This is a Moissanite Tennis bracelet. This is the most comparable stone when it comes to comparing to a diamond. It shines brighter, lasts just as long and passes a diamond tester. Please don’t mind if some pictures seem blurry as it is the only way to pick up how much the piece shines. Every single piece we sell will come with an official GRA certificate showing its authenticity and all of the specifications. These are VVS stones. Any questions or videos of proof needed in terms of authenticity please let me know I will be more than happy to provide. Shipping will take about 5-9 business days! Thank you!
