The 4 Cs

The 4Cs – Cut, Color, Clarity, and Carat Weight – form the cornerstone of diamond assessment, shaping their visual appeal, value, and overall character.


The cut of a diamond determines its captivating sparkle. Explore classic round, elegant princess, or vintage-inspired emerald cuts. Each cut interacts with light in its unique way, showcasing the diamond’s brilliance and fire. A well-cut diamond reflects your love’s radiance, ensuring a timeless and dazzling presence.

Different diamond cuts


Diamonds come in a spectrum of colors, from icy whites to enchanting yellows and pinks. The GIA color grading scale helps you choose your desired shade. Opt for a colorless diamond for a traditional look or embrace a fancy color diamond to express your individuality and creativity.

Clarity speaks to a diamond’s internal purity. Our selection ranges from Flawless to Included, allowing you to strike a balance between brilliance and budget. Embrace the unique birthmarks within the diamond, known as inclusions, as they make each stone a one-of-a-kind work of art.

Carat Weight

Carat weight measures a diamond’s size, not its quality. Select a carat weight that resonates with your sentiments and budget. A larger diamond makes a bold statement, while a smaller one exudes delicate charm. Whichever you choose, it signifies the depth of your love.

Exploring Diamond Alternatives: Lab Grown Diamonds, CZ, and Moissanite

While diamonds are timeless and exquisite, modern couples have a plethora of options when it comes to choosing the perfect gemstone for their engagement ring. Lab grown diamonds, Cubic Zirconia (CZ), and Moissanite are three popular alternatives to traditional mined diamonds, each offering unique qualities that cater to different preferences.

CZ vs Moissanite vs Diamonds

Lab Grown Diamonds: Ethical Elegance

Lab grown diamonds are a sustainable and ethical choice that mirror the brilliance and beauty of mined diamonds. They are created in controlled environments using advanced technology, ensuring that each stone is of the highest quality. With the same chemical composition and physical characteristics as natural diamonds, lab grown diamonds offer a stunning and responsible option for your engagement ring.

Cubic Zirconia (CZ): Affordable Brilliance

CZ is a synthetic gemstone known for its impressive brilliance and affordability. While it may not possess the same hardness as a diamond, CZ offers remarkable sparkle that can easily mimic the appearance of a genuine diamond. This option allows you to achieve a stunning look without compromising your budget.

Moissanite: Fire and Brilliance

Moissanite, a lab-grown gemstone, is cherished for its exceptional fire and brilliance. With a higher refractive index than diamonds, moissanite reflects light beautifully, creating mesmerizing flashes of color. Its ethical and sustainable production makes it an attractive choice for environmentally-conscious individuals seeking an eco-friendly alternative.

Choosing between these diamond alternatives ultimately depends on your personal style, values, and preferences. Whether you opt for the classic allure of lab grown or mined diamonds, the affordability of CZ, or the captivating charm of moissanite, The Hamilton Gold Company is here to guide you in making a choice that perfectly reflects your love story. Each gemstone tells a unique tale, and we're dedicated to helping you find the ideal chapter for your engagement ring.
