Here Are Some Important Things To Consider When Looking For The Perfect Stone

Durability & Hardness

Just like your love, your gemstone too has to stand the test of time. Gemstones are used in engagement rings to symbolize everlasting love, and it is very important to consider the durability and hardiness of the stone when making an informed decision. Minerals are classified by hardness according to the Mohs scale of hardness. The higher the hardness rating, the more durable the stone. “Soft” stones like moonstone and opal may be trendy and fashionable, but are susceptible to chipping, eroding, or breaking over long periods of everyday wear. Hard stones are ideal for daily wear, are resistant to scratches, and also appreciate in value over time.

Diamonds, being the hardest mineral substance on earth, has a rating of 10 in the Moh’s scale. Only stones that rank 7.0 or higher on the Moh’s scale are fit enough to resist events that will blemish, scratch, or damage the stone with everyday use. As such, gemstones such as sapphire (9.0 Moh’s), ruby (9.0 Moh’s), emerald (8.0 Moh’s), spinel (8.0 Moh’s), and alexandrite (8.5 Moh’s) are popular alternative choices to diamonds when selecting a jewel fit for the gesture of a lifetime. At Gemdaia, we only recommend gemstones that rank at 8.0 or higher on the Moh’s scale for your engagement ring.

Beauty & Sparkle

What’s a gemstone without a sparkle? The beauty and sparkle of any gemstone is what makes them precious and valuable. The optical characteristics of gemstones vary according to each mineral. The appeal and value of a gemstone are determined in the gem-industry by inspecting three factors: brilliance, luster, and fire.

  • Brilliance, as the word suggests, is the term used to determine the amount of light returned to the eye from a gem’s interior. Cutting and polishing techniques can be applied to increase a gemstone’s brilliance.
  • The luster of a gemstone refers to the property of reflectiveness on its surface. Prized gemstones reflect light better, as opposed to absorbing light, which gives stones a duller appearance.
  • Finally, the quality of light refracting throughout the stone is referred to as the “fire” of a gemstone. We encourage our clients to look closely into these properties when selecting their perfect stone . After all, a gemstone’s sparkle is a representation of the light of love, and it’s only fitting that you find the most beautiful sparkle to tell that story.

Is It A Good Match?

Think about the kind of jewel that personifies your partner. Not only should your engagement ring signify an everlasting love, it should, most importantly, win your partner’s admiration. Finding the perfect match for your better half is something that requires you to consider many factors such as style, gemstone type, hardness scale, color, cut, and price-range etc. before arriving at a decision. The task may sound daunting to many, but our helpful 12-step buying guide will simplify some of the most frequently occurring questions when choosing the ideal stone for the love of your life.

Investment Value

The value of gemstones is timeless. Besides being a beautiful embellishment that symbolizes your love for one another, a gemstone is an investment that appreciates in value over time. This makes it a valuable treasure that can be passed on through generations. It’s no secret that jewelry and gemstones make for great heirlooms. Make your choice the perfect representation of an undying love story that can be passed on from generation to generation.

Impress With Ingenuity

Just one glance is all it takes for an engagement ring on a finger to impress. Not only are they a deeply personal accessory, engagement rings are also a powerful social statement. The perfect balance of style, materials, and personality emanates a persuasive sense of confidence and character in an engagement ring. Achieving a luxurious look and feel for the ideal ring shouldn’t be something that intimidates you. At Gemdaia, we can help you design your own custom engagement ring to find the ideal balance between beauty, affordability, and the ability to impress at every social setting – including those with your in-laws!

Rated 10 on the Moh’s scale of hardness, diamonds are incomparable in their toughness to any other gemstone or mineral on earth.
