About Diamonds

Diamonds are one of the most sought-after gemstones due to their lustre, durability and rarity. The name comes from the ancient Greek meaning 'unconquerable'. They're the hardest natural substance on earth, made up of nearly 100% carbon and the only thing that will scratch one is another diamond! Diamonds are mined worldwide in locations such as Australia and USA. Diamonds measure 10 on the Mohs hardness scale.

Jewellery Making With Diamonds

Diamonds are extremely popular for engagement rings, and as the birthstone of April, they make brilliant gifts for birthdays. At Kernowcraft we have a huge range of diamonds to choose from in the form of cabochons, faceted stones and beads in a range of colours and sizes.

Shop our range of  jewellery settings for faceted stones or our range of beading threads and jewellery findings to get making! We also have an extensive range of silversmithing supplies for all your needs. Explore our beginner's jewellery making kits with step by step instructions for inspiration or check out our jewellery making tutorials on silversmithing, wire-wrapping, beading, stone setting, texturing and more.

Affordable Alternative To Diamonds

If you're after an affordable alternative to diamonds,  cubic zirconia stones are a great choice. Although cubic zirconia is a made-made stone, you cannot tell the difference between the stones. They have an incredible clarity and sparkle, making them a really popular stone for jewellery making. You may also be interested in our incredible Cubic Zirconia Cullinan Diamond Replica Collection! Our large faceted stones are the ultimate collector's piece for gemstone lovers. It includes the famous Cullinan I teardrop diamond, known as the Great Star Of Africa - the largest polished white diamond in the world. Among this, we also have a range of other shapes within the collection. Find out more here.

Diamond Gemstone Meaning

Known as the 'Master Healer', the diamond is said to remove negative energies, bring love and clarity among relationships and is a symbol of commitment. Find out more about them in our blog Designing with Diamonds.
