Lab grown diamonds are real diamonds. Lab grown diamonds are created using the exact same process as natural diamonds – just within a controlled laboratory environment rather than deep underground. Through advanced technology, these diamonds form under high pressure and temperature, replicating the natural conditions that produce mined diamonds over millions of years. The result is a diamond that is physically, chemically, and optically identical to a natural one, with the same fire, brilliance, and durability. However, unlike mined diamonds, lab-grown diamonds are produced without the extensive environmental disruption, land degradation, or carbon footprint associated with traditional diamond mining. By choosing lab-grown, you get the same rare beauty and allure – without compromise, without harm.

BRAND DIFFERENCE
Our DURANT Jewellery blends 'Heritage Craftsmanship' with a modern high-fashion edge, offering exclusive, Limited Edition pieces with the level of detail and quality usually only found in antique and estate jewellery.

LAB GROWN DIAMONDS
Lab grown diamonds are real diamonds, created using cutting-edge technology that mirrors the natural diamond formation process. They possess the same brilliance, fire, and durability as mined diamonds, with identical physical, chemical, and optical properties.
Even under a jeweler’s loupe, there is no visible difference between a lab grown and a mined diamond. The only way to distinguish them is through the microscopic laser inscription on the diamond’s edge, which corresponds to its unique numerical listing on an internationally accredited GIA certificate – ensuring full transparency and authenticity.
Lab grown diamonds offer the same exceptional quality and prestige as mined diamonds but without the environmental impact or ethical concerns of traditional mining.

LAB GROWN V NATURAL
Lab grown diamonds offer identical beauty and brilliance to mined diamonds while being 100% conflict-free, sustainable, and more affordable. They are created using the exact same process as natural diamonds, just within a controlled laboratory environment rather than deep underground. Through advanced technology, these diamonds form under high pressure and temperature, replicating the natural conditions that produce mined diamonds over millions of years. The result is a diamond that is physically, chemically, and optically identical to a natural one, with the same fire, brilliance, and durability. However, unlike mined diamonds, lab grown diamonds are produced without the extensive environmental disruption, land degradation, or carbon footprint associated with traditional diamond mining. By choosing lab grown, you get the same rare beauty and luxurious sparkle, without compromise, without harm.

DIAMOND CERTIFICATIONS
All of our lab grown diamonds are certified by leading gemological institutes such as IGI or GIA, ensuring the highest quality and international authenticity.

Sizing

RING SIZE ALLOCATION
We want to ensure your ring fits perfectly. Follow these simple steps to determine your ring size:
1. Measure Your Finger Directly with our 'Online Ring Sizer'
• Please click the link under any of the ring products you admire
• Using your phone camera, scan the supplied QR code
• Follow the prompts to place your preferred finger you wish to size on your phone screen
• Make sure the dotted lines aligns directly to either side of your chosen finger, then press the 'tick'. This capture will list your ring size. Hit 'OK' to then complete your purchase.

2. Use a Ring You Already Own
• Select a ring that fits the finger you want to measure
• Lay the ring flat on a ruler and measure the inner diameter (the distance across the inside of the ring)
• Compare the measurement to the size chart below to find your size

3. Visit a Jeweler for an Accurate Measurement
• For the most accurate measurement, visit a professional jeweler and have your finger sized

4. Important Tips
• Measure your finger at the end of the day when it's warm, as fingers tend to shrink in cold temperatures
• If your knuckle is larger than the base of your finger, select a size that fits over the knuckle comfortably
• If you're between sizes, we recommend sizing up for comfort

RESIZING
• For designs that are able to be re-sized we offer one complimentary ring resizing within 30 days of purchase for DURANT Fine Jewellery (excluding eternity bands and intricate designs).
• Certain designs, particularly those featuring a continuous band of diamonds or intricate settings, cannot be resized without compromising their integrity. Rings with a full-eternity design (where diamonds or gemstones encircle the entire band) do not have an area of unset metal to adjust the size without disturbing the stone placement, symmetry, or overall durability. Additionally, intricate settings with detailed craftsmanship may not withstand alterations without weakening the structure. In these instances each ring size has its own mold and the design is amended to fit and set to each size.
• As full-eternity designs cannot be resized, each size is crafted individually, requiring a precise number of diamonds or gemstones to maintain the design's integrity. Larger ring sizes require more materials, including additional stones and precious metal, which naturally increases production costs. Each ring is carefully measured and set to ensure the perfect balance of aesthetics, durability, and comfort.
• Some of our designs contain a 'Durant Disc' at the base of the design, which is a small branded disc of metal used for easy re-sizing by your local jeweller. Please contact us for information or addition of a Durant Disc for a design that may not already hold one. Please note - a Durant Disc cannot be added to some designs.
