What are the differences between lab-grown diamonds and moissanite?
Lab-grown diamonds and moissanite are both beautiful, ethical alternatives to mined diamonds, but they’re made of different materials. Lab-grown diamonds are real diamonds, created from pure carbon and identical to mined diamonds in every way except origin. Moissanite is a separate gemstone made from silicon carbide.
Both offer incredible sparkle and durability. Lab diamonds have the classic diamond look, while moissanite offers a slightly different light performance with high brilliance. It comes down to your style, values, and budget.
What are the differences between 14k, 18k, and platinum?
14k, 18k and platinum are all excellent, durable options, with very slight differences.
14k gold has a great balance of gold content and durability, making it the most popular choice for everyday jewelry.
18k gold contains more pure gold, making 18k yellow and rose gold appear slightly richer in tone than 14k, and also slightly softer. There is no visible difference between 14k and 18k white gold.
Platinum is a naturally white, hypoallergenic metal that is also very durable.
