Lab-created diamonds are formed in tightly controlled laboratory settings using the latest, most sophisticated technologies that replicate the natural conditions under which diamonds are formed within the earth. They share identical optical and chemical characteristics with mined diamonds—exhibiting the same brilliance and sparkle. The sole difference lies in their origin.
Yes, lab-created diamonds will test positive on a diamond tester. Although grown by scientists in a lab instead of in the earth's crust, lab diamonds are absolutely real diamonds. They have the same chemical and optical properties as natural diamonds. Expert gemologists cannot tell the difference between the two with the naked eye. A lab diamond can only be distinguished from mined diamonds using specialized equipment that can detect the minor differences in trace elements and crystal growth.
In gemology, “color” refers not to how colorful a diamond is — but how colorless it appears. The less color, the rarer and more valuable the stone. A perfectly colorless diamond sparkles brighter and reflects light more purely.
What’s the Difference Between D, E, F and G?
These four grades all appear white to the naked eye, especially once the diamond is set in a ring. But there are subtle differences:
• D — Perfectly colorless. Extremely rare and highly prized for its purity and icy brilliance.
• E — Nearly identical to D, with microscopic traces of warmth only visible under special equipment.
• F — Slightly warmer than E, but still considered colorless. A smart balance between beauty and value.
• G — A hint of warmth under magnification, but still appears white and bright when worn.
💡 Most people cannot tell the difference between these colors without special tools — which means you can confidently choose based on your budget and preference.
Why Does This Matter for You?
Because you don’t have to compromise. Every diamond we offer has been hand-selected by our experts for exceptional beauty, clarity, and color — whether you choose a D or a G.
Unlike mass-market jewelers who offer a wide range of lower-quality stones (K to Z), we focus only on premium color grades. You can feel confident that your diamond will sparkle brilliantly — and look stunning for life.
The 4C’s (cut, color, clarity, and carat weight) is the universal method that is used for assessing the quality of any diamond, anywhere in the world. Only the combination of these four factors will help you choose a diamond of your dream.
Diamond proportions are usually more important than diamond weight.
This means that a diamond smaller in weight can be just as beautiful, valuable, and optically big as a diamond of larger carat size. This is because quality and cut play a large role in the final diamond's appearance.
Especially the cut of the diamond is very important factor. It is not the same as diamond shape. The cut determines how well the diamond reflects light and sparkles. A well-cut diamond will have more brilliance and fire than a poorly-cut diamond of the same weight and shape.
At Assel, we offer only two of the most sought-after clarity grades: VVS2 (Very Very Small Inclusions) and VS1 (Very Small Inclusions). Both deliver stunning brilliance and are considered eye-clean, meaning any natural inclusions are invisible to the naked eye.
So what’s the difference?
VVS2 diamonds have inclusions that are extremely difficult to detect even under 10x magnification. They’re ideal for those who want the highest clarity available without paying the premium for a flawless grade. VS1 diamonds have slightly more noticeable inclusions under magnification, but still nothing you’ll see without special tools. They offer the same perfect visual beauty, often at a more accessible price point.
Why we choose only these two:
✨ No visible flaws — maximum brilliance in any light
🔬 Expertly inspected — every diamond passes strict visual checks
💍 Timeless quality — clarity that ensures beauty for life
You don’t need to worry about choosing the “right” clarity — we’ve already done it for you.
Every Assel diamond is selected for perfect visual purity, so you can shop with total confidence.
Carat is the standard unit used to measure a diamond’s weight — but it’s often misunderstood. Many people assume a higher carat always means a larger-looking diamond, but in reality, carat weight and visual size are not the same.
A diamond’s shape and cut play a huge role in how large it appears. For example, a well-cut 1.5 ct oval diamond can look bigger than a deeper-cut 2 ct round diamond. The way weight is distributed affects both appearance and price — so two diamonds of the same carat weight can look noticeably different.
At Assel, we curate diamonds that maximize visible size and brilliance, not just weight. Whether you’re considering a refined 1.0 ct or a bold 2.5 ct stone, our expert team helps you choose a diamond that looks exceptional on your hand — not just on paper.
Tip: If you want a diamond that looks larger without a dramatic jump in price, consider elongated shapes like oval or emerald cuts, which give more spread for the same carat weight.
Ultimately, the best carat choice is the one that fits your style, your hand, and your story — and we’re here to help you find it.
