A gemstone can be any rock, mineral, or material that can be cut, polished, and used in the creation of jewelry. Gemstones come in hundreds of colors, shapes, and sizes — from diamonds and rubies to sapphires, emeralds, opals, and beyond.
Gemstones are traditionally divided into Precious Stones (diamond, ruby, sapphire, emerald) and Semi-Precious Stones (everything else). However, this classification no longer reflects true value. Some opals and jades are worth more than their counterparts in the "precious" category — rarity, quality, and origin matter far more than the label.
At Krasner Jewelers, we believe all gemstones are beautiful when thoughtfully and carefully set among complementary stones. We specialize in custom jewelry using quality gems from our collection — and any heirloom stones you wish to incorporate into a new creation.
Milton Krasner has 46 years of experience selecting and sourcing colored gemstones. As a GIA Graduate Gemologist, he brings expert knowledge to every stone selection — helping you find the right color, clarity, and cut for your vision.
Colored gemstones are increasingly popular for self-purchase — a meaningful piece that represents something personal, not just a gift occasion. Rubies, sapphires, and tourmalines make stunning centerpieces for custom rings, pendants, and earrings. Come into our La Jolla studio and let us show you what's possible.
