stone a good scrub, this will help to remove the dissolved debris. Rinse under the faucet and BAM! Look at that puppy sparkle! 


Chlorine - including any found in hot tubs or pools, Harsh Cleaning Chemicals - they aren't good for you or your jewelry
