At Carats Exchange, we are dedicated to excellence, ensuring that every GIA-certified diamond is a true masterpiece of craftsmanship. Our mission is to provide a seamless experience for clients seeking loose diamonds, diamond exchange services, or investment-grade stones that combine luxury, quality, and enduring value.
Masterful Craftsmanship
Every diamond and piece of jewellery we offer is carefully crafted to the highest standards, designed to last for many years. We meticulously select stones based on their cut, clarity, carat, and colour, guaranteeing brilliance, beauty, and long-term value. Our commitment to precision and artistry ensures that each diamond is not just a purchase, but a lasting treasure.
Trusted Quality & Warranty
To give our clients confidence in their investment, we provide a 5-year warranty against manufacturing defects in materials or craftsmanship. This warranty ensures that your diamond remains as flawless and secure as the day you received it. By combining luxury craftsmanship with robust protection, Carats Exchange is a trusted destination for both personal milestones and long-term investment in fine diamonds.
Ethical Sourcing & Certified Diamonds
All our natural mined diamonds are conflict-free and sourced responsibly. Each diamond comes with GIA certification, verifying its authenticity and quality, while all our precious metals—including gold, silver, and platinum—are hallmarked in the UK to confirm purity and genuineness. With Carat Exchange, you can invest in luxury diamonds that are not only beautiful but ethically and professionally certified.

Conflict-free diamonds and hallmarked precious metals
Luxury and investment-grade diamonds for collectors and investors
At Carats Exchange, we believe that buying a diamond should be more than a transaction—it should be an experience defined by luxury, trust, and enduring value. Whether for a personal milestone, a bespoke collection, or investment purposes, our diamonds are chosen to ensure timeless beauty and long-term worth.
At Carats Exchange, we take great pride in the exceptional quality of our jewellery. Every piece is meticulously crafted to last for many years, combining timeless beauty with lasting durability. To give you complete confidence in your purchase, we provide a 5-Year Warranty against manufacturing defects in both materials and craftsmanship.
What Our Warranty Covers
If a manufacturing fault is discovered in the way your jewellery was made, we will repair, remake, or replace it at no cost to you within the first five years of purchase.
What Our Warranty Does Not Cover
Our warranty does not extend to accidental damage, general wear and tear, loss, theft, or work carried out by another jeweller. For example, damage caused by catching a ring on a door handle, losing an earring, or misplacing a bracelet would not be covered. Additionally, if a piece has been altered, resized, or repaired by a jeweller other than Carats Exchange, the warranty becomes void.
Returns for Peace of Mind
We want you to feel completely at ease when shopping with us. That’s why we offer a 30-Day Money-Back Guarantee on standard purchases (custom-made items are excluded).
Conflict-Free & Certified Quality
All of our natural mined diamonds are conflict-free, and every piece of gold, silver, and platinum jewellery is fully hallmarked in the UK to verify its purity and authenticity. You can shop with confidence knowing your jewellery is ethically sourced and officially certified.
If Something Goes Wrong
Whatever the issue—whether it’s our responsibility or due to accidental damage—we encourage you to send your jewellery to us for a professional assessment.
If it’s a manufacturing fault, we will repair it at no charge.
If the damage was accidental, we’ll provide a fair, transparent repair quote with no obligation.
At Carats Exchange, we believe luxury should be paired with lasting care. Our team is here to ensure your diamonds and jewellery remain as beautiful as the day you received them.
