Diamond Education
Understanding diamonds helps you make confident decisions. Here's everything you need to know before designing your piece.
Our Diamonds
Every Estella Rose piece is set with IGI-certified diamonds that meet our strict quality standards. Our diamonds are chemically, physically, and optically identical to mined diamonds — composed of pure crystallized carbon with the same hardness (10 on the Mohs scale), refractive index, and brilliance.
We source our diamonds from trusted suppliers and hand-select each stone for exceptional cut, clarity, and fire. During your consultation, we'll walk you through the specifications and help you find the right balance of size, quality, and budget for your piece.
Understanding the 4Cs
Carat
Carat refers to the weight of a diamond, not its size. One carat equals 0.2 grams. Our custom tennis bracelets range from 2ct to 10ct+ total weight, and necklaces from 3ct to 15ct+. During your consultation, we'll help you decide the ideal carat weight for your piece.
Cut
Cut determines how well a diamond reflects light — it's the most important factor in a diamond's brilliance. We use only Excellent and Very Good cut grades to ensure maximum sparkle and fire in every stone.
Color
Diamond color is graded from D (colorless) to Z. Our diamonds range from D to G — the finest color grades — ensuring each stone appears white and brilliant. Higher grades are available in our Premium and Exceptional quality tiers.
Clarity
Clarity measures internal inclusions or surface blemishes. Our diamonds range from IF (internally flawless) to VS2. In our Brilliant tier, inclusions are invisible to the naked eye. In Premium and Exceptional tiers, they're virtually undetectable even under magnification.
IGI Certification
Every diamond we use is independently certified by the International Gemological Institute (IGI), one of the world's most respected gemological laboratories.
Each certification report includes a detailed assessment of the diamond's 4Cs — carat, cut, color, and clarity — along with additional measurements and characteristics. This report serves as an independent verification of your diamond's quality and specifications.
Your IGI certification is included with every finished piece, giving you complete confidence in your purchase.

Common Questions
What's the difference between your quality tiers?
Our Brilliant tier features VS clarity and F-G color diamonds — excellent quality with exceptional sparkle. Premium uses VVS clarity and D-E color for near-flawless stones. Exceptional offers internally flawless to VVS1 clarity with D color — the finest grade available.
How do I choose between carat weight and quality?
It depends on your priorities. Higher carat weight means more visual impact, while higher quality means each stone is closer to perfection. During your consultation, we'll help you find the right balance for your budget and preferences.
Are your diamonds real diamonds?
Yes. Our IGI-certified diamonds are chemically, physically, and optically identical to mined diamonds. They are composed of pure crystallized carbon with the same hardness, refractive index, and brilliance.
Can I see the diamond specifications before committing?
Absolutely. After your consultation, we send a detailed written quote with exact diamond specifications, IGI certification details, and a reference image — all before you commit to anything.
