Frequently Asked Questions
Find quick answers to common questions about our tennis bracelets and about our lab-grown diamonds.
Are your diamonds lab-grown or natural?
All Delve diamonds are lab-grown. They are physically, chemically, and optically identical to mined diamonds, but created in a controlled environment with a far lower environmental footprint.
Are lab-grown diamonds real diamonds?
Yes. Lab-grown diamonds are real diamonds, with the same hardness, brilliance, and sparkle as mined diamonds. The only difference is their origin.
Do your diamonds come with certificates?
Yes. Each diamond comes with an independent grading report for all Round brilliant diamonds above 0.30ct and Fancy shaped diamonds above 0.50ct are certified by IGI. The smaller stones receives a Delve diamond certificate to ensure the highest quality.
What is a tennis bracelet?
A tennis bracelet is a flexible line bracelet set with a continuous row of diamonds or gemstones, prized for its elegance and everyday wearability.
A Tennis Bracelet is one of the most iconic jewellery pieces of all time. Characterised by a continuous line of diamonds, set in a fine and flexible gold band, it’s elegant, versatile and timeless.
