Bottle format: Handcraft Blends sells much larger sizes
This is the most dramatic difference between the brands. Handcraft Blends sells lavender in large bottles (2-16oz), while Plant Therapy's standard format is 1oz and Rocky Mountain Oils' is 5ml. Work out the cost per ounce yourself at the time you buy - prices change, and the format difference is what drives the gap.
If budget is a primary factor and you want a large bottle for regular diffuser use, Handcraft Blends is the obvious choice.

Plant Therapy publishes GC/MS (gas chromatography/mass spectrometry) test results directly on each product page. Rocky Mountain Oils does the same. These tests confirm the chemical composition of the oil and verify it has not been adulterated with synthetic fragrance or cheaper oils.
Handcraft Blends posts a third-party GC/MS report on the product page for nine of the eleven essential oils we checked on 4 November 2026. Frankincense, clove leaf and the carrier oils have none (oil by oil). Plant Therapy and Rocky Mountain let you find the report for a specific batch, which is the difference if you need documentation for the exact bottle you own, for example for professional use.
When to choose each brand
| Choose Handcraft Blends if... | Choose Plant Therapy if... | Choose Rocky Mountain if... |
|---|---|---|
| You want large bottles for frequent use | You want public GC/MS reports | You want a premium therapeutic grade |

| You buy frequently on Amazon Prime | You want wide variety in small sizes | You want a dedicated wellness brand |
Bottom line
For everyday aromatherapy and home use, Handcraft Blends covers everyday use well. If you need documented third-party testing for professional use, Plant Therapy is the better choice. Rocky Mountain Oils suits buyers who prioritize premium positioning over price.
