The cut is arguably the most important aspect of a diamond’s beauty. It refers to how well the diamond’s facets interact with light, creating sparkle and brilliance. A well-cut diamond will reflect light beautifully, while a poorly cut one may appear dull.

• Grades: Excellent, Very Good, Good, Fair, Poor
• Shapes: Round, Princess, Oval, Pear, Cushion, Emerald, and more
• Tip: A higher cut grade can make a smaller diamond appear larger and more radiant.

Diamonds are graded on a scale from D (colorless) to Z (light yellow or brown). The less color, the rarer and more valuable the diamond. However, lab-grown diamonds offer a more affordable way to access high-quality, colorless stones.

• D-F: Colorless (most desirable)
• G-J: Near Colorless (offers great value)
• K-Z: Noticeable color

Clarity measures the presence of internal inclusions and external blemishes. While inclusions are natural and unique to each diamond, they can affect light performance. Most imperfections are invisible to the naked eye in diamonds with higher clarity grades.

• Grades: FL (Flawless), IF (Internally Flawless), VVS (Very, Very Slightly Included), VS (Very Slightly Included), SI (Slightly Included), I (Included)
• Tip: Opt for "eye-clean" diamonds where inclusions aren't visible without magnification.

Carat refers to the weight of a diamond. While it often correlates with size, the cut can influence how large a diamond appears. Larger diamonds are rarer and more valuable, but balancing carat weight with cut, color, and clarity ensures value for your budget.

• Tip: A 0.9-carat diamond often looks nearly identical to a 1-carat stone but is significantly more affordable.

Shape reflects the overall form of the diamond, influencing its style and how it complements different settings.

• Popular shapes: Round (classic), Oval (elegant), Emerald (vintage), Princess (modern), Cushion (romantic).

Some diamonds emit a soft glow under UV light. While this feature doesn’t affect durability, it can impact a diamond’s appearance.

• Tip: A faint fluorescence can make near-colorless diamonds appear whiter, offering a cost-effective alternative.

All Una Diamond stones come with certification from reputable grading labs, ensuring authenticity and quality. Look for certificates from GIA, IGI, or similar trusted organizations.

• Why it matters: Certification provides confidence in your diamond’s characteristics and value.

Lab-grown diamonds, like those at Una Diamond, are indistinguishable from mined diamonds but come without the environmental and ethical concerns of traditional mining.

Before diving into specifics, ask yourself what matters most to you:

• Brilliance or Size? If sparkle is your priority, focus on the diamond’s cut. For size, prioritize carat weight.
• Budget Flexibility? Lab-grown diamonds allow you to access larger stones or higher quality within your budget.
• Aesthetic Preferences? Certain shapes and colors align with different styles. For example:

Understanding how the 4 Cs (Cut, Color, Clarity, and Carat) interact will help you get the most for your investment.

• Cut First: Always prioritize cut for sparkle. A poorly cut diamond can look dull, even with high color or clarity.
• Color Second: Opt for "near-colorless" grades (G-J) for a balance of beauty and value.
• Clarity Third: Choose "eye-clean" grades like VS1 or VS2—imperfections not visible to the naked eye.
• Carat Last: Once you’ve optimized cut, color, and clarity, focus on carat weight to fit your budget.

The shape of a diamond sets the tone for its overall look and can influence how large or sparkly it appears.

• Round: The most brilliant and popular shape, timeless and versatile.
• Oval: Elongates the finger, offering an elegant silhouette.
• Princess: A modern square cut with sharp lines and great sparkle.
• Cushion: Romantic and vintage, featuring soft, rounded edges.
• Emerald: A bold, sophisticated choice with step-cut facets for a mirror-like effect.
• Pear/Marquise: Unique and eye-catching shapes that can appear larger than their carat weight.

Tip: Narrow fingers may pair well with elongated shapes like oval or emerald, while broader bands can complement round or princess cuts.

The setting you choose not only secures your diamond but also enhances its appearance and reflects your personal style.

• Prong Settings: Elevate the diamond, maximizing light exposure for brilliance.
• Bezel Settings: Encircle the diamond for a secure, modern look.
• Halo Settings: Surround the center stone with smaller diamonds to add sparkle and size.
• Solitaire Settings: Simple, elegant, and timeless, focusing entirely on the center diamond.

Tip: Consider your lifestyle when selecting a setting. Active individuals may prefer bezel settings for added protection.

Diamonds are durable, but their settings and surroundings require care.

• Lifestyle Match: Active wearers may prefer robust settings, while intricate designs work best for occasional wear.
• Maintenance Needs: Prong settings require periodic tightening, while bezel settings offer easier upkeep.
• Cleaning: Regular cleaning with warm soapy water and a soft brush keeps your diamond sparkling.

Think beyond the purchase. A high-quality diamond with solid certification will hold its value over time. Lab-grown diamonds, while less tied to resale, offer exceptional quality and ethical peace of mind.

• Educate Yourself on Fluorescence: Diamonds with faint fluorescence can offer a budget-friendly way to enhance near-colorless stones, but strong fluorescence might affect the diamond’s appearance in natural light.
• Understand Certification Reports: Learn to read diamond certificates from reputable labs like GIA or IGI, which provide unbiased assessments of your diamond's quality.
• Think About Band Material: Choose metals that complement the diamond. Platinum and white gold enhance a diamond’s sparkle, while yellow or rose gold can add warmth and contrast.
• Ask Questions: Never hesitate to reach out to diamond experts or customer support teams for guidance—buying a diamond is a big decision, and professional advice can make all the difference.
