Just by looking at the picture of these 1.25ct Tanzanite round stud earrings and Diamonds, you can see the intense blue-violet color. This size is one of our most popular sizes to sell. Normally 1ct Tanzanite earrings are not this intense, but we only use the best colors in all our earrings. The measurements are 5mm x 5mm. Accented with these stud earrings, are two round brilliant Diamonds. You can even choose 14kt white gold or yellow gold. This is a classic earring with colors that will stand out brilliantly.
