1.50 Ct. Topaz from Ceylon (Sri Lanka)

When you are searching for a gemstone that balances striking color, elegant proportions, and everyday durability, this 1.50 carat emerald cut blue topaz from The Natural Gemstone Company answers that need with confidence, beauty, and clarity. Transparent and clean to the eye, the gem measures 7.06 x 5.06 x 4.20 mm, and its emerald cut shape gives a classic, refined silhouette that works beautifully for engagement rings, solitaire pendants, and heirloom pieces. The checkerboard faceting across the crown adds lively reflections and a modern twist on a traditional shape, allowing the medium intensity blue to play with light and flash as it moves. With a clarity grade described as very slightly included at eye level, the stone reads as visually clean while retaining natural character, and the excellent polish enhances surface brilliance and touch.

Beyond first impressions, practical buyers want to know how a gem will stand up to daily life, and blue topaz is reassuring in this regard. Blue topaz rates about 8 on the Mohs scale of mineral hardness, which places it notably harder than common jewelry minerals such as quartz, which is 7, while placing it just below corundum varieties like sapphire and ruby, which are 9, and well below diamond at 10. That hardness means this blue topaz resists scratches from most everyday contacts and maintains facets and polish with regular wear, making it a strong choice for engagement rings and frequently worn pieces when set in a protective setting. This stone has been treated by irradiation to intensify and stabilize the blue hue, which is a common and accepted enhancement in the trade, and one that delivers vivid color without compromising structural integrity. The gem originates from Ceylon, now known as Sri Lanka, a region with a long and respected tradition of supplying fine gemstones, and this provenance adds an element of story and collectible appeal.

If your goal is a ring that feels special and endures, this checkerboard emerald cut blue topaz solves that brief with grace and value. For engagement rings, consider a bezel setting for maximum protection, or a low profile four prong setting to let light show through the stone while keeping the edges safe, and pair the cool blue with warm 18 karat yellow gold for contrast, or with white gold or platinum for a contemporary, icy look. Collectors who value locality will appreciate the Sri Lankan origin, and the medium color intensity makes this gem versatile for both daytime sophistication and evening sparkle. Care is straightforward, use mild soap and a soft brush for routine cleaning, avoid harsh chemicals and ultrasonic cleaners if the piece has delicate settings or mixed treatments, and store separately from harder stones to prevent accidental abrasion even though the stone is robust.
