Gemstone Guide

When we say hardness, we mean a gemstone’s resistance to scratching on the surface. You’ve probably heard that diamonds are the hardest substance. This means they are highly resistant to scratching other than by another diamond. There are gemstones, such as Sapphires and Rubies, that also have high levels of hardness. However, there are gemstones, such as Amethyst, that have low levels of hardness and scratch easily. Wear bridal jewelry with softer gemstones mindfully if worn on a daily basis. 

Toughness refers to a gemstone’s resistance to breaking and chipping. This is different than hardness. For example, Sapphires and Rubies actually have a higher toughness rating than diamonds because they are less likely to break and chip. While diamonds do not scratch very easily, hitting them at the right angle can cause damage. Gemstones, such as Tanzanite and Opal, with low toughness ratings should be worn with extra care. Using the right setting on an engagement ring can protect center stones that aren’t as tough.

When you think of a Sapphire center stone, what likely comes to mind is the gorgeous Sapphire engagement ring worn by Princess Diana and now Kate Middleton. However, did you know that Sapphire comes in every color of the rainbow, except red (which would make it a Ruby)? This versatile and durable gemstone is perfect for an engagement ring you’ll cherish.

Ruby is one of the most well-known and recognized gemstones in history with a strikingly deep red color. A Ruby’s warm glow in the sunlight makes it a vibrant option for an engagement ring center stone. With high value and durability, Ruby is a stunning and worthy choice for everyday wear.

Historically, many have mistaken Spinel for Ruby due to its bright red hue. However, Spinel also comes in stunning cobalt blue as well as vivid pinks and oranges. With colors that compare to Rubies and Sapphires, one of the best benefits to Spinel is the price point — perfect for an attainable, showstopping colored center stone!

Moissanite is becoming one of the most popular diamond alternatives for engagement rings. Originally discovered from the remains of meteorites, jewelry-quality Moissanite nowadays is primarily lab-grown and very cost-effective. While you will commonly find colorless Moissanite due to its resemblance of a diamond, you can also find it in a variety of colors. Moissanite is second only to diamonds when it comes to hardness and is actually twice as refractive as a diamond. This means you will see a truly gorgeous sparkle from this center stone.

Tourmaline has one of the most expansive color ranges of any gemstone. From brilliant blues and greens to vivid reds and pinks, Tourmaline touches a variety of hues and intensities. This makes it easy to find your perfect color! You might even find options that are bicolor — featuring an ombre effect between two or more different colors, such as Watermelon Tourmaline. While not quite as durable as other center stone options, the beauty of Tourmaline is hard to beat.

If you are looking to live out your Jackie Kennedy fantasy, then an Emerald center stone is for you! The eye-catching green hues of Emerald are unparalleled. When choosing an Emerald to be your center stone, look for those desirable bluish green to pure green tones with a vivid color saturation.

As the name suggests, Aquamarine’s hues resemble calm ocean waters. While many prefer the pure sky-blue tone of Aquamarine, its true color of greenish blue is an indication of an untreated gemstone and is seen as more valuable. This gemstone brings the perfect symbolism for a center stone because it has been historically thought to bring happiness in marriage and protection.

While many colored gemstones are chosen for their vibrant color, Morganite is a light and soft pink. Named after famous banker and gemstone collector J. P. Morgan, Morganite is often associated with financial prosperity. When cut, only the highest quality stones are crafted into jewelry-quality Morganite so you can feel confident of the quality of your center stone.

The absolute essence of the color purple, Amethyst is a well-known and popular gemstone due to its rich reddish-purple hues and attainable price point. Due to its affordable price tag, you can enjoy Amethyst in a variety of sizes and shapes without concern for budget.

While the most classic and recognizable of Pearls are white and cream colored, Pearls come in a variety of hues — from pinks and oranges to blacks and blues. You have your pick of sizes, shapes, colors, lusters, and more when it comes to pearls. However, be careful! This delicate gemstone damages easily.
