Frequently Asked Questions

Yes, all diamonds used in MIYOCO jewelry are 100% natural, carefully selected from ethically sourced origins. We do not use synthetic or lab-grown diamonds, as we believe in preserving the natural beauty and heritage of authentic gemstones.

At MIYOCO, we only work with suppliers who adhere to strict conflict-free guidelines. All of our diamonds are certified by organizations like the Responsible Jewellery Council and comply with Kimberley Process standards. Our diamonds are sourced from partners who share our commitment to responsible and socially conscious practices, ensuring every stone reflects the values we stand for.

MIYOCO is deeply committed to sustainability. We use 100% recycled gold in all of our designs and source our diamonds from suppliers who adhere to environmentally responsible practices. By choosing MIYOCO, you are supporting a brand that prioritizes ethical production and transparent sourcing, contributing to a greener, more socially responsible jewelry industry.

Certified diamonds come with a grading report from a trusted gemological institute, such as GIA or HRD, that details their characteristics (4Cs) and authenticity. Every MIYOCO diamond above 0.30 carats is certified and engraved with a unique serial number. For uncertified diamonds, our expert gemologists in Valenza conduct thorough assessments to guarantee that even uncertified stones meet our high standards for quality and beauty.

The cut is crucial because it directly affects how well a diamond reflects light, determining its sparkle. At MIYOCO, we specialize in selecting diamonds with Excellent or Very Good cut grades. Our 3D CAD design process is meticulously crafted to respect the stone’s natural brilliance, ensuring that the diamond’s light performance is maximized, and the side stones enhance the radiance of the center stone.

A Triple Excellent diamond is one that has received the highest grade — Excellent — for cut, polish, and symmetry from a gemological institute like GIA. At MIYOCO, we offer diamonds that meet or exceed these standards, ensuring exceptional brilliance and light performance in every piece of jewelry.

MIYOCO exclusively uses diamonds graded VS2 (Very Slightly Included) or higher for clarity and G (near colorless) or better for color. This ensures that our jewelry maintains the highest aesthetic quality, while still offering a range of diamond options tailored to individual preferences.

Carat weight measures the size and weight of the diamond, but it’s not the only factor in determining its beauty. At MIYOCO, we help you find the perfect balance between carat weight and the other Cs (cut, color, clarity) to ensure your jewelry has both presence and brilliance. Whether you choose a 0.30 carat center stone or a larger diamond, we’ll guide you to a piece that perfectly suits your style and occasion.

To maintain the beauty of your MIYOCO jewelry, we recommend gently cleaning your diamonds with a soft brush and mild detergent or having them professionally cleaned. Avoid exposing your jewelry to harsh chemicals or extreme temperatures, and store it in a separate pouch or box to avoid scratches.

Absolutely. MIYOCO offers a bespoke service that allows you to work directly with our artisans to create a custom piece that reflects your unique vision. From choosing your ideal diamond to working on the design, we’ll ensure your jewelry is a one-of-a-kind creation.
