Yasamine Co. is a fine jewelry company specializing in lab diamond and moissanite jewelry. All pieces are fully custom and made to order in the USA. Moissanite is a lab created gemstone that has gained popularity as an affordable alternative to diamonds due to its durability, conflict-free and eco-friendly nature. On the Mohs scale, moissanite scores a 9.25, a very high score that makes it one of the hardest substances on earth, and very suitable for everyday wear as an engagement ring. We also source lab created diamonds directly from Surat, India (the diamond cutting capital of the world) and will work with you to select the ring diamond for your budget. As an online company serving customers all over the world, Yasamine Co. is committed to superior customer service. Each customer receives one-on-one service through email, video and phone to custom create their engagement ring, or any other piece of custom jewelry.
