Gems and Precious Stones

You can take a chunk of mineral stone to a local gem and mineral show, where experts often appraise specimens. Additionally, visit a geology department at a nearby university or a rock and mineral shop, as they may offer valuations or connect you with someone who can. Online platforms and mineral appraisal services are also available for remote assessments.

Yellow topaz is formed through the crystallization of aluminum silicate fluoride in igneous rocks, particularly in granite and rhyolite. The presence of trace elements, particularly chromium and iron, contributes to its vibrant yellow color. Over time, geological processes such as heat and pressure can further enhance its clarity and brilliance, resulting in the beautiful gemstones we see today. Additionally, yellow topaz can be found in alluvial deposits, where erosion has transported the crystals away from their original source.

Topaz was formed at a high temperature, and is commonly found in igneous rock.

Diamonds weighing 23 carats means that each diamond weighs a total of 23 carats. Carat is a unit of weight used to measure gemstones, with one carat equalling 0.2 grams. So, a 23-carat diamond is quite large and valuable.

Jade is a name given to two metamorphic ornamental gem stones; nephrite and jadeite. Nephrite is softer than jadite and has less varity of colour. Nephrite varies from white to green, jadeite varies from blue through lavender to an emerald green. Nephrite is more abundant than jadeite which is only found in 11 places in the world. The rarest and historically most sought after jade is a jadeite of translucent emerald green.

Tumblestones are small, polished stones used for decorative purposes, often in crystal healing or metaphysical practices. They are typically tumbled in a machine to create smooth, shiny surfaces and are believed to have various energetic properties.

Like diamonds, the cost of topaz depends on the colour of the topaz and the clarity. I am not a jeweler, but was just reading that the pink ones are the most valuable followed by the more vibrant blues. The whitish blue ones aren't as valuable in comparison. Again, like diamonds, they can have inclusions (cracks or specks inside the stone) that make the stone less vibrant. This impacts the price as well as how well the stone is cut.

The website I was reading says that topaz can range from $20 to $1000.
